  • [00:00:32] <mru> now stop complaining
  • [00:00:36] <unsolo_> hehe
  • [00:00:45] <mru> what would you even do with the bare chip anyway?
  • [00:00:55] <unsolo_> create a small scale product
  • [00:00:57] <mru> it's not like you'd be soldering it at home
  • [00:01:20] <unsolo_> there are companies as i mentioned that need something inbetween those numbers.
  • [00:01:31] <unsolo_> ordering a som is not a good enough alternative
  • [00:01:35] <unsolo_> they need the chip
  • [00:01:57] <unsolo_> and the oportunity to order a single replacement chip if needed
  • [00:02:16] <unsolo_> all those companies will stay away from the omap4xxxx
  • [00:02:22] <unsolo_> which is why i dislike it
  • [00:02:25] <unsolo_> its like omap2
  • [00:02:35] <unsolo_> anyhow lets leave it at that

  • [00:03:08] <mru> so why did you say a9 sucks?
  • [00:03:12] <unsolo_> but im waiting hoping that TI does another omap3 stunt on the A15's
  • [00:03:23] <mru> if you really meant that TI's sales model for omap4 sucks
  • [00:03:32] <mru> which I _might_ agree with to some extent
  • [00:03:52] <unsolo_> mru: because i suck at making a point ;)
  • [00:04:30] <unsolo_> btw is there a dsp in the 4440 ?

  • [00:09:35] <unsolo_> btw the dsp in the xm has quite the computing power
  • [00:09:57] <unsolo_> is there any setup that allows you to code for them w/o pushing money to TI ?
  • [00:09:57] <mru> yeah, it's a shame it's more or less impossible to program it
  • [00:10:00] <Loa_> Thanks unsolo, is gdb able to demonstrate the bb peripherals' registers content or it just report the processor stack state
  • [00:10:23] <unsolo_> Loa_: its a computer not a microcontroller
  • [00:11:13] <unsolo_> so gsb will report what your userspace application is up to
  • [00:11:34] <unsolo_> if its kernel space you need a jtag or some other form of linux kernel debugger

  • [00:41:35] <jstearns74> Hey everyone, I am trying to use Narcissus to build a new image for my beagleboard-xm. When I try to use the latest kernel [advanced: release: core-eglibc] I end up with MLO, uImage, & u-boot.img in my boot dir. I was expecting u-boot.bin. I can't get things to boot with the u-boot.img file. Any ideas?
  • [00:42:42] <unsolo_> jstearns74: the MLO needs to go first
  • [00:42:54] <unsolo_> as it is texas instruments xloader
  • [00:43:12] <unsolo_> that will load your uboot.img file (unless someone messed up)
  • [00:43:48] <unsolo_> the uImage is your linux kernel and thats next on the menu
  • [00:43:59] <jstearns74> hum... I tried that. When the bb-xm starts to boot, it spits out something about looking for u-boot.bin.
  • [00:44:12] <unsolo_> cool
  • [00:44:18] <jstearns74> should i not include the .img file?
  • [00:44:19] <unsolo_> have you tried renaming uboot.img
  • [00:44:29] * unsolo_ hopes so
  • [00:44:33] <jstearns74> yes. i tried that.
  • [00:44:39] <unsolo_> and it failed ?
  • [00:44:44] <jstearns74> yup.
  • [00:44:58] <unsolo_> did you replace the MLO on your flash ?
  • [00:45:25] <jstearns74> yes. i replaced the MLO on the flash at the same time as I copied over the uimage.
  • [00:45:39] <unsolo_> interesting
  • [00:46:05] <unsolo_> btw why did you replace MLO and u-boot.bin ?
  • [00:46:28] <unsolo_> since they obviusly have very little to do with the linux kernel it self they just load it
  • [00:47:10] <XMPPwocky> http://pastebin.com/DiTA6DM2 So, should this code work as described?
  • [00:47:17] <jstearns74> I just copied them over together after I downloaded the image from narcissus.
  • [00:47:29] <unsolo_> hmm
  • [00:47:32] <XMPPwocky> oops
  • [00:47:52] <unsolo_> jstearns74: sorry no idea maybe its compressed ?
  • [00:47:56] <XMPPwocky> http://pastebin.com/6zzFjM7y this, rather
  • [00:47:59] <jstearns74> BTW - i get u-boot.bin when I select the stable version of the kernel. I get u-boot.img when I select the latest...
  • [00:48:12] <unsolo_> file u-boot.img
  • [00:48:13] <jstearns74> thats what I thought. was hoping someone else has seen this before.
  • [00:48:56] <jstearns74> i will continue working on it and post something if i find an answer. its completely possible I am retarded and just messed something up.
  • [00:49:08] <unsolo_> did you try file
  • [00:49:13] <jstearns74> no, but i will.
  • [00:49:49] <XMPPwocky> er.. crap. http://pastebin.com/3KwBvrRy (at least it assembles)
  • [00:49:55] <unsolo_> well if its some form of compressed image that would make it clear why A MLO is looking for u-boot.bin and B you have a u-boot.img

  • [01:01:29] <XMPPwocky> sure, but if I don't have to right now, I'd rather not
  • [01:01:33] <unsolo_> then bang the bytes out
  • [01:01:33] <jay6981> haha
  • [01:02:09] <jay6981> the mask rom is nice enough to hand off a clock tree that'll work with 64k sram and the uart

  • [01:02:36] <unsolo_> ftdi
  • [01:02:39] <jay6981> or mmc
  • [01:02:40] <unsolo_> you have a bone
  • [01:02:47] <jay6981> i made my own "MLO"

  • [01:03:02] <XMPPwocky> unsolo_: JTAG?
  • [01:03:21] <unsolo_> openocd + eclipse + ftdi (jtag) and you can break code in the 64KB
  • [01:03:26] <unsolo_> even load it
  • [01:03:29] <unsolo_> jump it
  • [01:03:30] <jay6981> the mask rom will allegedly load things straight from uart into sram but I never managed to make it work
  • [01:03:33] <unsolo_> and all kinds of fun

  • [13:27:55] * _av500_ braces
  • [13:28:22] <mik__> I've installed ubuntu 11.10 in my beagleboard xm. I am trying to play audio but although I don't getany error I don't get any audio out of it...
  • [13:28:29] <mik__> does anyone has any pointer?
  • [13:28:33] * dENNES (~Adium@192.38.36.16) has joined #beagle
  • [13:28:45] <mik__> I've tried to use aplay, or alsa or python audio, or paython alsa...
  • [13:28:56] <_av500_> #ubuntu-arm might have pointers
  • [13:29:03] <mik__> it appears like if it is playing... but I don't hear anything
  • [13:29:06] <_av500_> are you suing the official ubuntu or rcn?
  • [13:29:11] <_av500_> using
  • [13:29:13] <mik__> oh... is this chat only for Angstrom?
  • [13:29:16] <_av500_> no
  • [13:29:29] <_av500_> but there is a dedicated chat for ubuntu on arm

  • [13:29:46] <mik__> thanks
  • [13:30:04] <_av500_> are you using official ubuntu or rcn?
  • [13:30:40] <mik__> ehmm... not sure, I followed instructions in here: http://elinux.org/BeagleBoardUbuntu#Oneiric_11.10
  • [13:30:48] <mik__> is it officila?
  • [13:32:02] <_av500_> if you got the image from ubuntu.com then yes
  • [13:32:48] <_av500_> and that page mentions ubuntu-arm too
  • [13:32:57] <_av500_> tried amixer?
  • [13:33:03] <mik__> just noticed: the link seems to point to rnc ....
  • [13:33:20] <mik__> rcn-ee.net
  • [13:33:26] <_av500_> thats rcn's private build
  • [13:33:32] <_av500_> he is here sometimes
  • [13:33:37] <_av500_> not atm
  • [13:33:39] <_av500_> tried amixer?
  • [13:33:42] <mik__> ah!
  • [13:33:48] <mik__> no, I will try amixer
  • [13:34:07] <mik__> and maybe an official build then. Thanks for clarifying this

  • [13:40:29] <mik__> @av500 another question if you don't mind: I presume the RobertCNelson is another private build then (just found in the same poage). Point is: is the official ubuntu image not good enough or is just that people need different things?

  • [17:54:30] <kosta> Hi All! I need help with the beaglebone, as I'm completely stuck. All I need is an any Linux distribution on Beagle that has a) userspace access to analog input and b) userspace access to SPI. Default Angstrom image does have access to ADC, but no SPI. When I try to rebuild kernel (or to use Ubuntu distro), I got SPI access, but no ADC. I'm by no means kernel developer, all I need is to develop application, and not to dive into kernel d
  • [17:54:41] <kosta> Is there ANY distro that has both?
  • [17:55:00] <mranostay> build both into the kernel?
  • [17:55:47] <jsabeaudry> kosta, let me check I think arch might have both
  • [17:55:55] <kosta> Have no idea how to do this. Well, I was able to find out magic commands to build SPI into kernel, but I have no idea what to use for ADC

  • [17:59:42] <mranostay> i think that is an american term
  • [17:59:43] <jsabeaudry> Any idea which SPI mode you need kosta?
  • [17:59:55] <kosta> I used instructions from archlinuxarm.org. When I build an image, it had no ains in platform/tsc. May be I was looking in a wrong place?
  • [18:00:07] <mranostay> since most of the crap people drink here comes from huge hundred thousand litre vats
  • [18:00:36] <jsabeaudry> kosta, just download the prebuilt and update with pacman -Syu
  • [18:01:07] <koen> kosta: as soon as some actually answers when being asked the polarity/speed question, we can't provide spidev in the default kernel
  • [18:01:11] <jsabeaudry> kosta, Here is in /sys/devices/platform/tsc/ain1
  • [18:01:27] <kosta> jsabeaudry - just any. I'm very novice, and got taks at work to communicate with an SPI device. With no docs or samples all that I was able to find is to read/write to /dev/spi*. Well, default Angstrom has not such files, i.e. no usedspace SPI

I'm writing in C/C++, and in the end all I need is some function like writeToSPI(data, options). Doing it via file i/o seems like lots of overhead. May you can point me to right direction? The only example I was able to find in this regard was some kernel module example, and want to avoid that as my knowledge of Linux internals is close to zero
  • [18:46:35] <kosta> BTW, similar function for analog input would be also nice:) I made it work via file i/o, but it seems too cumbersome approach

  • [18:47:47] * prpplague looks
  • [18:47:49] <alan_o> kosta: In order to do SPI from userspace (the right way), you'll need to attach the spidev driver to one of the SPI ports. This requires a kernel modification and re-build.
  • [18:47:50] <GrueMaster> Meh, that is kernel next. I am using 3.0 for Oneiric, 3.2 for Precise.

  • [19:11:13] <kosta> jsabeaudry: what do mean by "spidev approach"? Access via file?
  • [19:11:41] <dwery> kosta: you can use file I/O on the spidev device.
  • [19:11:55] <jsabeaudry> kosta, Yes, access using a driver named "spidev" that will expose a device file typically in /dev/
  • [19:12:20] <kosta> Like /dev/spi* ? Yes, that what I meant: it is simple, but too inefficient
  • [19:12:21] <dwery> kosta: http://www.kernel.org/doc/Documentation/spi/spidev_test.c
  • [19:12:44] <jsabeaudry> kosta, How is it inefficient?
  • [19:13:33] <kosta> jsabeaudry: well, you write file, then process should read the file, parse it, call driver....blah-blah-blah - too many intermediate steps
  • [19:14:26] <dwery> kosta: it will do just fine, trust me. you only other option is to write a kernel driver

  • [19:14:57] <kosta> So it is either file i/o or kernel driver, right?
  • [19:15:14] <kosta> I was thingking may there is some other way that I just don't know about
  • [19:15:22] <jsabeaudry> kosta, Your assumptions are false, communicating with a char device does not involve what you think it does
  • [19:16:05] <dwery> kosta: yes
  • [19:16:21] <dwery> kosta: which device are you talking to?
  • [19:16:23] <kosta> jsabeaudry: I'll take your word for that :) Again, my knowledge of Linux internal is zero, so my assumption might be wrong
  • [19:16:35] <kosta> dwery: bone
  • [19:17:12] <jsabeaudry> kosta, http://en.wikipedia.org/wiki/Device_file
  • [19:17:21] <jsabeaudry> kosta, Is this part of a school project?
  • [19:17:22] <dwery> kosta: and the other device?
  • [19:18:09] <alan_o> kosta: yes, what jsabeaudry said. It's not a file like a file on a filesystem that contains text or something. It's a special file which talks directly to a kernel driver. In this case spidev.
  • [19:19:20] * bradfa (~bradfa@173.225.52.244) has joined #beagle
  • [19:20:01] <kosta> I see, so it is more like memory map, right?
  • [19:20:03] <jsabeaudry> kosta, try reading the entire contents of the file /dev/urandom, let me know if it fits on your hard drive
  • [19:20:16] <alan_o> kosta: no. It's not a memory map
  • [19:20:28] <kosta> Stream?
  • [19:20:40] <alan_o> kosta: (however there is a /dev/mem device which _is_ a memory map)
  • [19:21:06] <alan_o> kosta: it's an interface
  • [19:21:07] <mru> jsabeaudry: it fits in my /dev/null
  • [19:21:13] <alan_o> Did you read the wikipedia link above?
  • [19:21:21] <jsabeaudry> mru, ;)
  • [19:21:23] <kosta> Yes, briefly
  • [19:21:36] <kosta> Looks like a stream
  • [19:21:56] <mru> alan_o: there are other memory-mapped dev files
  • [19:22:14] <mru> like /dev/fb
  • [19:22:59] <alan_o> kosta: It's basically a direct interface to a driver (in this case a character device). When you call write() on the /dev/spidev* node, it calls the write() funciton in the spidev driver. What that write() (driver) function does is up to the driver, and varies from driver to driver. In the case of spidev, it will clock data out the SPI port.
  • [19:23:32] <alan_o> mru: true, some device drivers are memory mapped. It's basically all up to the driver, how it's appropriate for it to be implemented
  • [19:23:45] <kosta> alan_o: thank you! Now that is very clear explanation
  • [19:24:18] <kosta> Actually, this is part-time job project. I'm totaly noob in linux/embedded, coming from many years of strictly Win env :)
  • [19:24:36] <alan_o> since spi devices are datagram oriented (each "packet" is delimited by chip select going high to low and back again, for most devices, yes there are exceptions), spidev can be thought of as that kind of device.
  • [19:25:26] <alan_o> kosta: in the spidev example program, look at the transfer function. This will do a bi-directional transfer (which is what SPI does all the time).
  • [19:26:21] <alan_o> kosta: since read/write aren't appropriate for this, it uses an ioctl(), so that it can pass both an input and output buffer. I think that kind of paradigm will probably be your workhorse from userspace.
  • [19:28:28] <kosta> alan_o: yeap, this is exactly what I was going to do. I was just wondering how efficient it would be. Now with your excellent explanation about how it interfaces with the driver, I don't worry anymore
  • [19:29:34] <alan_o> kosta: also, in default configuration, d0 is MISO and d1 is MOSI. That took me a long time to figure out and I still don't quite know why or how. (I should have just tried it).

  • [19:31:06] <alan_o> which reminds me that I wanted to ask why and how that works.... Any takers here? d0 and d1 can both be set to MOSI or MISO on the am335x. However, I can find nothing in the kernel which sets these, and according to the TRM, it shows that the power-on-reset values of the register bits that set the direction both default to output, so I can't see how it works at all (but it does).

  • [21:41:35] <SilicaGel> Patch the kernel to chagne a device name! haha
  • [21:42:08] <XMPPwocky> so I should make a section in my linkscript just for the interrupt vectors?
  • [21:42:15] <SilicaGel> I find tha tif one takes the time to learn udev, it really grows on you

  • [21:44:08] <mru> symlink seems far simpler and easier to maintain
  • [21:44:59] <SilicaGel> yeah. Just add a udev rule to make the symlink, and have it trigger off of the detection of the device
  • [21:45:26] * ds2 shakes a fist at google for pushing out bad trees

  • [21:52:34] <ds2> there are 2 ways of doing it, some mfgs use a MAF and others use a MAP sensor
  • [21:52:40] <SilicaGel> so i guess it could know the air flow if it knew the aperature and the ambient pressure?
  • [21:52:49] <ds2> are you looking at the OBD stuff?

  • [23:44:55] <alan_o> XMPPwocky: nice work. So much can be learned by dropping it down one layer (or in your case a few layers).
  • [23:45:50] <jay6981> he's still using uboot to init the machine :P
  • [23:47:20] <alan_o> Hey, there's always more layers to go :) I saw a slashdot thread once that started from something like "you write in an interpreted language?" that went all the way down through "you use other peoples's CPUs?" to "what, you don't mine your own ore?"
  • [23:47:46] <jay6981> well, being a software guy i generally draw the line at RTL
  • [23:48:35] <alan_o> That's a good cutoff point. Although I'd like to know some about FPGAs.......
  • [23:48:41] <alan_o> Not enough hours in the day
  • [23:48:58] <jay6981> indeed
  • [23:49:08] <jay6981> i'll learn it soon enough I'm sure
  • [23:49:10] <ds2> mkhours
  • [23:49:19] <jay6981> until then I just go bug the RTL guys
  • [23:49:46] <alan_o> alan@ato:~$ mkhours
  • [23:49:48] <alan_o> mkhours: command not found
  • [23:49:50] <alan_o> dang it.
  • [23:50:02] <ds2> /usr/local/sbin/addhours
  • [23:50:04] <ds2> ;)
  • [23:50:16] <alan_o> /usr/local ... .burns me every time
  • [23:51:24] <ds2> mkhours(8)
  • [23:51:24] <alan_o> Actually, that's in my path on Ubuntu. Back when I ran RedHat, it drove me insane that it wasn't in the path, but that autotools always wanted to put software there by default. Sure you can override either one, but it seemed to me back then that defaults should work together :(
  • [23:51:27] <ds2> BUGS
  • [23:51:43] <ds2> Run time of mkhours is 1+parameter number of hours long.
  • [23:51:44] <ds2> :)
