  • [10:11:59] <koen> gregoiregentil: shoot
  • [10:12:17] <gregoiregentil> koen: on my board, mplayer with fbdev is twice slower than omapfbplay. is it something you experience too?
  • [10:14:11] <gregoiregentil> I compiled omapfbplay without the NEON flag and it's the same speed. So I guess that the assembler conversion between YUV420 and YUV422 is really the trick. And mplayer is much slower because it doesn't have this assembler conversion. Am I correct?
  • [10:17:58] <koen> gr that sounds about right
  • [10:17:59] <gregoiregentil> Also, on the Angstrom webpage (http://www.angstrom-distribution.org/beagleboard-demo-image-available), it's mentioned that there is a NEON accelerated mplayer but I don't see any patch in OE for mplayer. Am I missing something?
  • [10:18:35] <koen> that mplayer is a bit ugly, it's mrus dsputil stuff manually worked into mplayer
  • [10:18:39] <koen> no patch for that, sorry
  • [10:19:39] <gregoiregentil> There is a thread between you and Jason about some benchmarking between beagleboard and n810. YOu mentioned that you were disappointed by performance (because of lack of software optimization)
  • [10:19:46] <gregoiregentil> can you clarify the status?
  • [10:28:31] <koen> one part of it was solved by enabling L2 cache
  • [10:28:47] <koen> another part was solved by disabling alignment checking (2x speedup)
  • [10:29:28] <koen> but we can't escape the fact that the vfp in the cortex is twice as slow as the one in the omap2
  • [10:31:07] <gregoiregentil> so could you list the software improvments that we could develop to improve playback?
  • [10:32:00] * shiv (n=root@59.160.172.220) has joined #beagle
  • [10:33:36] <koen> 1) add NEON versions of colourspace conversions to ffmpeg itself
  • [10:33:52] <koen> 2) add NEON versions of colourspace conversions to mplayer
  • [10:34:24] <koen> 3) teach mplayer to use the omapfb overlay (combined with 2))
  • [10:39:07] <gregoiregentil> OK. Many thanks for the list
  • [10:51:30] <pbrook> koen: Is it actually using double precision? Single precision VFP in runfast mode should use the neon unit and be comparable to the arm11.
  • [10:53:38] <koen> I have no idea which instructions the testapp was using
  • [10:53:50] <koen> it might be that it was compiled without -mfpu=neon
  • [10:54:02] <pbrook> That doesn't matter.
  • [10:55:42] <pbrook> By default you'll get iee conformant behavior, which uses teh neon unit. It you tweak the FPU in the right way (turn on flush-to-zero, disable exceptions and use the right rounding mode) it'll automatically send single precision VFP instructions through the NEON pipeline.
  • [10:56:17] <koen> don't know if that was the case here
  • [10:56:19] <pbrook> I admit I've never actually tried this on hardware, but the docs say it should work :-)

  • [16:51:26] <dirk2> but this doesn't work :(
  • [16:52:14] <sakoman> hmm . . . perhaps arm_cortexa8/omap3 ?
  • [16:52:42] <sakoman> would have to study the makefiles to be sure though
  • [16:53:33] <dirk2> hmm ... no other entry has "/". E.g. cpu/arm926ejs/davinci/ has

  • [16:56:07] <dirk2> sakoman: k. Have to think about it. Will drop you mail about success/failure
  • [16:56:24] <sakoman> it probably will require reading some of the makefiles for similar setups :-(

  • [17:11:11] <nabax> i wanted to use my beagleboard as a "media center" so audio would be kinda useful :p
  • [17:13:03] <koen> since it's a kernel problem the answer is "no, there is no distro that works better"

  • [20:50:02] <koen> yes, that was what I was getting at

The 26.Mhz and 32Khz clocks is working as and input and output. The OMAPs SYS_NRESPWRON is at a constant 1.8vdc however, the SYS_nRESWARM has a 280us pulse every 7ms.

This is the case with two beagle boards I have and I dont think its hardware, any ideas?
  • [21:32:48] <prpplague> Crofton|work: i had planned to make the daughter board the exact same size as the beagle
  • [21:33:01] <prpplague> Crofton: think it should be bigger?
  • [21:33:19] <mru> same size would make them nicely stackable
  • [21:33:49] <prpplague> mru: which was my thought

  • [22:56:10] <nathan_> Are there known problems with usbserial driver with OTG HOST on Rev B4? I have a USB/Serial device connected to a powered hub, works fine in both directions, until I activate my USB Bluetooth, Pegasus ethernet, or zd1211 wireless. At that point usbserial stops receiving bytes. I tried another powered hub with the same results. My PSU is a 5.00V benchtop supply.
  • [22:56:47] <mru> prpplague: I have a rev C prototype, and there are some minor differences in component layout from rev B (no number)
  • [22:56:52] <mru> I don't have a B4 or B5
  • [22:57:11] <nathan_> I saw the same behavior with latest Angstrom kernel and with latest linux-omap 2.6.27 running Mans' patch.
  • [22:57:37] <mru> there are no differences that should affect mounting
  • [22:58:48] * Olipro_ is now known as Olipro
  • [22:59:32] <pbrook> nathan_: There seem to be issues with OTG host mode. My usb-ethernet and keyboard work fine, but bluetooth dongles don't work, and sometimes kill the kernel.
  • [23:00:43] <pbrook> ... of course it could be the bluetoth stack that's busted, musb driver is my primary suspect though.
  • [23:00:46] <prpplague> mru yea thats mainly what i was worried about was the expansion header and the signals present
  • [23:00:47] <nathan_> Interesting. I've also had bad luck with UVC cameras. I attempted to post a stack trace to the "Camera for beagle" thread on the group, but I assume the list is moderated because I haven't seen it yet.
  • [23:01:23] <nathan_> In the case of my camera, I built the same UVC source into my desktop kernel and the cameras work fine.
