  • [00:00:28] <geist> sorry, I'll shut up about errata. As far as I can tell these are identical...
  • [00:00:46] <geist> yeah, has the mmc multiblock dma thing too
  • [00:00:47] <geist> rad!
  • [00:01:32] <mru> and it appears to be fixed in es3.0
  • [00:01:41] <geist> yep, is in 3430 as well
  • [00:01:46] <geist> not the usb one though
  • [00:01:50] <mru> no
  • [00:02:02] <geist> i have a little errata to report to TI actually, but hven't completely verified it.
  • [00:02:17] <geist> the double buffering in the musb part seems to fail
  • [00:02:25] <geist> it'll occasionally go nuts and screw up the fifio
  • [00:02:27] <mru> I'm a bit surprised by how few things are reported as fixed in 3.0
  • [00:02:44] <geist> since essentially no one uses double buffering, i'm not surprised it hadn't been seen

  • [08:52:41] <koen> beagle is more succesfull than I expected :)
  • [08:53:46] <Beagle0> hi, I got my beagle two days ago and I've followed the BeagleBoardBeginners wiki and got it all working with angstrom demo from an sd card
  • [08:54:27] <Beagle0> i guess it's time for the more scary step, setting up the on board nand with a kernel+filesystem?
  • [08:56:49] <Beagle2> they were actually 2054 behind. So It starts to be great success.
  • [08:57:01] <ldesnogu> koen: mru found es3.0 is r1p3 (hoping the Cortex-a8 ID is correct); r1p3 fixes the NEON bug

  • [09:01:03] <koen> Beagle0: on the beagle nand is a lot slower than sd, so not many people are using it
  • [09:01:11] * koen should try ubifs soon

  • [12:18:45] <Beagle0> ok, i've been very lucky with my serial port coms, i've never had any problems so i don't have vast exp with debugging
  • [12:19:08] <mbuf> Beagle0: now i am trying with gnome-terminal and it is ok; previously it was with Eterm
  • [12:19:56] <Beagle0> ehm. ok. i was using xterm...so a locale issue then?
  • [12:20:17] <mbuf> Beagle0: probably
  • [12:20:22] <mbuf> Beagle0: now its ok; time to explore more

  • [13:39:53] * koen wonders how much patching maemo5 needs to crosscompile
  • [13:40:07] <koen> and I also wonder how much closed-source crap it depends on

  • [13:45:57] <GeneralAntilles> Though the talk he gave at OSiM yesterday was promising.

  • [16:28:28] <piller> Hi, just got my beagleboard, hooked it up, digital lcd monitor screen shows picture and "beagleboard.org" and that's it.
  • [16:28:59] <GeneralAntilles> Now to get a serial console.
  • [16:29:10] <piller> I've got a usb hub, usb keyboard, usb mouse, does not seem to do anything
  • [16:29:21] <geist> it's sitting in the bootloader
  • [16:29:27] <geist> you need a serial console
  • [16:29:29] <GeneralAntilles> It doesn't come bundled with a real OS.
  • [16:29:37] <piller> how do I get the serial console?
  • [16:29:59] <piller> I have to make up a cable, use null modem to pc?
  • [16:30:09] <GeneralAntilles> You'll need an IDC10 to DB9 cable (AT/Everex "straight-through" type), a null modem cable and maybe a USB-serial adaptor.
  • [16:30:11] <geist> should be mentioned on the wiki, but in short you need to hook a serial cable up to the 10 pin serial header next to the power connector
  • [16:30:21] <GeneralAntilles> http://www.pccables.com/07120.htm
  • [16:30:42] <piller> OK, I'll get the cable sorted out, but then what?
  • [16:30:56] <GeneralAntilles> Then you'll need to load something to boot onto an SD card.
  • [16:31:16] <GeneralAntilles> and tell the bootloader to boot it over the serial console.
  • [16:31:25] <GeneralAntilles> http://www.angstrom-distribution.org/beagleboard-demo-image-available <- probably a good one to start with.
  • [16:31:33] <piller> Ahhh, I thought it came with linux loaded into flash or something
  • [16:31:43] <geist> no, doens't have that much onboard flash
  • [16:31:56] <GeneralAntilles> Do you have the appropriate OTG adaptor for USB?
  • [16:32:20] <piller> OK, thanks, I'll get working on the serial cable and then check the link.
  • [16:33:44] <piller> I bought the recommended usb cable from digikey, it has a mini A on one end that connects to beagle, the other end plugs into my usb hub, is that right?
  • [16:33:56] <GeneralAntilles> Yeah, that's right.
  • [16:34:28] <piller> Great, so I've got to get a serial connection to the console working first, then go from there.
  • [16:38:03] <Crofton> jkridner_, can you update the bug with the new information
  • [16:38:58] <pbrook> How easy is it to get stuff to boot without a serial console? I guess rebuild uboot with a fixed boot command rather than using what's saved in flash?

  • [16:45:50] <geist> oh hey, it's richardw
  • [16:45:58] * geist sees his name in a lot of TI code :)
  • [16:46:25] <richardw> geist, yea in some from a while back
  • [16:46:37] <richardw> still some today but less time...
  • [16:47:45] <geist> been battling shipping something on 3430, so have been kind of deep into omap stuff lately
  • [16:48:20] <richardw> there is a lot inside the chip... easy to get lost.
  • [16:48:44] <geist> yeah, power management especially. we suggested that maybe next time TI shouldn't try to make the silicon so 'smart'
  • [16:51:03] <richardw> software does have to do a lot of lifting there. You get something like that when you target 1ghz + new process and want to keep a path to uA idles. Its faster, with more features, but the want of a similar power envelope
  • [16:51:23] <peter|work> why we get the following message "prcm_set_clock_domain_state : Pre-condition not met."
  • [16:51:34] <prpplague> koen: ping
  • [16:51:55] <prpplague> geist: what kind of product?
  • [16:51:57] <geist> richardw: actually it's the opposite part. software has to do a lot of lifting is great, but then the hardware tries to do a lot for you, and when it doesn't work it's really frusterating to debug
  • [16:52:09] <geist> ie, 'i tried to go to sleep, but someone kept me from doing it'
  • [16:52:12] <prpplague> geist: we are getting geared up for a handheld using the 3430
  • [16:52:13] <geist> well, gee, that's not real helpful
  • [16:53:30] <richardw> geist, I find lauterbach really helpful here... It breaks out all registers. With some well placed stop points you can somewhat quickly fix many mystery, you start from PRCM status and move out from the middle in your debug.
  • [16:53:33] <geist> prpplague: similar, though since it's kind of secret i shouldn't say much more
  • [16:53:51] <prpplague> geist: np
  • [16:53:52] <geist> richardw: yep, though once you're into form factor, jtag becomes a lot less useful
  • [16:54:13] <geist> and jtag doesn't help you as you go into deep sleep, since you have to power off that part of the chip too
  • [16:54:33] <geist> but thankfully TI has the serial bypass through the 4030 that is sooo handy
  • [16:54:45] <prpplague> geist: mind if i ask who you work for?
  • [16:55:04] <geist> shouldn't say yet
  • [16:55:10] <prpplague> richardw: i'm working on adding icepick support to openocd, but it is slow going
  • [16:55:19] <geist> though you can google around and probably find out :)
  • [16:55:23] <prpplague> i see
  • [16:55:25] <richardw> perter|work, that lets you know a driver has released its clock but it has not internally moved into a proper state before doing it. If you leave status around the module won't drop its hardware dependencies and you end up missing sleep, if you put a BUG() in your paths you can find the offender. Usually its some driver which is not follow specs
  • [16:57:33] <geist> prpplague: and no, i still dont work for apple, I just haven't updated my web page :)
  • [16:57:41] <richardw> geist, there is magic possible for debug. With the right setup, the icemelter in wakeup domain can wake the emulation domain and that domain can source clocks for debug. Even with the fancy path (which not many support) you can do save/restore context of coresight registers and you get more then you think you can.
  • [16:58:00] <geist> either way, it's still not useful once you have a form factor device. no jtag
  • [16:58:07] <prpplague> geist: yea i wasn't looking, but i was guessing you work for the gumstix folks
  • [16:58:12] <geist> it's all debugging via kprintfs
  • [16:58:18] <geist> prpplague: nah
  • [16:58:59] <sakoman_> prpplague: I wish he did! It would be nice to have help :-)
  • [16:59:05] <prpplague> hehe
  • [16:59:07] <geist> richardw: anyway, i guess sw people just generally prefer there to be a bunch of bits to whack, let sw take care of the deps, and wish hardware didn't try to do so much
  • [16:59:15] <geist> sakoman_: hah
  • [16:59:30] <geist> i worked for sakoman_ years ago
  • [16:59:39] <Crofton|work> <pb_> they should be installed in /usr/lib/gcc/xxx/yyy/
  • [16:59:43] <geist> generally a benevolent tyrant
  • [16:59:48] <Crofton|work> heh
  • [16:59:53] * Crofton|work speculates

  • [17:00:49] <prpplague> richardw: is the lauterbach config file for the omap3xxx stuff publically available?
  • [17:01:20] <richardw> geist, you need to always push hardware guys to have a debug board or a header, some edge connector can be a savior.
  • [17:02:50] <khasim> I am looking for a caption for beagleboard.org - in just 4 to 5 words, can some one give a thought
  • [17:03:23] <geist> nah, serial is all I need. :)
  • [17:03:34] <geist> haven't fired up a jtag in 6 months or so
  • [17:03:41] <geist> and we're too cheap to buy lauterbachs
  • [17:03:56] <richardw> geist, i have been frustrated for sure on this many times... Software today can't control things fast enough to get active mode power savings with out hardware help. If you set it up right its the difference between 10mW operation and a 90mW one for some codec operation. Now, you do need to put it into context with the rest of you system. If your WiFi driver is drawing 500mW then maybe killing your self somewhere else over 20mW doesn't
  • [17:03:56] <richardw> seem so big. Its about use case targets and the usage profile...
  • [17:04:23] <geist> if your wifi is using 500mW then you go beat on the wifi guys until they drop to 0
  • [17:04:35] <geist> then it's your problem again :)
  • [17:04:49] <richardw> sometimes
  • [17:05:06] <geist> well, if they dont drop to 0 then you can't ship and you go find another job
  • [17:05:18] <geist> so you always assume you're the longest pole in the tent
  • [17:05:51] <geist> but yeah, it's good to have perspective
  • [17:06:30] <prpplague> geist: yea the cost of the bdi and lauterbach stuff is what is driving the sales of the flyswatter
  • [17:06:31] <geist> right now i'm working on getting the omap3 under 100mA in the bootloader (for trickle charging on a non emuerated usb bus)
  • [17:06:46] <geist> that's a bit of a stretch, as soon as you fire up that core power domain the omap is a piggy
  • [17:06:52] <prpplague> geist: as soon as we finish up with the icepick support for openocd, we'll be rev'n the design
  • [17:07:51] <prpplague> geist: interesting, how much is the core drawing, just with the bootloader running?
  • [17:07:57] <jkridner|work> geist: assume you have all the clocks off that you can?
  • [17:08:08] <geist> yep, and the main cpu down to 125Mhz
  • [17:08:19] <geist> it's at about 90 right now, idling
  • [17:08:32] <geist> getting the core domain off next is the next thing, but sadly the uart is in that domain so i'll lose it
  • [17:08:45] <geist> so will have to go blind from then on out
  • [17:08:59] <jkridner|work> or go JTAG?
  • [17:09:05] <geist> can't. form factor unit
  • [17:09:40] * jkridner|work wishes everyone would put a JTAG header on their form factor units. :)
  • [17:09:49] <prpplague> hehe
  • [17:09:53] <jkridner|work> when used out-of-the-case.
  • [17:09:53] <geist> *shrug*. i've gotten away without jtag for years
  • [17:09:58] <geist> keeps you on your toes
  • [17:10:01] <prpplague> jkridner|work: we put pads on all of our stuff
  • [17:10:23] <geist> as long as i have a das blinkinlight i'm okay
  • [17:10:31] <jkridner|work> do you have local storage/logging?
  • [17:10:43] <prpplague> geist: indeed there are some very diverse opinions about jtag, i know alot of folks that get away without using jtag for all there dev
  • [17:10:51] * jkridner|work likes blinkly-lights. :)
  • [17:11:29] <geist> jkridner|work: yep. I can see the power usage, so for now i'll just test by going into the state and come out of it 10 seconds later or so
  • [17:11:29] <geist> and then i can observe what it went to
  • [17:11:33] <geist> and of course if it doesnt come out, then I gotta fix that :)
  • [17:11:33] <prpplague> blinky lights don't always make it easy to diagnose hardware issues
  • [17:11:39] <mru> well-written code is easy enough to manage without jtag
  • [17:11:45] <geist> exactly
  • [17:11:55] <prpplague> mru: code yes
  • [17:11:59] <mru> jtag is most useful when debugging crazy code written by others
  • [17:12:02] <geist> back in the danger days shipping on omap1 we didn't even have jtag
  • [17:12:06] <geist> no one had though to get one
  • [17:12:13] <geist> we wrote all of that code blind

  • [17:12:34] <geist> omaps are particularly easy to hack on without jtag since they always have that built in loader
  • [17:12:47] <prpplague> geist: yea, i've noticed that
  • [17:12:55] <geist> the only time i really use jtag is to break into a cpu i can otherwise not get code onto
  • [17:13:21] <prpplague> i mainly using it during initial board bringup and design verification
  • [17:13:23] <geist> and it's occasionally useful when your kernel goes off in the weeds and you really just can't figure it out

  • [17:14:15] <prpplague> geist: yea as long as you have a uart and plenty of printk's you can usually work thru kernel issues
  • [17:14:34] <geist> yep. only time it becomes a pain is for deep power management
  • [17:14:44] <geist> but i've found that jtag becomes a lot less useful then too
  • [17:14:57] <geist> like when you put the cpu into non-retention, etc
  • [17:15:14] <prpplague> geist: yea, thats kind of why the next gen of jtag stuff using JRC's will help
  • [17:15:22] <geist> liek when you're trying to get the whole shebang under 2 or 3 mA
  • [17:15:32] <geist> which thankfully you can actually do with omap3, you just have to pull a lot of strings
  • [17:16:41] <geist> anyway, the 100mA problem I have now is extra tricky because i actually have to get the system under 100mA worst case, not just average case
  • [17:16:59] <geist> and that's while runing the musb part, which seems to pull 30mA or so by itself

  • [18:52:15] <prpplague> assuming it is a true SD card

  • [18:52:35] <piller> support both 4 and 8 bit cards, but 8 Bit cards are 1.8V only and the boot mode supports a
  • [18:52:35] <piller> 3V card. In order to boot from MMC/SD the card must be a 3V 4 bit card.
  • [18:53:11] <vlad_> huh, I didn't know that

  • [20:34:14] <jkridner|work> debug the ASoC code in the kernel or use the validation 2.6.22 kernel ALSA driver.

  • [20:36:11] <jkridner|work> I'd suggest trying to build some momentum for supporting an encoder by taking on some specific problems and notifying people on the mailing list.
  • [20:36:37] <jkridner|work> a specific problem could be working out a driver for a particular encoder, but that may be beyond your current skill set.
  • [20:36:57] <jkridner|work> (best to start with an encoder already supported by Linux on other platforms)
  • [20:36:58] <Beagle9> yeah, it definately is
  • [20:37:02] <BThompson> what you were saying about audio just a bit ago, does beagle have problems decoding audio and displaying at the same time? I found that starting the ALSA driver on the evm kills the dvi output....
  • [20:37:19] <Beagle9> im just a hobbiest
  • [20:37:46] <Beagle9> thanks for the help

  • [20:37:49] <jkridner|work> BThompson: I haven't seen that problem on the EVM with the GStreamer demo.
  • [20:38:34] <jkridner|work> I hate to scare people away like that, but I don't want them to get too frustrated either. oh, well. hopefully he'll bite of some part of the challenge.
  • [20:38:35] <BThompson> it must be some driver level issue, and it seems to work ok if you start audio than switch to DVI...
  • [20:39:02] <suihkulokki> mmmm.. lots of traffic on linux-omap this week
  • [20:39:04] <jkridner|work> I heard koen say something about using OSS with mplayer.
  • [20:39:14] <jkridner|work> would be interesting to see if that works.
  • [20:39:21] <BThompson> it seems the alsa init does something bad to the dvi on the evm, based on what i was seeing, i was just wondering if it was the same on beagle, but it sounds like it isnt
  • [20:39:37] <BThompson> you could reproduce it with the out of box demo if you wanted to see it :)
  • [20:39:45] <jkridner|work> suihkulokki: hope that means lots of good patches.
  • [20:40:11] <BThompson> psp is already aware though, so its out of my hands
  • [20:40:18] <jkridner|work> BThompson: yikes! I don't need another TODO in my inbox!
  • [20:40:29] <jkridner|work> k. As long as PSP team is already working it.
  • [20:40:38] <BThompson> yea i wouldnt worry about it, just another piece of knowledge
  • [20:40:44] <jkridner|work> didn't come up on the Beta 2 review today.
  • [20:41:13] <BThompson> found it last week i think, had to go through a dozen different ways of making DVI and audio before Brijesh would believe me

  • [21:58:37] <mru> and the really weird thing: a pure write loop using both arm and neon stores to separate memory regions, and prefetching the addresses used for arm stores, gives the fastest write I can come up with
  • [22:04:39] <richardw> mru, have you tried PLE. Also there are some tweaks where you can make sure neon data fetches don't knock out ARM caches. I don't recall what the defaults are.
  • [22:05:15] <mru> PLE?
  • [22:05:34] <richardw> The L2 cache supports block prefetch for streaming.
  • [22:06:00] <mru> right, the preload engine
  • [22:12:04] <richardw> trivia for armv7 is it also defines a PLI but A8 profile doesn't implement it

  • [22:28:23] <jkridner|work> keyboard for strafing, mouse for aiming.

  • [22:29:11] <jkridner|work> would be nice if I could find those again.
  • [22:29:21] <gregoiregentil> jason: you are teasing us! But the main question: when will we have this dam PowerVR driver? ;-)
