  • [02:12:53] <bgat> Hi guys. :-)
  • [02:13:32] <bgat> Anyone aware of any lingering issues with BBB and similar boards, which hang during high SD card throughput?
  • [02:14:05] * honestly raises a brow
  • [02:14:28] <honestly> hitting the sd card will make your system stall like all fuck
  • [02:14:38] <bgat> I've got a few OMAP boards that are basically BeagleBoard clones, running several different 3.x kernels, and I get a very sporadic hang that appears to be SD card related.
  • [02:14:48] <bgat> Well, this doesn't seem to be a "stall", more like a deadlock.
  • [02:14:49] <honestly> define hang
  • [02:15:47] <prpplague> bgat: try bumping the max hsmmc clock down to 25mhz or less to see if the issue goes away
  • [02:16:06] <veremit> what manufacturer of SD card?
  • [02:16:08] <bgat> I don't have a kernel log in front of me, but the kernel reports that an SD-related thread has been blocked for more than X seconds. (I'm getting some of the information secondhand, going to get my own log tomorrow I hope but the problem is DARNED hard to reproduce.)

  • [02:17:00] <bgat> Several different brands of cards, I don't have a list. I just got the phone call a little while ago asking for help. :-)
  • [02:17:53] <bgat> I glanced at several different versions of omap_hsmmc.c, and I don't see a lot of use of spin_lock_irqsave(). Which I find troubling.
  • [02:17:55] <prpplague> veremit: got all the paper done then?
  • [02:18:12] <veremit> prpplague... damn papers :p
  • [02:18:23] <bgat> @prpplague: that's a good idea.

  • [02:19:41] <bgat> Basically, the board occasionally dumps a big chunk of stuff out to SD, the average throughput is low but bursty. They see the problem more frequently when they're doing DSP code at the same time, or other things that cause extra interrupts.

  • [08:33:16] <hvn> KotH: I've read that book, as well as Tanenbaum and others.....but my question was for an easy and maybe quick way to check like memtest86 does. Problem is that when I boot my BBxM, I don't have such an option
  • [08:33:50] <av500> when synaptic crashes, does it always crash in the same place?
  • [08:33:55] <av500> run it under gdb and see
  • [08:34:19] <KotH> hvn: i'm surprised that memtest_86_ isnt installed on your system
  • [08:34:22] <LetoThe2nd> hvn: there is none, because arm boards usually don'thave the bios/bootloader/memtest thing
  • [08:34:46] <LetoThe2nd> hvn: u-boot includes some minimal means of memory testing, but its far from being reliable
  • [08:35:19] <LetoThe2nd> hvn: you could try and do something with a jtag - but also that won't give you guarantees.
  • [08:36:00] <av500> debug the crash first
  • [08:36:07] <LetoThe2nd> but i agree with av500 - most likely not memory is corrupt, but your rootfs
  • [08:38:00] <hvn> av500: yes it does. As soon as you see the GUI, it crashes. I just rebooted, and "free" showed 329009k. After the synaptic crash, it shows 297840k.
  • [08:39:28] <av500> what does "free" output prove?
  • [08:39:35] <LetoThe2nd> think buffers and friends. no news there.
  • [08:39:54] <av500> its not like bad RAM disappears
  • [08:40:08] <hvn> LetoTh2nd: I suspected my flashcard first, but when I replaced it with a brand new one, the problems were still there. So I suspected RAM
  • [08:40:38] <hvn> av500: I agree. This basically rules out bad RAM
  • [08:40:57] <LetoThe2nd> hvn: "brand new" means nothing when it comes to sd cards, especially consumer class. and if you just put the same data onto it, nothing will change.
  • [08:41:59] <av500> its not a bad card either
  • [08:42:12] <av500> maybe it just crashes due to a .... bug
  • [08:42:24] <hvn> LetoThe2nd: I know, but the image I've restored to the card is an image I've used for quite some time without any problems. So I don't suspect that to be the cause of the problems
  • [08:42:24] <LetoThe2nd> yes! b??g!
  • [08:42:48] <LetoThe2nd> hvn: like av500 already said - gdb it and see where it explodes.
  • [08:47:26] <hvn> av500: well, bugs are usually solved by updates and I can't do that because of the crashing...first check with gdb gives the message "not a core dump" so will check further

  • [13:00:26] <KotH> spoonox: 1% is not stable ;)
  • [13:00:58] <KotH> LetoThe2nd: i guess for you rachmaniov is also b??ring

  • [13:01:14] <philenotfound> LetoThe2nd: also deprec??ted

  • [22:17:57] <Martin__> (with its own registers)
  • [22:17:59] <KotH> oh.. yes.. you are probably using a pre-DT kernel
  • [22:18:10] <KotH> this means you have to modify the boardfile
  • [22:18:44] <KotH> the boardfile is basically a c description of what the hardware looks like (or rather how it should be initialized)
  • [22:18:57] <KotH> you'll find it in the kernel sources
  • [22:20:35] <Martin__> Do you know about some detailed tutorial I could read?
  • [22:20:44] <KotH> sorry, i dont
  • [22:21:36] <Martin__> Ok Thanks.
  • [22:22:25] <mdp> original BeagleBoard: http://elinux.org/BeagleBoardPWM
  • [22:22:43] <mdp> recommend you look around the elinux.org/BeagleBoard pages
  • [22:24:56] <mdp> there's no upstream pwm driver for the omap timers so you'll find N different way to do this...out of tree one-off drivers living on github..etc.
  • [22:25:15] <mdp> and so it works differently than beaglebone with have standard kernel pwm drivers with a well-known api

  • [22:34:55] <mdp> the proper approach is to use the omap timers as designed
