  • [00:06:16] <pupnik_> can the omap3 dsp send audio to the DAC without interrupting the CPU (GPP)? http://www.slideshare.net/vjaquez/the-dspbios-bridge-omap3-3110733
  • [00:06:33] <mru> if you let it
  • [00:06:41] <mru> it has full access to L3
  • [00:06:49] <mru> unless you block it with the mmu
  • [00:07:37] * pupnik_ is now known as pupnik
  • [00:12:55] <pupnik> ty mru
  • [00:13:55] <mru> you'd also need an mcspi driver on the dsp of course
  • [00:14:12] <mru> and convince the linux driver to hand over control of some channels to the dsp
  • [00:14:25] <mru> but those are software details
  • [00:15:08] * mrcan (~mr.mcan@78.171.72.84) has joined #beagle
  • [00:15:08] <mru> any L3 initiator can in principle do anything with the system
  • [00:15:30] <mru> hmm, I wonder if the sdma could be fashioned in to a turing machine of sorts
  • [00:15:39] <mru> *into
  • [00:15:46] <pupnik> hahah
  • [00:16:14] <mru> it could possibly be done
  • [00:16:28] <mru> by dma-ing onto the command registers
  • [00:16:49] <mru> the omap4 sdma should be even easier
  • [00:16:56] <mru> since it supports linked lists of commands
  • [00:17:12] <pupnik> do you know of any demo code that plays audio without using linux/alsa to output?
  • [00:17:21] <mru> no

  • [00:19:46] <ds2> mcbsp you mean?
  • [00:20:17] <ds2> usually there are DMA stuff you also need to take care of
  • [00:22:58] <mru> bsp, right
  • [00:23:04] <mru> though it's pretty much the same thing
  • [00:23:27] <mru> dsp has own dma
  • [00:23:32] <mru> if needed
  • [00:24:11] <ds2> it shouldn't be too hard to hand over control of a McBSP channel as long as the DSP limits itself to sending on it
  • [00:24:36] <mru> as I said, nothing in the hw prevents it
  • [00:24:59] <ds2> add a flag to to the mcbsp code in the ALSA SoC driver. if it is set, make all the calls to the mcbsp lib a dummy. if it is not, do it normally
  • [00:25:01] <pupnik> nice project
  • [00:25:07] <ds2> set flag and let the dsp churn away
  • [00:25:16] <ds2> of course, you loose recording when done this way
  • [00:25:24] <ds2> (unless you want to record to dsp)
  • [00:25:45] <mru> who cares about recording?
  • [00:25:48] <ds2> might have to dummy up the underflow interrupts
  • [00:26:00] <pupnik> well, cpu could send chunks of audio (ogg/mp3) to dsp and spend most of it's time sleeping - using device as a player
  • [00:26:20] <mru> it could load up an entire file at a time in memory
  • [00:27:58] <pupnik> sad when such features are under-utilized
  • [00:28:18] <mru> it'll only get worse
  • [00:28:33] <mru> with a brand-new soc each year, nobody will spend the time tuning code

  • [02:23:25] <thurbad> beagle2 did you see my questions?
  • [02:24:02] <beagle2> no...i think i got d/c'd
  • [02:24:05] <beagle2> let me bring up the log
  • [02:24:15] <beagle2> that happened to me like 3 times today for some reaosn, by the way
  • [02:25:28] <beagle2> um, i am on a minicom connection with my board...does that answer your question?
  • [02:25:53] <beagle2> but no, i just realized that i am using a friend's old image which (appeared) to work but for all i know he changed the pass on me
  • [02:26:14] <thurbad> ah, so it is a console
  • [02:26:39] <thurbad> yeah grab a new image if that's the case
  • [02:28:02] <beagle2> trying but i bet i'll screw it up aain
  • [02:28:20] <beagle2> i want to unmount my drive before i untar the image to the filesystem, right?
  • [02:28:52] <thurbad> how do you plan on untarring to an unmounted partition?
  • [02:29:25] <beagle2> hmmm, i guess i am more new to linux than i thought...
  • [02:29:43] <beagle2> k, i will leave it mounted.
  • [02:29:53] <thurbad> the tar version you just reformat (or simply delete the current contents) and then untar onto it
  • [02:30:59] <thurbad> pretty sure you need to use sudo with the tar command there
  • [02:31:54] <beagle2> ok, so at the moment:
  • [02:32:08] <beagle2> i have ran mkcard.txt, check
  • [02:32:17] <beagle2> i have /dev/sdb1 mounted,
  • [02:32:23] <beagle2> and i have /dev/sdb2 mounted

  • [02:32:37] * tdh2002 (~tt@59.42.56.126) has joined #beagle
  • [02:32:51] <beagle2> so do i run the command to untar it with a destination '/mnt'?
  • [02:33:09] <beagle2> cause how do i know which partition it is going to then...?
  • [02:34:23] <thurbad> you should have two partitions under /mnt or /media for the SD card... depending on your system
  • [02:35:03] * killring (~killring@adsl-76-226-108-72.dsl.sfldmi.sbcglobal.net) Quit (Ping timeout: 246 seconds)
  • [02:35:24] <thurbad> for instance on Ubuntu I have /media/ROOT and /media/BOOT when I insert my SD card your partition names are likely different
  • [02:38:01] <thurbad> so on my system I would use: sudo tar xjvf <filename> -C /media/ROOT/
  • [02:38:33] * robtow (~rob@nat/ti/x-vubkrnwsiesjhsca) Quit (Quit: Leaving.)
  • [02:38:46] <beagle2> alright, i think it automatically gives mine 'Angstrom' so i will go with that
  • [02:39:05] <beagle2> so is it basically nonsensical to temporarily mount both my partitions as /mnt?
  • [02:39:15] <djlewis> can't
  • [02:39:30] <thurbad> yes, only one thing can be mounted to a single location at any one time
  • [02:39:48] <beagle2> k...well it allows me to do it, lol
  • [02:40:02] <beagle2> anyways, the tar is almost complete, then i go replace the uImage, right?
  • [02:40:03] <thurbad> the second mounting would replace the first one
  • [02:40:26] <beagle2> and then for step 5 of http://www.angstrom-distribution.org/demo/beagleboard/, how do i 'ensure all filesystems have completed'?
  • [02:41:00] <beagle2> ah, that makes sense for the mounting, it is annoying that they both still show up under '/mnt' for 'df' command though
  • [02:41:18] <beagle2> anyway, it appears that the untarring is working fine (fingers crossed)
  • [02:41:41] <thurbad> use either eject or unmount both partitions
  • [02:41:42] <beagle2> i really think this whole tut is rather straight-forward, but i still wasn't able to get it to work at the end of the day
  • [02:41:47] <beagle2> hopefully this time will be different...
  • [02:42:15] <beagle2> oh, that all step 5 is saying?
  • [02:42:16] <beagle2> cool
  • [02:42:24] <thurbad> eject would be a right click option from your desktop
  • [02:43:08] <thurbad> yes, some people just pull the SD as soon as tar finishes, but the disk writing isn't complete because of caching
  • [02:43:08] <beagle2> ya, or the lile button in the device list, right?
  • [02:43:18] <beagle2> aaahhhh, that makes sense
  • [02:43:23] <beagle2> caching i semi-understand, lol
  • [02:45:49] <beagle2> wooooot
  • [02:45:54] <beagle2> i got my root@beagleboard:~#
  • [02:45:56] <beagle2> :)
  • [02:45:56] <thurbad> basically the tar command has finshed writing to the buffer, but the buffer still hasn't finished writing to the physical media, it's used to speed up stuff that relies on occasional writing
  • [02:46:06] <beagle2> u must be good luck, thurbad
  • [02:46:17] <beagle2> ya, i got you know
  • [02:46:22] <beagle2> k, now for the next phase:

  • [04:43:24] <djlewis> if you installed the toolchain as was recommended you have what you need

  • [04:52:40] <beagle2> so i'm getting something really interesting happening:
  • [04:53:07] <beagle2> i log in to Angstrom just fine, enter 'root' to get one, then in like 2 sec it reloads everything on me...
  • [04:55:05] <beagle2> and now it's not working at all, hmmm..

  • [04:57:31] <beagle2> djlewis: have you ever seen this problem?
  • [04:57:45] <beagle2> i log into Angstrom, then it kicks me out immidiately?
  • [04:58:32] <djlewis> describe "reloads everything"
  • [04:59:02] <djlewis> where does it begin from ( reloading )?
  • [04:59:15] <beagle2> saying which x-loader I have
  • [04:59:27] <beagle2> which is the first thing i get when i start it normally
  • [04:59:32] <djlewis> what are you using for a power source?
  • [04:59:53] <beagle2> barrel to a powered USB hum
  • [04:59:55] <beagle2> hub*
  • [05:00:12] <beagle2> should i just use a 5V barrel directly?
  • [05:00:23] <djlewis> might not be enough power. Do you have a regulated 5vDC to use?
  • [05:00:40] <djlewis> with center pin +
  • [05:01:10] <djlewis> 2 amps is recommended for the XM. I use 2A on my older rev C2
  • [05:01:18] <beagle2> i am using a 'K+H Project Board', that is connected into the wall
  • [05:01:34] <beagle2> with a three-pin plug, is that what you are asking?
  • [05:01:52] <beagle2> the board is pretty hefty, so I would assume it is regulated...
  • [05:02:01] <beagle2> let me measure what is on the board
  • [05:02:09] <djlewis> no. in the SRM idt describes the correct power and connector polarity to use.

  • [05:03:27] <beagle2> ah, ok, so go look at the documentation?
  • [05:03:36] <beagle2> i had it working with this setup a few hours ago
  • [05:03:46] <djlewis> XM?
  • [05:04:02] <djlewis> either way my first suspicion is power.
  • [05:04:06] <beagle2> the only thing i changed was plugging various things into the USB hub, but i channged it back to how i think it was...
  • [05:04:13] <beagle2> ya, it makes good sense
  • [05:04:19] <beagle2> and I have a rev C$ board
  • [05:04:22] <beagle2> c4*
  • [05:04:28] <djlewis> the usb hub can only deliver 500mA, not more
  • [05:04:53] <beagle2> ok, so try it without the hub?
  • [05:05:06] <djlewis> the barrel jack is a better way to go unless you use the PM kernel
  • [05:05:26] <djlewis> and then I dont know what one gets into
  • [05:05:59] <beagle2> well i am using the barrel, i have a USB/barrel connector
  • [05:06:13] <beagle2> but now i am trying it straight through to the board
  • [05:06:56] <beagle2> ya it seems to like the power now
  • [05:07:32] <beagle2> so should I just connect my hub to the fast USB port, in your oppinion?
  • [05:07:51] <beagle2> whoops, i spoke too soon, it still recycling...

  • [06:15:38] <thurbad> if you're still unable to find it
  • [06:16:07] <thurbad> that's still the non-xM version
  • [06:16:10] <beagle2> i got it now...thanks thurbad
  • [06:16:26] <beagle2> i have C4, so i think that's what i want, yes?
  • [06:16:31] <thurbad> yes
  • [06:16:57] <beagle2> you said /ect/network/interfaces will show me my connections, but i don't see that directory...
  • [06:17:17] <beagle2> nvm, found
  • [06:17:29] <beagle2> i wish it just started you at the root...
  • [06:18:15] <thurbad> I'm not sure if eth0 is even autostarted for you or not
  • [06:18:50] <beagle2> if only i didn't have to learn the Beagle AND linux in like 3 days...
  • [06:19:21] <thurbad> are you still using the serial console, or have you moved to X windows?
  • [06:19:43] <beagle2> um, minicom...is there something better I should do?
  • [06:19:50] <beagle2> like sh into it?
  • [06:19:57] <thurbad> no, minicom's fine... just curious
  • [06:20:25] <thurbad> if you were logged in through X windows it would probably start the network manager and connect for you
  • [06:21:07] <thurbad> though that can be annoying if you need a specific IP address

  • [06:22:18] <beagle2> i just need internet, i'm going through a router to my school network
  • [06:22:26] <beagle2> k, i found eth0 on the list
  • [06:22:49] <thurbad> does it have DHCP enabled on the router? or do you need to specify a static address?
  • [06:22:59] <beagle2> static
  • [06:23:24] <thurbad> ok, you'll need to modify your /etc/network.interfaces file
  • [06:23:43] <thurbad> ... network/interfaces not .
  • [06:24:00] <beagle2> i got ya, what do i change on the entry?
  • [06:24:10] <beagle2> and is it eth0 or usb0?
  • [06:24:29] <beagle2> i think some tutorial said you can mount your BB as usb0 on Ubuntu machine, which confused me...
  • [06:26:35] * emeb1 (~ericb@ip70-190-178-182.ph.ph.cox.net) has left #beagle
  • [06:26:56] <beagle2> i think i found some documentation that'll help on that...
  • [06:27:20] <beagle2> but i am still annoyed at my hardware, i don't think it is connected yet
  • [06:27:34] <beagle2> and yes, i read the hook-up section of the SRM, but i just don't get it
  • [06:27:36] <thurbad> depends a little on your adapter, but my usb-ethernet shows up under eth0 (for instance)
  • [06:27:44] <beagle2> it doesn't spell it out in plain english what the best way is
  • [06:28:03] <thurbad> your config should look something like this http://pastebin.com/iprHUrve
  • [06:29:43] <beagle2> ya, that looks like what this tutorial is saying too....
  • [06:29:49] <thurbad> you can share the connection from a host machine over the OTG as usb0 on the host.. that's a little more complex
  • [06:29:54] <beagle2> i have an eth1 listing as well, does that matter?
  • [06:31:22] <thurbad> no, you shouldn't need that
  • [06:31:28] <thurbad> but just leave it
  • [06:33:45] <thurbad> if you werent's provided with dns servers, you can try pointing the first entry at the router/gateway or even remove it
  • [06:34:07] <thurbad> the 4.4.4.2 should probably be 4.2.2.2 instead... that's an open dns server

  • [06:37:42] <thurbad> btw you were asking about the best way to compile a C++ app earlier... the easiest way in the long term is to write a Makefile for your project and use the make command
  • [06:38:55] <beagle2> ya, that is what it is looking like...
  • [06:39:11] <aholler> you could checkout cmake too. I'll prefer that.

  • [06:40:07] <thurbad> does cmake work natively on the beagle, I seem to remember running into an issue with that
  • [06:40:44] <aholler> must have been an angstrom problem.
  • [06:41:05] <thurbad> yeah it was a problem in the OE recipe
  • [06:41:27] <thurbad> that may have been resolved by now though.. this was close to a year ago
  • [06:41:44] <beagle2> makefiles aren't that hard to learn though, right?
  • [06:41:56] <beagle2> i've read over a few, for classwork
  • [06:42:17] <thurbad> for small projects they can be very simple
  • [06:42:49] <thurbad> they can become complex, but you probably won't need to get into anything very complex
  • [06:42:51] <beagle2> i am looking at working with 20-40 lines of C++ with openGL libraries
  • [06:43:01] <beagle2> openCV libraries*
  • [06:43:10] <beagle2> hmmm, still not seeing any internet...
  • [06:43:25] <beagle2> maybe it isn't getting power from the hub, there's a limit it can support, right?
  • [06:43:34] <thurbad> did you restart the beagle?
  • [06:43:41] <beagle2> no, i'll try that
  • [06:43:51] <thurbad> you don't need to
  • [06:44:04] <beagle2> well, i did just to be safe :)
  • [06:44:10] <thurbad> but if not you should at least run /etc/init.d/networking restart
  • [06:44:31] <beagle2> does that reload the file?
  • [06:45:05] <thurbad> reloads the entire networking system, so yes in a round about way
  • [06:45:55] <beagle2> alright
  • [06:46:08] <beagle2> hmmm, it doesn't show any eth0 device at start-up
  • [06:46:23] <beagle2> and i don't have any signal lights lit up on the adapter...
  • [06:46:31] <beagle2> if i can get internet for the board tonight,
  • [06:46:34] <beagle2> i can go to bed happy.
  • [06:46:54] <aholler> still not learned dmesg?
  • [06:47:09] <thurbad> you're using a self powered usb2.0 hub?
  • [06:48:13] <beagle2> aholler: i've used dmesg some...what are you suggesting i use it for?
  • [06:48:36] <beagle2> yes, i have a powered USB hub,
  • [06:48:41] <aholler> coffee
  • [06:48:45] <beagle2> connected to the Beagle via the USB host,
  • [06:48:59] <beagle2> + a USB-barrel for power,
  • [06:49:09] <thurbad> just making sure
  • [06:49:11] <beagle2> + the USB-ethernet adapter
  • [06:49:28] <thurbad> what does lsusb show
  • [06:49:31] <beagle2> should i try powering it with just the USB host and no barrel, or does that make no sense?
  • [06:49:40] <thurbad> no
  • [06:49:55] <beagle2> 2 devices
  • [06:50:05] <beagle2> Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  • [06:50:15] <beagle2> the second is the same, but 'Bus 002'
  • [06:50:45] <thurbad> ok, then it's not seeing your device on the USB hub
  • [06:50:53] <beagle2> so it sounds like I actually have the hardware connected right, from semi-understanding the SRM and my friend's instruction's, yay
  • [06:51:18] <thurbad> do you have a spare keyboard or something that you can plug into the hub?
  • [06:51:18] <beagle2> ah, i see what you mean...
  • [06:51:25] <beagle2> ya, hang on

  • [06:57:57] <thurbad> sounds like your hub may either be dead or not a 2.0 hub?
  • [06:58:03] <beagle2> and nothing is suppose to be connected to my laptop, other than the serial, right?
  • [06:58:12] <thurbad> correct

  • [06:58:31] <beagle2> yay, i can debug still...
  • [06:58:40] <beagle2> um, it says 2.0 on the back of it....
  • [06:59:09] <beagle2> and i don't think it is DEAD-dead, because i am getting power to it from the breadboard,
  • [06:59:15] <beagle2> that i am then passing on to the BB
  • [06:59:27] <beagle2> and i know my friend used this very hub last year...
  • [06:59:54] <thurbad> there's a breadboard in the mix?
  • [07:00:25] <beagle2> ya, it's my 'regulated' supply
  • [07:00:43] <beagle2> my friend said that it was a good way to power it...
  • [07:00:59] <beagle2> he also said i could power it straight from the computer, which i haven't tried yet
  • [07:02:15] <thurbad> it doesn't have a standard power supply?
  • [07:02:24] <beagle2> ya, the breadboard reads 5.03V
  • [07:02:30] <beagle2> what doesn't the BB?
  • [07:02:55] <beagle2> he only have me a barrel-USB, and a barrel with two leads, for a breadboard
  • [07:03:27] <beagle2> he is rather on the frugal side, and i didn't have time to order an actual supply before this presentation :)
  • [07:03:41] <beagle2> rest assured though, he used all these components successfully last year
  • [07:04:29] <thurbad> hmm, normally I'd suggest pluging the hub into your desktop and checking it, but am a little leary of suggesting that now
  • [07:04:51] <beagle2> y?
  • [07:05:09] <thurbad> why the former, or why the latter?
  • [07:05:22] <beagle2> why shouldn't we try it? lol
  • [07:05:45] <beagle2> so just to confirm: i don't want to be using the OTG for anything?
  • [07:05:56] <thurbad> because if it's not functioning right I don't want to see a fried laptop
  • [07:06:06] <beagle2> ooo
  • [07:06:15] <beagle2> thanks.
  • [07:06:22] <beagle2> i can plug it into one of the lab computers... :)
  • [07:07:35] <thurbad> the otg can be a little problematic with the 2.6.32 and higher kernels
  • [07:07:38] <beagle2> well that's interesting...'lsusb' still sees two devices, even when i disconnect the host USB

  • [07:08:30] <beagle2> ya, even though nothing is connected to them?
  • [07:08:48] <beagle2> it says they are both '2.0 root hub's
  • [07:08:51] <thurbad> sure, they still act as hubs
  • [07:08:56] <beagle2> true
  • [07:09:03] <beagle2> well, this is a conundrum
  • [07:09:21] <beagle2> i suppose i'll just wait for my friend to call back, who got this exact setup working before
  • [07:09:29] <beagle2> which will be after my presentation, sigh...
  • [07:09:40] <thurbad> not the same kernel though?
  • [07:09:50] <beagle2> any last thoguhts before i call it a night?
  • [07:09:59] <beagle2> just glean what I can from the SVM?
  • [07:10:13] <beagle2> it seems like my intuition for how to connect the hardware was right though...
  • [07:10:20] <thurbad> do yourself a favor and purchase a standard 2.0 self powered usb-hub, they'
  • [07:10:27] <beagle2> ah, that's true, i assume the kernal is different
  • [07:10:28] <thurbad> re only abouut $20

  • [07:21:02] <beagle2> way to go*
  • [07:22:04] <beagle2> http://narcissus.angstrom-distribution.org/
  • [07:22:20] <beagle2> what are your thoughts, vs. the demo image?
  • [07:23:39] <thurbad> the demo image has lots of stuff built in that you won't need
  • [07:23:47] <beagle2> mmm
  • [07:24:41] <thurbad> at this point what do you need networking for?
  • [07:25:36] <thurbad> I believe that the demo image already has task-sdk-native included, and if not you can use narcissus to build an image that does include it
  • [07:26:19] <beagle2> wait, the image i have has this 'task-sdk-native' on it?
  • [07:26:24] <thurbad> probably
  • [07:26:30] <beagle2> then why does it not recognize it when i say to install it?
  • [07:26:38] <thurbad> type in make and see what it says
  • [07:27:13] <thurbad> because you have to update first, and you can't update without an internet connection
  • [07:27:24] <beagle2> ah...i see
  • [07:27:34] <beagle2> so i need an internet connection for like, two seconds,
  • [07:27:36] <beagle2> and then i'm good
  • [07:27:41] <beagle2> is that the gist of it?
  • [07:28:19] <thurbad> depends on wheteher you're going to be loading up on not so standard stuff.. which is probably not the case for a small classroom demo
  • [07:29:30] <beagle2> hey now, this is my Senior Design Project
  • [07:29:38] <beagle2> but in terms of coding, it is pretty basic
  • [07:29:53] <beagle2> i really only need a high/low signal at the end of the day,
  • [07:29:59] <beagle2> and the USB to plug a webcam into
  • [07:30:18] <beagle2> and basic C++ libraries + openCV, that's it.
  • [07:30:40] <beagle2> i am beginning to think BB was the wrong way to go...but too late to back out now.
  • [07:30:59] <beagle2> all i know is that it is relatively straightforward to run C code on them,
  • [07:31:08] <beagle2> but relativity sucks.
  • [07:31:41] <thurbad> kinda steep if you've never used linux before
  • [07:32:03] <thurbad> but not a bad solution overall
  • [07:32:43] <thurbad> although our engineer is not very fond of the omap layout :P
  • [07:34:29] <thurbad> not sure exactly what /is/ fond of though
  • [07:34:47] <beagle2> i hear you
  • [07:35:00] <beagle2> at least i got a good hold of linux these last few days
  • [07:35:14] <beagle2> and I've gotten a pretty Angstrom logo to pop up, lol
  • [07:35:43] <beagle2> but ya...i'll be back on here tomorrow some, but I think I'm at that point where I've just accepted it is impossible to get it for this milestone at least
  • [07:36:04] <beagle2> especially since that friend of mine came in here and said he took two weeks to get it working, and he's a genious.
  • [07:36:52] <thurbad> nah, shouldn't be
  • [07:37:14] <thurbad> if most of your other work is complete
  • [07:37:17] <beagle2> haha, not impossible to have it in...a little less than 14 hours?
  • [07:37:24] <beagle2> my C++ code?
  • [07:37:33] <beagle2> ya, i just need to touch that up for like half hour or so
  • [07:37:41] <beagle2> but like, i kind of want to sleep,
  • [07:37:49] <thurbad> yeah, sleep's good
  • [07:37:50] <beagle2> but if there is a chance i can get this for the demo...
  • [07:38:06] <beagle2> plus my groupmates have their parts done, technically,
  • [07:38:12] <thurbad> did you try the make command yet?
  • [07:38:21] <beagle2> but i still have to worry about interfacing with all their stuff, and physically mounting the camera, ect...
  • [07:38:28] <beagle2> just type 'make'?
  • [07:38:34] <beagle2> ya, it doesn't recognise it...

  • [07:39:11] <thurbad> you can definitely include it in a custom narcissus online build
  • [07:39:33] <beagle2> ya, it seems like that'll be stronger in the end, if a little more complicating up front
  • [07:39:54] <beagle2> i may try it tomorrow afternoon, but really, i should make the stupid presentation as good as it can be w/o my board...
  • [07:40:41] <beagle2> hmmm, they have an openCV option under the development selections...
  • [07:41:01] <thurbad> yes
  • [07:41:32] <beagle2> thurbad: i am assuming the resulting image from narcissus will take an equatably long time to d/l as the demo image did,
  • [07:41:41] <thurbad> you can probably get everything but the webcam working without a network connection
  • [07:41:48] <beagle2> so i am thinking it'll make sense to start it tonight and have it done for tomorrow when i come in...
  • [07:42:18] <beagle2> couldn't i in theory just transfer stuff to the board via SD cards or sh anyway?
  • [07:42:32] <beagle2> even if it is a bit more painful than downloading it directly?
  • [07:42:34] <thurbad> sure, it's just a hassle
  • [07:42:42] <beagle2> aye, i beat ya to it :)
  • [07:42:48] <beagle2> ya, internet would be nice...
  • [07:43:18] <beagle2> my friend said he used the visual X-window thing,
  • [07:44:10] <beagle2> and i just ordered a HDMI to DVI D Cable on amazon,
  • [07:44:36] <beagle2> so while i won't have it for tomorrow, it sounds like that'll work a lot better in opperating the BB from a GUI, i am thinking?
  • [07:44:45] <thurbad> yeah you're going to have to move away from the serial console for the dispaly
  • [07:44:54] <beagle2> and he said that is how he configured his internet connection
  • [07:45:06] <beagle2> dang, i was just getting use to minicom too...
  • [07:45:24] <beagle2> oh well, at least i get to think about it a bit more like my laptop i love so much now :)
  • [07:45:28] <thurbad> yeah, minicom is good for debugging starup errors
  • [07:45:50] <beagle2> do you have any idea what i'll need on my narcissus image, so i can start it tonight?
  • [07:46:20] <beagle2> Toolchain and mono, for compiling, right?

  • [12:40:31] <mru> don't mind me, I don't know french at all
  • [12:40:59] <mru> I just found the choice of word a little curious
  • [12:41:07] <mru> I like comparing languages like that

  • [15:05:45] <aholler> you could try to fixthe card with erasing it. e.g. cat /dev/zero >/dev/sdb will erease all on the card. (be sure that sdb is your card an not your hd). That helped here several times to bring a dead card to live again. (they have stupid wear-leveling)
  • [15:06:10] <bioster> I've been having trouble with more than one card though
  • [15:06:22] <bioster> I'm flashing a second card and am going to see if I see the same errors in the syslog
  • [15:06:51] <bioster> both cards have been dying at the same point in the boot process on the beagleboard though, so I expect it's the same issue
  • [15:07:28] <bioster> hmm, didn't get the same output in the syslog
  • [15:07:29] <aholler> sdb looks as if you used another card-reader
  • [15:08:08] <aholler> ther kernel usually uses mmc*
  • [15:08:32] <bioster> both of my card readers show up as /dev/sdX
  • [15:08:37] <bioster> b if there's nothing else plugged in
  • [15:09:09] <bioster> hmm
  • [15:09:22] <bioster> well, this card isn't being recognized at all
  • [15:09:28] <aholler> so that is an error on your pc and not the beagle, wright?
  • [15:09:30] <bioster> in the BB that is
  • [15:09:34] <bioster> correct, aholler
  • [15:09:43] <aholler> we fix all...
  • [15:10:04] <bioster> when put into the beagleboard the card that shows that error while flashing hangs just after it mounts the filesystem

  • [15:10:58] <bioster> well, the one I just flashed that the -xM wouldn't boot, it shows files on it
  • [15:11:37] <bioster> well, I have 2 cards, and 2 card readers, and 2 beagle boards, and they're all failing in all combinations I've tried

  • [15:45:23] <aholler> rev b
  • [15:45:38] <bioster> Have you tried the 10.10 install?
  • [15:45:47] <aholler> ah, xm, sorry
  • [15:45:50] <Guest44481> yes, i've tried all of them
  • [15:46:16] <Guest44481> 10.10, 10.04.2, 10.04.1, 11.04
  • [15:46:21] <aholler> have a look at dmesg
  • [15:46:29] <aholler> (using a serial)
  • [15:47:04] <Guest44481> i dont have one
  • [15:47:20] <bioster> you can look at dmesg without a serial port
  • [15:47:32] <Guest44481> okay, how?
  • [15:47:56] <Guest44481> are there any logs i can look at with plugging the sd card into my (working) computer
  • [15:47:58] <bioster> assuming it's the same as other distros, just type dmesg at the prompt
  • [15:48:00] <jkridner> at the serial port, type 'dmesg'
  • [15:48:06] <Guest44481> aah
  • [15:48:08] <bioster> (after you're logged in)
  • [15:48:10] <Guest44481> this is what the problem is
  • [15:48:14] <Guest44481> i cannot
  • [15:48:16] <Guest44481> type in anything
  • [15:48:27] <Guest44481> because the usb ports to which my keyboard is connected
  • [15:48:29] <bioster> oh
  • [15:48:33] <Guest44481> dont seem to work
  • [15:48:38] <bioster> well, you're definitely going to need to set up your serial port then
  • [15:48:43] <bioster> do you have a serial port on your computer?

  • [15:49:22] <bioster> you'd need to buy a pci card, or a usb to serial adaptor
  • [15:49:22] <Guest44481> i only have vga which looks the same but i think that doesnt help either
  • [15:49:32] <Guest44481> aaaha
  • [15:49:42] <Guest44481> good because i bought one today
  • [15:49:52] <Guest44481> how can i do this?
  • [15:49:53] <bioster> and then buy a straight through serial cable (male on one end, female on another, often just called a serial extension)
  • [15:50:27] <bioster> you run linux on your desktop?
  • [15:50:38] <Guest44481> yes
  • [15:50:47] <Guest44481> and my adaptor looks like this

  • [15:51:00] <Guest44481> can i do anything with this?
  • [15:51:18] <bioster> I haven't used that one, but I would assume so
  • [15:51:29] <Philippe> Guest44481, plug it in and se with dmesg if anything has shown.
  • [15:51:49] <Guest44481> wait a sec ill get my board powered on
  • [15:51:50] <Guest44481> sec
  • [15:51:56] <Philippe> Usually if it is recognized you will get a /dev/ttyUSBx
  • [15:52:24] <bioster> my pci card supplies me with two ports, one is /dev/ttyS0 and the other is /dev/ttyS2
  • [15:52:36] <bioster> I'm just guessing but yours would likely show up on /dev/ttyS0
  • [15:53:16] <bioster> once your serial port is connected and linux likes it, go to: http://elinux.org/BeagleBoardBeginners
  • [15:53:39] <bioster> right under 'first interaction with the board' is a description of how to get minicom running over a serial port
  • [15:56:03] <Guest44481> okay, i'm trying atm one second
  • [15:59:07] <bioster> dmesg is probably your best bet to finding out what tty your serial port is on

  • [16:02:16] <Philippe> Guest44481, how do you mean not working? What are you trying to do?
  • [16:02:17] <Guest44481> shall i just plug in my keyboard and look if there is something new shown when i put the dmesg command?

  • [16:03:52] <Guest44481> then administrating it over the ethernet port
  • [16:04:01] <bioster> What I would do is execute the command 'tail -f /var/log/syslog' and then plug in the usb keyboard and watch what syslog says
  • [16:04:09] <bioster> dmesg is basically just replaying syslog at you
  • [16:04:20] <Guest44481> okay wait im trying this

  • [16:08:17] <Philippe> Guest44481, which beagle do you have? If I am not mistaken you need a powered USB hub for all Beagles before the XM version

  • [18:07:06] <bioster> hey there rcn
  • [18:08:21] <bioster> so I figured out the problem I was having yesterday
  • [18:08:37] <bioster> it was basically a bad card reader
  • [18:08:49] <bioster> and the 1GB card doesn't work on the -xM at all
  • [18:10:08] <rcn-ee_at_work> that's good to hear bioster, it's always some weird hardware... but the xM should boot with the same sd card..
  • [18:10:13] <rcn-ee_at_work> any noise out of the serial port?
  • [18:10:35] <rcn-ee_at_work> or does the xm work with other cards.. just not the 1GB one.?
  • [18:10:48] <bioster> yeah, the xm is working with both of the 4GB cards I have now
  • [18:10:54] <bioster> now that I'm using a different card reader

  • [18:11:28] <bioster> hey, I'm trying to get evtest working to test the user button, so I did an 'apt-get install evtest'
  • [18:11:45] <bioster> but it doesn't recognise the button on the -xM... I'm about to try the C4
  • [18:12:01] <bioster> lemme find the 1GB card, one sec
  • [18:12:33] <bioster> SanDisk
  • [18:13:03] <bioster> do you care about the microscopic lettering?
  • [18:13:27] <rcn-ee_at_work> humm, that should have worked then.. must be some cheap clone/nockoff.. couldn't really help with evtest, haven't really ever tested the buttons from userspace..
  • [18:13:47] <buZz> i find that most 'nonworking' SD cards, usually can be fixed by redoing the partitions and rewriting nearly every byte that ever was put on it
  • [18:14:15] <bioster> the 1GB card works in the C4 though
  • [18:14:54] <buZz> oh wow
  • [18:15:21] <bioster> wow?
  • [18:15:43] <rcn-ee_at_work> i'd guess it's probally since the c4 has x-loader in nand and can read the card, whereas the bootrom by it's self (xm's case) it's having issues..
  • [18:16:39] <bioster> could be
  • [18:16:51] <bioster> in any case, it's not a big deal for me, I can just use a different card
  • [18:16:59] <bioster> but it just confused issues yesterday
  • [18:17:30] * ozk (~ozk@nat/ti/x-moyboovwplsxiipz) Quit (Quit: Leaving.)
  • [18:18:01] <bioster> ok, I just used evtest on the C4 with the same image as the xM

  • [18:25:08] <bioster> oh, rcn, another guy was in here asking about the built-in network port on the -xM
  • [18:25:27] <bioster> is that working in any of the ubuntu images?
  • [18:26:43] <rcn-ee_at_work> well, the usb0 (otg Gadget) is broken in 2.6.37 so even though it shows up as s device... had a user find it works with 2.6.38-rc5, so just need to finish bisecting to find the fix.. otherwise the onboard (usb1) smsc95xx works fine..
  • [18:28:28] <bioster> hmm
  • [18:28:40] <bioster> he was also having issues with his four USB ports
  • [18:28:50] <bioster> maybe the problem was related then?
  • [18:29:18] <bioster> I tried to get my network port working, but didn't really see how
  • [18:29:27] <rcn-ee_at_work> well the 4usb/ethernet is the same usb device....
  • [18:29:42] <bioster> ah
  • [18:30:00] <bioster> well, apparently he was plugging a usb keyboard in and dmesg would show nothing
  • [18:30:06] <rcn-ee_at_work> so if the smsc95xx where to fail / not be powered, he wouldn't have any of the ports or ethernet..
  • [18:31:32] <rcn-ee_at_work> if dmesg didn't show anything, it's either broken, or not powerd.. it get's powered by probing the gpio ports and turning on the regulator.. "dmesg | grep Beagle" should say "xM"..
  • [18:31:46] <rcn-ee_at_work> otherwise it won't turn on..
  • [18:32:18] <bioster> well, my usb ports are definitely powered
  • [18:32:30] <bioster> I'll see if I can get it working
  • [18:33:00] <rcn-ee_at_work> bioster, reference: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=arch/arm/mach-omap2/board-omap3beagle.c;h=46d814ab5656c078e6fad0a013c2ce8c39e312e5;hb=HEAD#l320
  • [18:33:22] <rcn-ee_at_work> a sudo ifconfig -a followed by a sudo dhclient usb1 should get it going..
  • [18:34:13] <bioster> yup, works
  • [18:36:36] <bioster> ok, added to my interfaces file:

  • [19:32:11] <rcn-ee_at_work> then: http://pages.cs.wisc.edu/~beechung/ref/gcc-intro.html ;)
  • [19:32:57] <bioster> just to be clear, what I'm looking to do is compile on my desktop for the beagleboard
  • [19:33:18] <_av500_> aholler: ic
  • [19:33:22] <_av500_> same here
  • [19:33:50] <rcn-ee_at_work> well, native works too.. ;) your running ubuntu right? install the ubuntu cross compiler..
  • [19:34:32] <bioster> I installed gcc-arm-linux-gnueabi
  • [19:34:49] <bioster> but if that's the right package, then I guess I'm doing something wrong...
  • [19:35:04] <rcn-ee_at_work> okay.. check that it works: "arm-linux-gnueabi-gcc -v"
  • [19:35:52] <bioster> didn't give an error
  • [19:36:02] <bioster> gave me a big 'Configured with' list
  • [19:36:40] <rcn-ee_at_work> yeap, then it works..
  • [19:37:04] <aholler> compile on the beagle, it's much less painful.
  • [19:37:27] <bioster> when I replace g++ with arm-linux-gnueabi-g++, it complains: hello.o: file not recognized: File format not recognized
  • [19:38:26] <_av500_> delete hello.o and recompile it
  • [19:38:43] <bioster> already tried that
  • [19:38:43] <_av500_> and change ld to arm-...-ld too
  • [19:38:59] <bioster> hmm, ok...
  • [19:39:07] <_av500_> you need to use the whole toolchain
  • [19:39:11] <_av500_> not just g++
  • [19:39:16] <_av500_> also ld and asm etc..
  • [19:39:19] <_av500_> binutils
  • [19:39:48] <aholler> and the correct includes
  • [19:40:23] <bioster> how do I specify all that? I'm new to cross compiling... :D
  • [19:41:18] <aholler> as i said, compile nativ or buy a book. even if one book couldn't be enough to explain all the beauties of cross compiling.
  • [19:42:33] <djlewis_> hello.c might take a millisecond to compile natively :)
  • [19:42:53] <bioster> :P
  • [19:42:55] <Norritt42> bioster: Hi may i tip you about Eclipse and narcisuss
  • [19:43:24] <bioster> Has Eclipse gotten better in the last 8 or 9 years? :D
  • [19:43:28] <djlewis_> this should be fun
  • [19:43:47] <_av500_> eclipse is a compiler now?
  • [19:43:53] <Norritt42> I'm a newbe to and are curently seting up a development enviorment and yes eclipse works fine for me
  • [19:44:20] <aholler> most avr-develpment-packets are today for windows and are coming with eclipse...
  • [19:44:33] <ds2> cross compiling is easy
  • [19:44:45] <ds2> set your path to pull in the unqualified version of the xcompiler and away you go
  • [19:44:55] <Norritt42> every thing is esy when you know how to do it
  • [19:44:57] <Norritt42> :)
  • [19:45:12] <ds2> using the qualified names just lets you have a chance of using the native compiler
  • [19:45:18] <rcn-ee_at_work> ds2 it's actually already in the path, so that's part is easy. ;)
  • [19:45:28] <ds2> then g++ should work ;)

  • [23:37:40] <nndhawan> djlewis_: I tried this, it does not seem to work. NP here are your answers: C4, Angstrom linux 2.6.32, no hub (I do have one not connected though)
  • [23:37:54] <nndhawan> djlewis_: I was going to try the powered hub cause I heard that might work
  • [23:38:11] <djlewis_> go for the powered hub next
  • [23:38:14] <nndhawan> k
  • [23:38:18] <djlewis_> does lsusb tell you anything?
  • [23:38:36] <djlewis_> does dmesg tell you anything?
  • [23:39:57] <nndhawan> lsusb gives following result: Bus 001 Device 001: ED 1d6b:002 Linux Foundation 2.0 root hub \n Buss 002 Device 001: ID 1d6b:002 Linux Foundation 2.0 root hub
  • [23:40:15] <djlewis_> sounds like only the BB usb
  • [23:40:58] <nndhawan> dmesg seems to not register the device (there was no change between the outputs when I removed the usb dongle and reinserted it), I used this command: dmesg | grep usb
  • [23:48:30] <ds2> WiFi USB dongles just work
  • [23:48:33] <xerebz> djlewis_: i'm using ubuntu 10.10 on the beagleboard-xM
  • [23:48:38] <ds2> are you on the EHCI or the MUSB port?
  • [23:49:30] <nndhawan> ds2: I think EHCI is what its called
  • [23:49:37] <nndhawan> ds2: what is MUSB?
  • [23:49:59] <ds2> Okay, is it a USB High Speed dongle?

  • [23:52:31] <xerebz> and i'm guessing musb == otg
  • [23:53:18] <xerebz> btw what's the easiest way to cross compile for the beagleboard xm on an ubuntu laptop
  • [23:53:37] <rcn-ee> xerebz, your on the xM so the 4port connector is behind a usb 2.0 hub so you can connect any device..
  • [23:54:00] <xerebz> yeah i was just answering his question, my usbs work fine :D
  • [23:54:30] <rcn-ee> xerebz, on an ubuntu machine, linaro's arm cross compiler is an apt-get away..
  • [23:54:34] <nndhawan> ds2: I am not sure how to answer the MUSB question, in any case it says that is USB Spec 11 compliant so I am not sure if its a 2.0 high speed
  • [23:54:53] <nndhawan> yea I also like xerebz other question for cross-compiling
  • [23:55:20] <rcn-ee> sudo apt-get install gcc-4.5-arm-linux-gnueabi or 4.4
  • [23:55:21] <ds2> if it is 1.1, then you will need a hub.
  • [23:55:35] <nndhawan> xerebz: I have been able to CodeSourcery and its arm-none-gnueabi-gcc compiler to cross-compile a simple program for my beagleboard
  • [23:56:05] <xerebz> nndhawan: just from experience, most usb don't work on that ehci usb2.0hs is such a small subset of usb devices
  • [23:56:17] <ds2> your lsusb do not show a hub.
  • [23:56:21] <xerebz> nndhawan: i would get a powered usb 2.0 and attach it to the otg
  • [23:56:33] <rcn-ee> good point, it's only showing usb2.0..
  • [23:57:07] <nndhawan> how can I tell if my powered hub is usb 2.0
  • [23:57:18] <nndhawan> it does not say it anywhere on it
  • [23:57:28] <ds2> toss it in a sniffer and see if you can see TT's when a USB 1.x device is plugged in? :D
  • [23:57:32] <djlewis_> if it is fairly new it most likely is
  • [23:57:42] <xerebz> nndhawan: probably isn't.. does it add anything on the lsusb when you connect it?
  • [23:57:52] <ds2> djlewis: I would not say that... I can go buy a $1 hub today that is not USB 2.0 ;)
  • [23:57:59] <xerebz> nndhawan: and it could be usb 2.0 but not high speed i had one like that
  • [23:58:16] <nndhawan> djlewis_: :( no I didn't see anything when I used lusb
