  • [00:29:00] <hramrach_> I think I downloaded a copy of this from another site already. It is very brief document with no detailed information on the chip hardware features. The fact they are handled by Linux is not what I am looking to find out.
  • [00:30:55] <hramrach_> I am not even sure the DM3730 used in xM board is in any way similar to the TI chip used in C4. It uses the same ARM Cortex A8 core but it's a licensable core that can be bundled with varying other features

  • [00:32:14] <mru> just updated silicon revs and higher clock rates
  • [00:32:32] <hramrach_> which brings me back to the omap iommu
  • [00:33:25] <mru> you can get very detailed chip manuals from the TI website
  • [00:33:27] <hramrach_> I do not find it in the high level block diagrams of the chip and the only place where I found any reference to it is Linux sources which is not exactly a good source of documentation.

  • [05:36:45] <noob> how do i go about it?

  • [05:38:42] <thurbad> you have two options then, you can change the u-boot environment variables , or use boot.scr
  • [05:39:17] <noob> do you have a link for me?
  • [05:39:40] <thurbad> do you have a serial cable to get at the u-boot terminal?
  • [05:39:54] <noob> yes, i do have it
  • [05:40:34] <noob> i have it connected through putty
  • [05:41:15] <thurbad> when it's counting down before booting hit any key at the putty terminal and it should drop you into the u-boot shell
  • [05:42:32] <noob> did that. btw when i go into the u-boot shell
  • [05:42:54] <noob> i am able to see black and white bars on the screen; not there otherwise
  • [05:42:59] <thurbad> can you post the results of printenv from there to pastebin.com?
  • [05:45:14] <noob> http://pastebin.com/Luc9FUfC
  • [05:46:13] <thurbad> yeah that's what I thought, you'll need to alter the mmcargs line itself :/

  • [05:56:26] <thurbad> that should clean up your bootargs a bit, if you want to change back to dvi in the future you won't need to change mmcargs again, onlly the omapfbmode and defaultdisplay
  • [05:57:13] <noob> alright, let me try that and will get back to you
  • [06:01:32] <noob> display is on, but colour is not proper, i'll have to check if it is ntsc formatted

  • [21:23:06] <b7500af1> Anyone know what sort of speeds a person should expect from transferring data between the ARM and DSP using cached CMEM buffers? I'm getting in the range of 2-8MBps depending on the size of the buffers.
  • [21:23:30] * floholl (~flo@cpc1-belf2-0-0-cust331.2-1.cable.virginmedia.com) has left #beagle
  • [21:23:58] <_av500_> the speed is infinite
  • [21:24:07] <_av500_> since both arm and dsp can read the same cmem buffer
  • [21:25:49] <kblin> niklasfi: probably, not exactly sure what demo images you're talking about
  • [21:27:57] <b7500af1> _av500_, i guess that makes sense. Maybe i wasn't thinking that one through enough.. I was copying an input from the ARM to an output buffer on the DSP.. probably falls in that faster_memcopy category.
  • [21:28:25] <_av500_> b7500af1: for cached buffers, cache flush takes some time of course
  • [21:28:56] <_av500_> and the memcpy into the cmem buffer aslso takes time
  • [21:29:18] <b7500af1> _av500_, in a time sensitive dsp prog is it better to not use cached buffers, if you can avoid it?
  • [21:30:18] <mru> _av500_: if the cmem buffers are cached, there is no reason to memcpy
  • [21:30:27] <mru> just have whatever produces data do it directly in the cmem buffer
  • [21:30:45] <niklasfi> kblin: http://elinux.org/BeagleBoardUbuntu#Demo_Image
  • [21:32:32] <b7500af1> mru, rgr.. at the moment I was just having the DSP memcopy the data from an input to an output buffer.. eventually the memcopy would be replaced by whatever work it is to do. I was trying to get an idea for the maximum roundtrip throughput.
  • [21:33:48] <kblin> niklasfi: I'd say try it
  • [21:34:50] <koen> b7500af1: have you looked at what c6accel does for your usecase?
  • [21:35:15] <b7500af1> koen, yeah
  • [21:35:33] <_av500_> b7500af1: memcpy is not a good measure on the dsp
  • [21:35:39] <_av500_> 1) your dsp work will take more time
  • [21:35:43] <_av500_> 2) there is DMA
  • [21:36:09] <_av500_> interleave 1) and 2) and you see no memcpy effect
  • [21:36:20] <mru> interleaving is for wimps
  • [21:36:23] <mru> real men pipeline

  • [22:30:18] <mru> you have to also set a mode which includes an alpha component
