  71. [04:26:26] <thurbad> is there any driver out there for the audio chip on the beagle, or perhaps a power management setting that will prevent the pop after audio stops playing with angstrom/beagle?
  72. [04:27:28] <thurbad> or do I need to continuously stream some sort of sound to prevent the pop?

  89. [05:29:08] <hitlin37> how to i change my resolution,its only giving 640*480
  90. [05:30:02] * hvaibhav (~a0393758@192.163.20.231) has joined #beagle
  91. [05:30:13] <ds2> YOU can read the source, learn it and report back.
  92. [05:33:09] <thurbad> hitlin37, you need to modify the arguments sent to the kernel
  93. [05:34:14] <hitlin37> which file i need change
  94. [05:35:24] <thurbad> you need to modify the u-boot environment variables... you can do this either in the u-boot terminal with a serial connection or create a boot.scr file and place it in the SD boot sector
  95. [05:36:13] <thurbad> I'll pastebin a copy of the file I use to generate boot.scr if you want

  105. [05:45:42] <thurbad> you can use 'printenv' to see the variables already stored
  106. [05:47:07] <hitlin37> ok
  107. [05:50:51] * jpirko (~jirka@ip-89-103-91-100.net.upc.cz) has joined #beagle
  108. [05:55:13] <hitlin37> printenv gives me lot of vaiables
  109. [05:55:21] <hitlin37> DISPLAY:0.0
  110. [05:55:27] <av500> thurbad: should be fixable in the driver
  111. [05:56:14] <thurbad> hitlin37, is there a dvimode variable?
  112. [05:56:40] <thurbad> I can't remember if that's a default variable or one I added
  113. [05:57:03] <hitlin37> no
  114. [05:57:07] <hitlin37> no dvimode
  115. [05:57:34] <thurbad> ok, it's probably something I added then
  116. [05:57:42] <hitlin37> i built image using narcissus,did i missed anything important
  117. [05:58:05] <thurbad> no
  118. [05:58:19] <thurbad> these are variables that live in the nand
  119. [05:58:42] <hitlin37> ok
  120. [05:59:08] <hitlin37> then should i create boot.scr now
  121. [05:59:22] <thurbad> that would be the easy route
  122. [05:59:35] * tommost_ (~tommost__@71-211-233-58.hlrn.qwest.net) Quit (Remote host closed the connection)
  123. [05:59:52] <hitlin37> but theres already MLO ,u-boot and uImage
  124. [05:59:53] * amitk (~amit@a91-154-124-12.elisa-laajakaista.fi) has joined #beagle
  125. [05:59:54] <hitlin37> in boot
  126. [06:00:27] <hitlin37> so again i'll put boot.sscr there,in which order
  127. [06:00:28] <thurbad> yup, boot.scr is optional it's just a script that lets you interact a little with u-boot
  128. [06:00:45] <av500> thurbad: you could try to mute the audio before it stops playing
  129. [06:00:53] <thurbad> boot.scr shoulld be added last
  130. [06:01:01] <hitlin37> ok
  131. [06:01:02] * screwgoth (~raseel@122.169.75.195) has joined #beagle
  132. [06:01:09] <av500> it really depends on the audio chip itself, and I know little about what the TWL does..
  133. [06:01:22] <thurbad> av500, ok I'll try that before trying to modify the driver
  134. [06:01:42] * Belna (~Thomas@DSL01.212.114.252.242.ip-pool.NEFkom.net) has joined #beagle
  135. [06:01:54] <av500> thurbad: its a common issue, at least here :)
  136. [06:02:05] <av500> been fighting it for years on various codecs
  137. [06:02:06] <hitlin37> how do i create boot.scr
  138. [06:02:14] <av500> its in the wiki
  139. [06:02:18] <hitlin37> :)
  140. [06:02:54] <thurbad> these are the settings that I use ... http://pastebin.com/24Q1jhEa
  141. [06:03:22] <thurbad> I have dvimode separated out for easy modification
  142. [06:04:30] <hitlin37> ok ,let me try it
  143. [06:05:09] <thurbad> I also keep the command line at the top commented out that is used to generate the boot.scr from a simple text file named bootargs.txt
  144. [06:05:27] * rcranetx (~rcranetx@nat/ti/x-sdwqbugurqakgazs) Quit (Remote host closed the connection)
  145. [06:05:50] <thurbad> you'll probably have to apt-get installl mkimage if you don't have it already installed on your system
  146. [06:06:30] * rcranetx (~rcranetx@nat/ti/x-zicrfawrazyhzvpm) has joined #beagle
  147. [06:06:56] <thurbad> you can leave off the saveenv line if you don't want to permanently alter your boot environment
  148. [06:08:15] <thurbad> and the optargs I'm using hides the boot messages and splash screen when booting... may not be what you want, but it speeds up the boot process
  149. [06:10:17] <hitlin37> u mentioned mmcargs.txt in first line
  150. [06:11:28] <thurbad> ah, yeah, that's the name of my text file, not bootargs.txt
  151. [06:11:41] <thurbad> sorry for any confusion there

  162. [06:25:07] <thurbad> if you want to change the resolution all you have to do is modify the dvimode variable
  163. [06:25:23] <hitlin37> ok

  165. [06:26:01] <thurbad> for instance mine is set to 1280x720 and 24 bit color depth
  166. [06:26:40] <thurbad> rather than the default 16 bit color depth which is quite ugly
  167. [06:26:55] <hitlin37> ya i can see that,thanks

  172. [06:33:52] <ds2> do it in software
  173. [06:34:09] <ds2> multiple the audio with a decaying signal before you end it
  174. [06:34:29] <av500> ds2: might not help
  175. [06:34:48] <av500> it really depends on what the codec does when you stop feeding it data
  176. [06:34:58] * Crofton (~balister@pool-96-240-180-89.ronkva.east.verizon.net) Quit (Ping timeout: 265 seconds)
  177. [06:35:19] <thurbad> the sample ends a second or 2 before the pop from the driver shutting off power to the speakers.. or at least that 's what seems to be the cause
  178. [06:36:08] <av500> ok, so its more the shutdown of the codec
  179. [06:36:12] <av500> then just keep it alive
  180. [06:36:17] <hitlin37> i need libavutild-dev package (i downloaded it),but it has further dependecy to other libs,i should i go now,first to install all those libs then libavutil-dev or how?
  181. [06:36:44] <hitlin37> i*how
  182. [06:36:56] <thurbad> hitlin37, on the beagle or on a dev machine?
  183. [06:37:13] <thurbad> opkg should resolve dependencies
  184. [06:37:14] <hitlin37> beagle, i already hav it on my dev machine

  191. [06:48:13] <thurbad> ugh got to test a user space 'driver' for hardware I have a prototype for that is slightly different than the actual hardware using the spec the actual hardware
  192. [06:48:23] <thurbad> ... not looking forward to this
  193. [06:48:42] <av500> ?
  194. [06:48:53] <thurbad> dunno if I'm even gonna get past initialization
  195. [06:50:19] <thurbad> sensor stuff, the prototype only measures 2 axes the actual hardware measures 3
  196. [06:51:06] <av500> i2c?
  197. [06:51:10] <thurbad> not sure why since we're technically only measuring 1 axis
  198. [06:51:12] <thurbad> yeah
  199. [06:51:32] <av500> i2c is simple
  200. [06:52:15] <thurbad> I'm more concerned with the protocol of the sensor initialization at this point :/

  205. [07:00:28] <thurbad> av500, when you (you specifically not generally) do i2c, do you usually write a kernel module, or user mode code?
  206. [07:01:22] <av500> we do it in kernel
  207. [07:04:53] <thurbad> I probably should have done it that way, but the only kernel stuff I've ever mucked with was in Minix
  208. [07:05:32] <thurbad> not exactly a practical real world kernel experience

  212. [07:06:59] <av500> what chip?
  213. [07:07:47] <thurbad> LIS302DL
  214. [07:08:52] <thurbad> at least that's the final hardware, the prototype is a similar 2-axis version that I don't have a chip number for

  216. [07:09:57] <thurbad> there's a little more too, it though.. there's multiple sensors with a multiplexor to address the various sensors
  217. [07:10:00] <av500> this driver is even blessed
  218. [07:12:25] <thurbad> looks like that driver uses spi rather than i2c, thanks though
  219. [07:12:39] <av500> yeah, but register map is the same i guess

  223. [07:15:59] <av500> well, that is the same for user space...
  224. [07:16:17] <thurbad> I was told that it's virtually identical, but don't have a lot of faith in the source of that info at the moment

  277. [08:38:01] <neo01124> jacekowski, the module is userland only
  278. [08:38:30] <jacekowski> you just said kernel
  279. [08:38:36] <thurbad> is it a kernel mod or user space? you said kernel first
  280. [08:39:45] <thurbad> if it's user space you just include the appropriate headers and call the API functions directly as needed
  281. [08:40:15] <thurbad> and link the library when you build it
  282. [08:41:28] <neo01124> this is the one http://github.com/neo01124/omap3-pwm/blob/master/pwm.c
  283. [08:41:59] <jacekowski> that's kernel module
  284. [08:42:26] <jacekowski> you have to build it
  285. [08:42:27] <jacekowski> and load it
  286. [08:43:49] <neo01124> that is what i was asking , how to load it from C ?
  287. [08:43:59] <jacekowski> compile it

  289. [08:45:35] <neo01124> thurbad, yes
  290. [08:45:52] <jacekowski> load that module
  291. [08:46:28] <neo01124> jacekowski, i know how to load it. one way of using it is this http://github.com/neo01124/omap3-pwm/blob/master/examples/file_operations.c
  292. [08:46:40] <jacekowski> and then use it's file in /dev/
  293. [08:46:54] <jacekowski> there is full set of ioctls
  294. [08:47:37] <thurbad> so it exposes the access through the filesystem?

  454. [11:26:41] <thurbad> when doing gpio via sysfs... do you need to close and reopen the gpio file after you write something to it?
  455. [11:27:03] <_koen_> iirc emeb said he didn't
  456. [11:27:08] <_koen_> it "rewinds" automagically
  457. [11:29:04] <thurbad> odd, it's erroring for some reason... I have interrupt lines, I can clear it once, then it fails... but the address lines aren't failing to be rewritten going to the muxer

  464. [11:46:16] <thurbad> ok, apparently it handles the file position after a write, but not after a read... does that sound inconsistent to anyone else?
  465. [11:47:27] <_koen_> yes
  466. [11:48:27] <thurbad> does angstrom even handle suspend/wake?
  467. [11:50:23] <_koen_> what do you mean?
  468. [11:50:37] <_koen_> the kernel should handle suspend wake
  469. [11:50:47] <_koen_> but on omap3 runtime pm is more usefull
  470. [11:50:56] <_koen_> that can hit OFF mode without suspending
  471. [11:51:10] <_koen_> provided the apps you are running aren't polling every ms
  472. [11:51:45] <_av500_> and no suspend blocker!

  482. [11:56:12] <thurbad> what's in the other includes that it includes?
  483. [11:57:19] <thurbad> if you're going to do much gpio you'll probably want a modified u-boot that enables the stuff you need then you can export them as needed
  484. [11:57:42] <thurbad> by default a lot of the potential gpio pins are used for other stuff

  675. [14:04:00] <Kmus> hmm... stack corruption?
  676. [14:04:08] <screwgoth> Kmus: Nope ... no segfault .... which is why I spent a lot of time debugging at the wrong places

  680. [14:04:59] <Kmus> the MMU should trap any illegal writes to memory you don't own, so unless your trashing your own data and somehow exitting?
  681. [14:05:43] <screwgoth> Kmus: Hmm... I thought memmove() was how you prevented memory overlaps ....
  682. [14:05:59] <Kmus> no idea, I don't use that.. I memcpy everywhere required :)
  683. [14:06:32] <Kmus> hmm.. looked at memmove, doesn't seem to offer any safety
  684. [14:06:51] <screwgoth> Kmus: Also, linphone uses memcpy() quite a number of times
  685. [14:06:55] <Kmus> just allows src/dst memory to overlap
  686. [14:07:08] <Kmus> its not the memcpy, its where your copying too (i.e. destination)
  687. [14:07:30] <screwgoth> I had g_malloc0() a gpointer
  688. [14:07:46] <Kmus> hmm.. that makes no sense to me :) must be application specific (g_malloc)
  689. [14:07:53] <DaveDavenport> g_malloc is glib
  690. [14:07:56] <screwgoth> as in, the g_malloc0()'d gpointer was the destination
  691. [14:07:57] <DaveDavenport> works like normal malloc
  692. [14:08:06] <DaveDavenport> *in usage
  693. [14:08:08] <screwgoth> DaveDavenport: yup ... glib's g_malloc0
  694. [14:08:09] <Kmus> ah ok
  695. [14:08:34] <screwgoth> pretty much ... I guess it's like malloc()ing and then memset()ing ..
  696. [14:08:37] <Kmus> screwgoth - so the destination memory is freely malloc()ed then memcpy is used? and the line after the memcpy is never reached?
  697. [14:08:49] <screwgoth> Kmus: correct
  698. [14:08:58] <Kmus> what is the data in question?

  703. [14:09:37] <screwgoth> It's video data
  704. [14:10:21] <Kmus> well, for testing.. you could not memcpy and see what happens..
  705. [14:10:39] <Kmus> incase its something else that's just masked by memcpy

  709. [14:12:27] <Kmus> but having no error, thats weird.. how are you testing this, full GDB debugging (stepping through code)?
  710. [14:12:31] <screwgoth> Also, is it because the video frame in question is 153600 bytes .. about 15K
  711. [14:13:13] <Designer> Hi
  712. [14:13:35] <Designer> Will Windows CE5.0 work with the Beagle Board ?
  713. [14:13:35] <Kmus> Afternoon
  714. [14:13:35] <screwgoth> Well.. that's another issue :-) .. I setup remote debugging ... but the app just gets stuck after the error ... but that's pro'ly because I didn't setup gdbserver/gdb correctly
  715. [14:14:22] <Kmus> That makes it hard to get it right, too many false trails to follow

  721. [14:16:36] <Kmus> What would u use koen?
  722. [14:16:37] <screwgoth> Kmus: Lemme try your earlier suggestion .. also I'll just cut the frame to see if it's a size issue

  724. [14:16:47] <Kmus> depends, some people have pipelines to do effects on data
  725. [14:17:05] <Kmus> screwgoth : malloc may be failing too :)
  726. [14:17:18] <screwgoth> _koen_: Like Kmus mentioned DMA .. or to pass the videoframe to the DSP ..
  727. [14:17:32] <screwgoth> Kmus: I check that ... it's not.
  728. [14:17:36] <_koen_> point the dsp mmu to the first buffer
  729. [14:17:40] <Kmus> I`m actually developing a pipeline system atm, its smart enough to not copy data unless there's changes.. so its pointer passing
  730. [14:17:42] <_koen_> no need to copy things around
  731. [14:18:11] <Kmus> True, unless you need to ;)
  732. [14:18:41] <screwgoth> _koen_: Makes sense .. I'll try to avoid the memcpy() altogether
  733. [14:18:49] <Designer> Has anyone load the Beagle Board with Windows CE 5.0 image ?
  734. [14:18:54] <Kmus> Anyone else use Eclipse? I`ve never met a program that leaks memory SO badly, and people don't do anything about it..
  735. [14:19:12] <Kmus> Designer - not that I`ve heard off, but I beleive its possible
  736. [14:19:17] <mru> Kmus: it's java, it's meant to be like that
  737. [14:19:27] <DaveDavenport> I don't know why people use it
  738. [14:19:30] <DaveDavenport> its terrible
  739. [14:19:37] <mru> it's enterprisey
  740. [14:19:44] <Kmus> mru - but even with the manual garbage collection is leaks badly.. over a few hours of development and debug, there about 300mb wasted O_o
  741. [14:19:57] <Kmus> one of the reasons I hate Java, except for GWT stuff :P
  742. [14:19:57] <mru> yes, that's how java works
  743. [14:20:25] <Kmus> Java isn't supposed to leak memory, its supposed to release it (eventually) back to the system
  744. [14:21:11] <thurbad> you can still leak memory with poorly written code
  745. [14:21:34] <mru> Kmus: any garbage collector is designed to release memory eventually
  746. [14:21:35] <Kmus> Yea, hence my complaint that Eclipse developers dont seem to care.. they use the 'Its Java' excuse :|
  747. [14:21:44] <mru> usually eventually is very far into the future

  749. [14:21:57] <Kmus> :)
  750. [14:22:38] <mru> garbage collection only makes sense if everything sharing the same physical memory pool uses the same gc instance
  751. [14:22:58] <Kmus> Why would that not be the case?
  752. [14:23:10] <mru> because you're running other things than eclipse on the computer
  753. [14:23:19] <mru> all sharing the same physical memory
  754. [14:23:44] <mru> the eclipse gc is blissfully unaware that firefox is _also_ trying to grab as much as it can
  755. [14:23:48] <screwgoth> Ok confirmed .. it was a size issue. I memcpy()'d 1/10th the data ... and it was successful...
  756. [14:24:03] <Kmus> Ah, I talking about purely Eclipse here.. its leaking memory badly, other's (probably) are too but they don't kill a system in a few hours
  757. [14:24:14] <Kmus> screwgoth : cool :)
  758. [14:24:26] <Kmus> still should have seen some segfault :P
  759. [14:24:33] <Kmus> maybe GDB stuff is failing to remotely deliver that
  760. [14:24:37] <mru> no, it's not leaking
  761. [14:24:41] <mru> not from its point of view
  762. [14:24:54] <Kmus> it has no concept of a memory leak
  763. [14:24:55] <mru> it doesn't know the system is low on ram
  764. [14:24:59] <screwgoth> no no.. this was GDB debugging .... I had a printf() and the app just exits ...
  765. [14:25:27] <screwgoth> Oops .. I though Kmus was talking to me :-)
  766. [14:25:45] <mru> screwgoth: he was
  767. [14:26:08] <Kmus> mru : what I`m saying is that even with garbage collection (forced or otherwise) Eclipse leaks memory - the GC can never reclaim the processes memory until Eclipse is closed/opened
  768. [14:26:11] <mru> eclipse thinks it's the only think in the universe that matters
  769. [14:26:19] <mru> thing
  770. [14:26:36] <mru> therefor, sitting on some unused memory does no harm
  771. [14:26:41] <Kmus> screwgoth : so your app runs when copying less data?
  772. [14:26:51] <mru> it will recycle it when something _within_ requests it
  773. [14:27:03] <Kmus> mru : harm = slow system / lower memory for other processes
  774. [14:27:15] <mru> other processes don't exist in it's view of the universe
  775. [14:27:19] <mru> its
  776. [14:27:55] <Kmus> I understand that, but Eclipse starts off debugging apps using around 40Mb of memory.. give it a few hours and its 400Mb

  808. [14:58:38] <_av500_> the omap3 has one

  816. [15:02:12] <emeb> sakoman's driver has a fair amount of code devoted to that, but there are are some 'Revisit' comments in there.
  817. [15:02:43] <emeb> the fact that it doesn't pop at the beginning is a good sign - maybe it just needs a bit of work on the backend

  844. [15:32:52] <jkridner1> If you can explain an efficient development flow with OE, I would try it. So far, it slows me down in any project development and only helps me in integration (and maybe release).
  845. [15:34:35] <jkridner1> git is a far more productive way to manage patches, imo.
  846. [15:36:45] <jkridner1> u-boot is dying between cmd_i2c.c:1216 and omap24xx_i2c.c:445.
  847. [15:37:02] <jkridner1> (as long as argc is actually == 1)
  848. [15:38:34] <_koen_> bitbake -b foo.bb -c compile
  849. [15:38:46] <_koen_> and I use git to manage patches as well
  850. [15:38:57] <_koen_> but when I'm finished I put them into the recipe
  851. [15:38:59] <jkridner1> so, that just adds extra steps.
  852. [15:39:15] <_koen_> and?
  853. [15:39:36] <jkridner1> so, I'll do them when I'm closer to release.
  854. [15:39:36] <_koen_> do I need to remind how long it took to get the source to the magic kernel on xm?
  855. [15:40:21] <_koen_> for me it's still '<up arrow> enter'
  856. [15:40:31] <_koen_> it would be the same for 'make'

  926. [16:25:55] <_av500_> you would have:

  928. [16:26:13] <_av500_> fb is rgba32 with alpha channel

  936. [16:28:31] <_av500_> thats alpha mode vs normal mode in the TRM
  937. [16:29:07] <topfs2> Not sure how to attach sgx and such to the proposed fb but I guess I should be able to create a pixmap or something via egl
  938. [16:29:29] <_av500_> but sgx is already on the gfx/fb0
  939. [16:29:41] <_av500_> nothing to attach
  940. [16:29:47] <hitlin37> MPEG2 1280x720 (aspect 3) 59.940 fps
  941. [16:29:54] <hitlin37> ur guess was right
  942. [16:29:58] * _av500_ is a good guesser
  943. [16:29:59] <topfs2> oh? so I could keep it attached to fb0 and just switch overlay during render?
  944. [16:30:13] <topfs2> I'd assume the overlay read from the fb?
  945. [16:30:14] <hitlin37> it plays using mplayer on x86
  946. [16:30:21] <hitlin37> but
  947. [16:30:23] <_av500_> well, it better
  948. [16:30:31] <_av500_> topfs2: not from fb0
  949. [16:30:35] <_av500_> from fb1
  950. [16:31:29] <topfs2> hmm, I think I'm missing something to understand it :) Wouldn't I need to render everything over the video to fb1 then?
  951. [16:31:42] <hitlin37> i hav seen d same video played at normal speed by someone using gstremer (internally many good ,bad ugly plugins)

  1008. [17:34:44] <koen> when you say 'porting', you mean 'compiling', right?

  1020. [17:41:43] <arundp1> koen: so for compiling c++ and openCV with QT gui support, which options in narcissus should I choose. Is the default ones like unstable; regular ( basesystem ), udev, no ( software manifest ), none (SDK), user env as console . ? Please Help :)
  1021. [17:43:56] <woglinde> you only need to compile your own software
  1022. [17:44:14] <woglinde> for this you need a sdk with compiler and qtlibs and opencv libs

  1068. [18:32:43] <surplus> Hi, can anyone post a link that shows how the boot process works for the beagleboard? I'm thinking about getting one to mess around with and am doing some research
  1069. [18:33:12] <woglinde> surplus what intrested in detail?
  1070. [18:33:38] <surplus> woglinde: A general overview would be nice
  1071. [18:34:03] <woglinde> hw -> xloader/mlo -> u-boot -> kernel
  1072. [18:34:32] <woglinde> xloader can be loaded via sd-card, serialconsole, highspeed-usb or nand
  1073. [18:34:40] <Jefro> surplus I just covered the basic process in a talk at OSCON, but haven't published anything yet that describes all the bootloader process details. however, you can see everything you'd want to know by searching on "ARM boot process" or "OMAP boot process".
  1074. [18:35:07] <surplus> Okay, thanks a lot

  1076. [18:36:01] <Jefro> beagleboard is just like any other OMAP-based SBC in this regard. The hardware ROM invokes MLO using a standard search mechanism. The only beagleboard feature I can think of is the user button, which changes the order when pressed while powering on - in that case it looks on the SD card first instead of in NAND first.
  1077. [18:36:31] <Jefro> For MLO and beyond, there is some information in the BeagleBoard system reference manual, a link for which is on http://beagleboard.org
  1078. [18:36:33] <Jefro> hope that helps!
  1079. [18:36:59] <koen> you can cheat and prepend a config header to the zImage

  1220. [23:10:21] <_av500_> jacekowski: lol about fuse wiping
  1221. [23:10:46] <emeb> fuses are volatile? who knew?
  1222. [23:11:21] <_av500_> even if they were, resetting them to 0 does not help
  1223. [23:11:34] <djlewis_> gn all

  1228. [23:13:15] <emeb> unless they're in flash, which I doubt.

  1230. [23:14:09] <emeb> my guesses are: 1) fusible links blown by high current
  1231. [23:14:20] <emeb> 2) bond-out wires to inaccessible pads on die
  1232. [23:14:34] <emeb> 3) frickin' lasers

  1236. [23:16:46] <_av500_> no xray will reset those
  1237. [23:16:50] <emeb> yep
  1238. [23:17:06] * emeb has designed chips w/ option 2)
  1239. [23:17:19] <_av500_> and if the fuse array is crc protected, even resetting does not help
  1240. [23:17:34] <_av500_> it will just brick it more
  1241. [23:17:44] <_av500_> hs is hs for a reason

  1251. [23:25:12] <emeb> cool - that's what I thought reading the TRM.
  1252. [23:25:31] <emeb> looked like the controllers were separate
  1253. [23:25:43] <_av500_> yes
  1254. [23:25:54] <_av500_> tv venc and parallel output work in parallel
  1255. [23:26:09] <emeb> wonder what you'd have to do with the linux driver to make that happen...
  1256. [23:26:13] <_av500_> not much
  1257. [23:26:21] <_av500_> some sysfs tweaking
  1258. [23:26:31] <_av500_> and some content on one of the video overlays
  1259. [23:26:57] <emeb> ah - just parameters to the existing driver & write some stuff to memory...
  1260. [23:27:02] <_av500_> e.g. gfx->hdmi
  1261. [23:27:07] <_av500_> and vid1/2 -> tv
  1262. [23:27:24] <_av500_> read the dss docs in linux/doc/arm/omap
  1263. [23:27:35] <emeb> cool - I'll do that.

  1268. [23:28:52] <emeb> not much else use for it since NTSC is mostly gone here in the US now...
  1269. [23:30:10] <_av500_> add some vram for fb1 to the cmdline
  1270. [23:30:37] <_av500_> then open /dev/fb1 and put your yuv image inside
  1271. [23:30:48] <_av500_> and some sysfs tweaks
