  • [10:08:48] * Crofton grumbles about the cat knocking something over and waking him up
  • [10:26:42] <koen> heh
  • [10:28:17] <Crofton> I think it was a metal salt shaker onto a granite counter
  • [10:28:28] <Crofton> sounded sort of like I would be cleaning up glass though
  • [10:35:25] <koen> Crofton: I added a helper var to select omap/davinci for dsplink
  • [10:35:38] <koen> Crofton: if I did it right, it should now build for your osk
  • [10:37:44] <Crofton> ok
  • [10:37:55] * Crofton adds that to the list of things to do
  • [10:39:01] <Crofton> the amardillo machine stuff comes from a guy who also has a sffsdr board
  • [10:39:12] <koen> amardillo?
  • [10:39:17] <koen> did I miss something?
  • [10:39:27] <Crofton> he posted it on the bugtracker
  • [10:39:35] <Crofton> http://bugs.openembedded.net/attachment.cgi?id=9715
  • [10:39:55] <Crofton> I think it is an arm1136 from freescale
  • [10:40:06] <Crofton> but that is likely a dirty word on this channel :)
  • [10:40:35] <koen> he should use linux.inc in his kernel :)
  • [10:41:34] * koen wonders where to get cmemk.ko from
  • [10:42:18] <koen> " Please note that you will hear a beeping sound after every couple of seconds
  • [10:42:18] <koen> as this is evaluation audio codec and there will be TI logo displayed on
  • [10:42:19] <koen> right hand corner as this is evaluation video codec."
  • [10:42:23] <koen> cute :)
  • [10:42:30] <koen> (http://focus.ti.com/en/download/dsp/gstreamer_license_readme.txt)
  • [10:43:53] <kulve> where did you get link to that?
  • [10:44:02] <koen> google :)
  • [10:44:19] <koen> http://wiki.davincidsp.com/index.php?title=GStreamer might be a bit more informative, though
  • [10:47:24] <kulve> thanks
  • [10:48:55] <Crofton> koen, did you see this?
  • [10:49:09] <Crofton> http://bugs.openembedded.net/show_bug.cgi?id=4312
  • [10:49:41] <koen> hadn't seen that yet
  • [10:51:03] <koen> and dsplink.bb doesn't seem to be using any packaged-staging features
  • [10:52:18] <Crofton> apparently something subtle is going on
  • [10:52:57] <Crofton> Rod sounded like he had looked into it some
  • [10:53:45] <Crofton> must not be too many martians near the poles
  • [10:53:59] <Crofton> the lander made it through the martian defenses
  • [10:57:37] <koen> it could be the KERNEL_VERSION thingy
  • [10:58:18] <Crofton> what's that lcd thing you have?
  • [10:59:26] <koen> http://dominion.thruhere.net/koen/cms/lcd2usb-attached-to-a-macbookpro <- that one?
  • [10:59:54] <koen> it's a kit from http://www.harbaum.org/till/lcd2usb/index.shtml
  • [11:00:09] <koen> I have lcd4linux running on the beagle :)
  • [11:00:19] <koen> (till ehci locks up, of course)
  • [11:01:55] <Crofton> it has buttons?
  • [11:03:07] <Crofton> I need to make a dsp cave radio location RX one day
  • [11:03:31] <koen> it has buttons, yet
  • [11:03:39] <koen> haven't tried to use them
  • [11:04:13] <Crofton> http://radiolocation.tripod.com/
  • [11:04:48] <Crofton> basically, I need to feed in a 3.496 khz signal and measure the strength
  • [11:05:13] <Crofton> I have the analog set (that I need to check out today for next weekend)
  • [11:05:58] <Crofton> http://www.flickr.com/photos/32615155@N00/99900423/in/set-72057594064619360/
  • [11:06:37] <Crofton> The beagle is overkill for the signal processing
  • [11:07:07] <koen> there's no such thing as overkill
  • [11:07:27] <Crofton> spoken like a true academic :)
  • [11:07:54] <Crofton> The guy that designed the analog version will point out the analog versino is cheaper and needs less power

  • [12:40:06] <ldesnogu> hello
  • [12:41:54] <ldesnogu> given how stupid I was, I changed my pass :P
  • [12:44:06] <koen> :)
  • [12:59:16] <koen> Crofton: for davinci we also seem to need codec engine 2.10 to get cmem.ko
  • [12:59:40] <Crofton> yeah
  • [12:59:49] <Crofton> I am not sure how to get that
  • [13:00:02] <Crofton> does dsplink depend on cmem.ko?
  • [13:00:56] * koen dunnos
  • [13:01:25] <Crofton> It is a holiday here today, so it may be tomorrow before someone that knows the answer appears
  • [13:15:12] <koen> ah
  • [13:15:29] <koen> the 50+ MB codec engine download also has dsplink
  • [13:32:54] <Crofton> yeah
  • [13:33:00] <Crofton> can we dl codec engine?
  • [13:37:27] <ldesnogu> Crofton, http://focus.ti.com/dsp/docs/dspsupporto.tsp?sectionId=3&tabId=1460#invent
  • [13:37:41] <ldesnogu> but it looks like it's only for DM...
  • [13:37:53] <ldesnogu> and not free
  • [13:39:25] * ldesnogu suddenly wonders if Crofton was talking about codecs or code engine framework
  • [13:40:19] <Crofton> not sure :)
  • [13:41:01] <ldesnogu> :)
  • [13:44:32] <Crofton> we are puzllling through all this stuff
  • [14:03:17] <koen> # Look for tarball at https://www-a.ti.com/downloads/sds_support/targetcontent/CE/index.html
  • [14:21:34] <bazbell> cmem is the contiguous memory allocator module that codec engine does depend on. http://wiki.davincidsp.com/index.php?title=Changing_the_DVEVM_memory_map and http://wiki.davincidsp.com/index.php?title=Codec_Engine_Roadmap
  • [14:23:09] <Crofton> ok
  • [14:23:21] <Crofton> but dsplink does not depend on cmem
  • [14:23:33] <Crofton> I'm also guessing codec engine is not open source?
  • [14:23:46] <bazbell> Codec Engine 2.10 includes CMEM 2.10 and DSP/BIOS Link 1.50.
  • [14:23:55] <bazbell> Codec engine is not open source at this time.
  • [14:24:13] <Crofton> in a nut shell, what does codec engine do for us?
  • [14:29:15] <bazbell> Codec Engine is a set of APIs that instantiate and run xDAIS algorithms. The algorithm may be run on the GPP or remotely on the DSP. It supports GPP+DSP, DSP-only or GPP-only devices with the same APIs. I don't know if that quite answers your question.
  • [14:31:08] <Crofton> I'm trying to figure out how it would fit in open source efforts ....
  • [14:32:27] <suihkulokki> I wouldn't hold my breath :| codecs are patent disaster.
  • [14:33:12] <Crofton> but the engine could be useful to signal processing stuff
  • [14:33:32] <Crofton> as a first pass, just being able to run code on the dsp is goof
  • [14:33:36] <Crofton> er good
  • [14:33:56] <suihkulokki> yes that would be nice
  • [14:37:00] <bazbell> As Crofton mentioned, codec engine is the framework that runs codecs, not the codecs themselves. Personally, I would have preferred a more generic name like "algorithm engine", but I digress...
  • [14:37:14] <Crofton> heh
  • [14:37:22] <Crofton> what license is it under?
  • [14:39:56] <bazbell> I need to check, but I believe it is provided with the DVSDK package which does have a license. As we discussed, not open source.
  • [14:46:44] <Crofton> all this license stuff gets confusing :)
  • [14:47:18] <Crofton> I need to do a talk on the beagle and SDR in 10 days.
  • [14:47:49] <Crofton> I need to get a good feel for the cortex-a8 signal processing capability and available software
  • [14:58:45] <bazbell> Actually, Codec Engine is part of the Multimedia Framework Products which is available via the Code Composer Studio Update Advisor path. Therefore, it would be under the CCS license. DSP/BIOS Link would also fall under that category. Sorry, I realize this is confusing and it took me a bit to sort out that specific question.
  • [15:17:42] <koen> it helps that I've seen Rishis presentations on omap and davinci :)
