  • [01:33:19] <xterm91> uEnv.txt is Legacy to the original BB?

  • [01:37:45] <levi> Why do you want to put ubuntu on the eMMC?

  • [01:43:21] <xterm91> Is anyone else curious about possibly getting Netflix to run on this?
  • [01:43:50] <levi> The thing about Angstrom is that it's based on an embedded systems development toolchain, which makes it far more convenient to extend and modify than Ubuntu. But if you're going to mostly be using pre-built kernels and packages and whatnot, I guess Ubuntu would work just as well.
  • [01:44:17] <xterm91> Is there a benefit to Angstrom over Gentoo?
  • [01:44:34] <levi> Gentoo is the last distro I would pick.
  • [01:44:55] <malcom2073> I typically use prebuilt kernels and packages heh
  • [01:44:58] <xterm91> Really? I had it install and update everything just fine... I'm just not used to the package manager
  • [01:45:25] <Ed22> levi -- i'd like ubunu on the emmc also -- how do i do that
  • [01:45:48] <MH> ssi hmm I'm not having any luck with your code either :/ the kernal you said you made that is only necessary for the gpio_leds right?
  • [01:46:05] <levi> I have no desire to put ubuntu on the emmc, so I haven't looked up how to do it.
  • [01:46:54] <levi> Gentoo is designed to build the packages that run on the machine on the machine itself. Why would you want to compile stuff on a little ARM CPU when you've got a far more powerful desktop or laptop handy?
  • [01:47:06] <ssi> MH: correct
  • [01:47:15] <ssi> MH: what's it doing?
  • [01:47:34] <xterm91> I'm new to this but distcc could be used, right?

  • [01:48:23] <levi> Possibly, but it seems like a lot more trouble than just using Angstrom, buildroot, geexbox, or one of the several other embedded Linux build systems.

  • [02:13:38] <xterm91> Wow that sounds crowded... glad I'm sitting off on an sd card
  • [02:15:31] <ptan> ok, most of the stuff taking up space is on ~/.npm
  • [02:15:59] <ptan> can someone with a clean BBB do an ls -a ~/.npm and let me know what it says?
  • [02:16:19] <ptan> I need to know what I can delete (or if I can delete it all)
  • [02:17:05] <ptan> or does anyone know how to prune npm properly?
  • [02:17:23] <Ed22> xterm when i make these partitions does size matter or boot like 70 megs and 3.9gb for root???
  • [02:17:56] <Ed22> i ll boot my BBBK and look at .npm
  • [02:18:03] <ptan> thanks
  • [02:19:49] <Ed22> where is .npm?
  • [02:19:53] <Ed22> dhat dir ?
  • [02:20:01] <ptan> should be in ~/.npm
  • [02:20:22] <ptan> /home/root/.npm
  • [02:20:34] <ptan> or do you not have a .npm directory?
  • [02:20:41] <Ed22> i dont have one !
  • [02:20:48] <ptan> ok, cool... that helps..
  • [02:20:52] <Ed22> doing a find ! find . -name '.npm'
  • [02:20:57] <Ed22> long wait
  • [02:21:06] <Ed22> nothing found
  • [02:21:34] <ptan> I was installing stuff in node.js using npm install <package>... so now that I know it is safe, I can just delete it all.
  • [02:21:38] <ptan> thanks.
  • [02:22:23] <xterm91> Ed22: boot will be only around 70 megs
  • [02:22:32] <Ed22> ok - i never invoked npm b4
  • [02:23:30] <ptan> I'm learning it now as I go along. Using npm to install stuff needed to get a web server running under node.js

  • [02:36:09] <ptan> MH: I would have, but after seeing everyone having problems with upgrading, I am going to wait for a while till the dust settles
  • [02:36:35] <MH> I had no problems upgrading with the angstrom distro, it is the other ones that are causing troubles.
  • [02:37:01] <MH> ptan it does take about 45 minutes for it to update, so you have to be patient
  • [02:38:20] <ptan> MH: is there much difference in the 3.8.6 Apr 13 version and the current version?
  • [02:39:32] <ptan> MH: where is the changelog anyway for it? my google-fu is failing me.

  • [03:00:59] <m_billybob> Galt, which kernel areyou upgrading to ? I had to do a opkg --force-overwrite install kernel-image-3.8.8

  • [03:01:11] <Galt> I am using a router as my wifi connection, and I am plugged into the boards Ethernet port. I can access the web fine!
  • [03:01:22] <Galt> I will try that thanks, let me see what happens.

  • [03:02:14] <ptan> Galt: m_billybob might be right, I'm waiting for the dust to settle before I upgrade my BBB
  • [03:03:11] <m_billybob> ptan that "unclean" install method is supposed to be fixed in 3.8.11 but no idea if thatmeans once you've upgrade future upgrades will work or if you can upgrade to that version and not have to do it . .
  • [03:03:12] <ptan> m_billybob: glad to know upgrades actually work without much fuss
  • [03:03:37] <m_billybob> i saw mention of it on the mailign lists either way

  • [03:04:21] <m_billybob> upgraded prior*
  • [03:04:34] <m_billybob> by liek a day
  • [03:04:53] <m_billybob> was told .10 was sort of hokie so i avoided it

  • [03:05:15] <ptan> m_billybob: should Galt upgrade to .11?

  • [03:07:44] <m_billybob> Galt uname -a whats it say ?
  • [03:08:06] <ptan> Galt: same here, new to angstrom, used to ubuntu/debian, doesn't look like any angstrom gurus are online.
  • [03:08:20] <Galt> That okay, I'm new to Angstrom, I know my way around Debian pretty well for the time I have been using it. I love linux, and I switched a year or so ago from Win
  • [03:08:37] <m_billybob> yeah i want to switch to debian myself CPI only with LAMP etc, but seems like angstrom is very similar to debian
  • [03:08:43] <levi> Angstrom is kind of debianish in flavor.
  • [03:08:46] <m_billybob> CLI only*

  • [03:10:11] <levi> It's a descendant of OpenZaurus, which was initially Debian.
  • [03:11:03] <m_billybob> ntp server seems to be failing, not sure why. got a cron job listed . . . timezone setup . .still nto working
  • [03:11:06] <levi> It then developed its own smaller packaging tools, though it continued to follow Debian conventions.
  • [03:11:33] <levi> It later got reused for projects like OpenWRT and other PDAs, and got renamed OpenEmbedded.
  • [03:11:34] <m_billybob> levi, would i be correct that opkg is basically a smaller version of apt ? or similar ?
  • [03:11:41] <Galt> I like the ease of the "setup_sdcard.sh" scrip, it makes burning the img to the sd card easy
  • [03:11:56] <xterm91> Galt: Have you gotten Android to work?
  • [03:12:02] <levi> It's not exactly like apt, it's sort of like dpkg+a bit of apt.
  • [03:12:50] <Galt> Gota go take my dog for a walk, I'll think on this. I tried the Android, and yes, I made a mistake, I could make the disk, but it didn't boot. That was the only one that doesn't work. I want that os though!!!
  • [03:12:57] <m_billybob> levi, oh cool, now i just need to figure out whcih packages are safe to remove :/ anyone know of a list ?
  • [03:13:13] <xterm91> Galt: If you get it to work please let me know...

  • [03:14:22] <Galt> Absolutely, this will be the first place I go to say anything!!!! I know that people are salivating to use jellybean on this puppy!
  • [03:14:45] <Galt> gotta go for a few, be back soon
  • [03:14:49] <levi> OpenEmbedded spawned a device-agnostic distro named Angstrom, and more recently it got its build and packaging system rebuilt to be even more device/distro agnostic. It's now based on OE-Core/Yocto and a layer system for adding hardware support packages, distribution policy, application packages, etc.

  • [03:20:17] <levi> galactic: You might try seeing if the USB modules corresponding to your keyboard and mouse are loaded (after you ssh in from a computer with a working keyboard and mouse)
  • [03:20:28] <xterm91> levi: I've heard that the Roku has issues playing Netflix in HD and I'm curious about the extensibility of it to other streaming services
  • [03:20:49] <galactic> hmm
  • [03:21:07] <galactic> ok
  • [03:21:34] <levi> galactic: You might also try unplugging them and re-plugging them.

  • [03:57:37] <m_billybob> yeah I figured as much
  • [03:57:49] <levi> That particular checkout command switches to a branch in the "origin" repository and makes a local branch that follows the remote one.

  • [03:59:56] * MH (18ffd573@gateway/web/freenode/ip.24.255.213.115) has joined #beagle
  • [04:00:48] <m_billybob> levi, but yes, looking over those "blog" type posts on gettign debian on the bbb, what you've pasted there has cleared a few question up that ive had. much thanks and most helpful :)
  • [04:01:28] <m_billybob> still dont know which distro we want to go with. we're most familiar wirth debian
  • [04:01:44] <m_billybob> im willing to give angstrom a shot though
  • [04:02:09] <m_billybob> seems to be the path of least resistance

  • [04:10:23] <levi> TI has a team that manages an OE layer for their devices, so OE-based distros can get all of their kernel patches and whatnot that way.
  • [04:11:32] <levi> You can manage your own software packages, kernel config tweaks, etc. in your own layer as well, which allows you to keep them separate from upstream-managed things.
  • [04:11:42] <levi> This makes porting your changes to new versions of things much easier.
  • [04:12:46] <m_billybob> seems that TI is usually very good with tools for their products.
  • [04:12:58] <m_billybob> this is what ive experienced so far anyhow
  • [04:13:20] <levi> Well, yes, they are better than many.
  • [04:13:31] <m_billybob> noticed a long time back they seemed to get a workign version of android for the sitara core processors fairly quickly
  • [04:14:16] <levi> Working with TI has its ups and downs, but they share the downs with most big companies.
  • [04:16:31] <m_billybob> being an embedded device hobbyist ( mostly programmer ) ive looked around at many devices on the market, and while TI isnt perfect, id wager they are probably one of if not the best with support. tools docs, etc
  • [04:17:02] <m_billybob> they do some thigns that boggle my mind too but heh, thats another story
  • [04:17:09] <levi> At work, I've been working with Pandaboards and also with a board designed in-house with a TI Jacinto (like an automotive version of an OMAP).
  • [04:17:50] * xterm91 (~xterm@pool-96-244-42-7.bltmmd.fios.verizon.net) Quit (Quit: Leaving.)
  • [04:17:51] <m_billybob> so you do this professionally then
  • [04:18:19] <levi> Yes, but the beaglebone stuff I'm doing is a hobby. :)
  • [04:19:37] <m_billybob> the bbb is goign to be a big step forme i think. im rusty with linux, and its a new type of software platform. meaning the msp430 where ive spent most of my time in the last few months has no OS . . . so yeah. I think once i figure out the software that i need, i may have to write a fewof my own kernel modules, whcih i know very little about, but do have a good book on the subject
  • [04:20:15] * [1]segfault dances i got all 11 of my BB flashed
  • [04:20:21] <[1]segfault> 0 problems
  • [04:20:33] <[1]segfault> 7 BB and 4 BBB
  • [04:20:40] <m_billybob> maybe might need a new mindset too. like with the msp430, using the hardware periphs is usually the best way to get thigns done. not sure abotu that on the bbb
  • [04:21:15] <levi> Their Pandaboard support started out very impressive, but things seemed to get very disorganized over time, and then TI decided to get out of the tablet/smartphone market and decimated their staff for supporting OMAP processors like the one in Pandaboard.
  • [04:21:48] <m_billybob> ah yeah i read about that, was wondering what it would bode for the beaglebone stuff
  • [04:22:06] <levi> Sitara is actually an industrial part, which is where they want to focus.
  • [04:22:22] <m_billybob> yeah
  • [04:22:51] <levi> So I think support for beaglebone is likely to continue. It helps that despite its complexity, it's vastly simpler than the OMAP parts.
  • [04:23:32] <m_billybob> but when they stated that, sicne i knew little abotu the different platforms i assumed it would have somethign to do with the beagleboards. thankfully i was wrong I think the beagleboards are probably the best platforms in their class. if not, i still feel that way about them
  • [04:23:54] <m_billybob> i have zero love for the rpi
  • [04:24:07] <m_billybob> havent touched one, and probably never will
  • [04:24:14] <m_billybob> not after what ive been reading
  • [04:24:25] <trip9> does anyone know if gpu acceleration is achievable on the beaglebone with the 3.8.x kernel?
  • [04:24:45] <levi> The original beagleboards have OMAPs, and fairly old ones at that. I imagine TI is going to focus more on the Sitara-based beaglebones.
  • [04:24:56] <m_billybob> trip9, no idea but id love to get coin mining working on one, jus tfor the hell of it
  • [04:25:05] <trip9> lol
  • [04:25:18] <trip9> i don't imagine it would mine bitcoins very fast
  • [04:25:21] <m_billybob> .0000001MH/s for the win !
  • [04:25:27] <m_billybob> no it wouldnt
  • [04:25:36] <trip9> but it could make a decent dlna-player
  • [04:25:40] <m_billybob> with a FPGA cape now, that'd be a different story
  • [04:25:46] <trip9> haha
  • [04:25:47] <levi> trip9: If by gpu acceleration you mean 3d graphics, then probably yes.
  • [04:25:50] <trip9> that'd be slick
  • [04:26:01] <trip9> levi, specifically the pvr drivers
  • [04:26:07] <m_billybob> trip9, looking at the list someone seems to be working on a spartan 6 cape too . ..
  • [04:27:26] <trip9> ooo
  • [04:28:27] <m_billybob> im not terribly "up" on the diferent spartan FPGA, but the LX150 is it ? can do !95MH/s
  • [04:28:38] <m_billybob> ~95MH/s
  • [04:29:04] <trip9> hmm, 95MH/s doesn't seem like a lot.
  • [04:29:26] <m_billybob> 4 + together though . ..at a fraction of the power cost of a dedicated GPU.
  • [04:29:52] <m_billybob> one problem though is that the price per FPGA is aroudn $175 US
  • [04:30:39] <m_billybob> anyhow i wouldnt do it for the money really, just would do it, to just do it
  • [04:30:43] <m_billybob> for the geek factor
  • [04:31:42] <m_billybob> you can buy an ASIC now days for ~$300 -> 5GH/s
  • [04:31:57] <m_billybob> well ASIC based bitminer
  • [04:32:46] <m_billybob> by the time they'll ship ( they're probably seriously backordered ) difficulty will probably be skyhigh

  • [04:35:02] <m_billybob> levi, so once i get a minimal install going, should be fairly standard to get a LAMP working, and the bonescript stuff id imagine ?

  • [04:35:52] * zeebar (~zeebar@184.69.101.202) Quit (Remote host closed the connection)
  • [04:35:58] <rbarris> keep an eye on free space in your onboard flash..
  • [04:37:37] <m_billybob> was noticing standard install that comes with the bbb is ~1.6G, i need no where near that mcuh, well technically i guess its not standard sicne ive since upraded to 3.8.8
  • [04:37:43] <levi> If you want bonescript, the recipe for it is in sources/meta-ti/recipes-misc/payload/bonescript.bb
  • [04:38:54] <levi> It's included in the cloud9-image recipe, which can be found in sources/meta-ti/recipes-misc/images/cloud9-image.bb
  • [04:38:57] <m_billybob> it seems to be useful, could use i2c SPI and UART on it, but meh. it's "free"
  • [04:39:08] <m_billybob> do i really need cloud 9 ?
  • [04:40:12] <levi> I'm not sure how integrated bonescript is with it.
  • [04:40:26] <levi> The build recipe in meta-ti depends on cloud9.
  • [04:40:37] <m_billybob> hmm ok
  • [04:41:02] <levi> It shouldn't be terribly heavy, since it runs on nodejs and so does bonescript.
  • [04:41:07] <m_billybob> maybe i could hack my way out of it if needed, but ill worry aboutthat later
  • [04:41:08] <m_billybob> yeah
  • [04:46:38] <levi> BTW, if your distro installs texinfo 5, it will save you some pain to downgrade it to texinfo 4 before you try building the angstrom stuff.
  • [04:47:27] <m_billybob> so noted, and added to my text file of refference :)
  • [04:48:18] <m_billybob> once i get good at this i may write an updated blog on it. if it wont help anyone else, atleast i can use it myself for future refference
  • [04:48:44] <levi> For some reason, texinfo 5 changed some stuff in its parser, so gcc and binutils fail to build their documentation.
  • [04:49:22] <m_billybob> hate it when that happens
  • [04:50:05] <levi> Also, note that you will want to have around 30Gb or so of free space available. The system builds a cross-toolchain, kernel, etc and doesn't delete any of its intermediate work products by default.
  • [04:50:08] <m_billybob> but been playign with FOSS for years now. come to learn the less you upgrade build tools of this nature, often the better off you are
  • [04:51:23] <m_billybob> starting to sound like i may want to dedicate my second laptop forthis purpose. similar to android in resources needed
  • [04:52:05] <m_billybob> levi, any idea the size of the repos that i'll need for minimal ?
  • [04:52:46] <m_billybob> 5-6GB perhaps ? only reason why i ask is our internet is kind of limited
  • [04:53:21] <m_billybob> will have to setup some form of rate limiting if its larger than a few hundred megabytes

  • [04:56:57] <ds2> hmmm
  • [04:57:38] <MH> 434mb for the angstrom image, if this is what your lookin for
  • [04:57:48] <m_billybob> cool thanks
  • [04:57:53] <levi> You shouldn't have any problem. The space explosion is due to the fact that source code compresses well, and then you have all the .o files, and then the binaries, and then the packages, and then the unpacked-packages in system directories, etc.
  • [05:02:36] <levi> There are some options to instruct it to clean up after itself as it goes.
  • [05:03:06] <m_billybob> where is the best place for clear documentation on the matter ?
  • [05:03:37] <m_billybob> ive foudn lots of stuff but most of it seem cryptic to me well not all of it but parts

  • [05:04:34] <m_billybob> cool
  • [05:05:40] <m_billybob> i dotn really mind though space isnt too much of a problem i have 1.5TB in this laptop, 500 on the other with an additional 120GB drive if i decided to go bare metal Linnux on that machine
  • [05:05:42] <levi> I would recommend going to www.yoctoproject.org and reading at least the Quick Start Guide.
  • [05:06:17] <levi> Angstrom adds a bit on top of it with their setup scripts, but the core stuff is the same.
  • [05:06:46] <m_billybob> read some of that several months ago
  • [05:07:33] <m_billybob> ive aleways been facsinated with embedded linux. started reading about openembedded a few years back. 2-3

  • [22:41:15] <ka6sox> currently most of the DAB I work with is 44.1 16bit
  • [22:41:18] * spavis (~spavis@24-107-225-154.dhcp.oxfr.ma.charter.com) has joined #beagle
  • [22:42:11] <ds2> ka6sox: why is it 44.1? (vs 48)
  • [22:42:31] <levi> Because CDs use 44.1
  • [22:42:37] <ka6sox> ds2, because unless you are in the studio doing nothing is 48khz
  • [22:42:47] <ka6sox> (or 96kb)
  • [22:42:48] <levi> Because they had to use 44.1 to fit a full album on a disc.
  • [22:42:54] <ds2> ka6sox: ohhh... I thought DAT's was the std?
  • [22:43:02] <mru> levi: not entirely true
  • [22:43:12] <mru> a CD holds more than an LP
  • [22:43:31] <ka6sox> what levi said is true...the CD mastering process is all 44.1
  • [22:43:33] <mru> ds2: DAT is 48kHz
  • [22:43:36] <levi> It would hold less than it does if it used 48khz sampling instead of 44.1.
  • [22:43:49] <ds2> mru: yes, hence that's why I thought 48KHz would be more common
  • [22:44:01] <mru> yes, but an LP is only ~40min while a CD is 70min
  • [22:44:05] <ds2> 48KHz is a nice mulitple of 8KHz
  • [22:44:14] <ds2> fits well on a T1
  • [22:44:14] <mru> going from 44.1 to 48 would still allow a full LP
  • [22:44:24] <ka6sox> ds2, for recording they use 48/96
  • [22:44:31] <ssi> LP can be as long or short as you want depending on the output level you're willing to tolerate
  • [22:44:33] <ka6sox> but for mastering its *all* 44.1
  • [22:44:39] <mru> a lot of it has to do with thing being nice multiples of other thingss
  • [22:44:41] <ds2> I see
  • [22:44:47] <mru> especially when video is involved
  • [22:45:11] <ds2> which then has a lot of to do with local powerline freq ;)
  • [22:45:15] <mru> you want the audio and video clock ratio to be a nice rational number

  • [22:45:42] <ka6sox> so how did ATSC get to be 19.39Mb aggregate :P
  • [22:45:49] <levi> A lot of really screwy stuff ends up being related to how screwed up video is.
  • [22:45:59] <ka6sox> probably what they could fit in 6mhz with 8vsb
  • [22:47:13] <ka6sox> levi, the muxes for TV transmission do bitstealing on the fly...its scary.
  • [22:47:28] <mru> the 59.94fps thing has to do with interference patterns between the chroma subcarrier and the 60Hz power line
  • [22:48:17] <ka6sox> no moire patterns on your TV
  • [22:48:19] <ds2> and that it is close enough that existing B&W tv sets can lock into it
  • [22:48:24] <prpplague> biot: ping
  • [22:48:33] <biot> prpplague: pong
  • [22:48:37] <ka6sox> ds2, um....what decade are you living in?
  • [22:48:44] <levi> So, I guess the bit about the LP length is indeed a bit of 'folk history'. At least according to Wikipedia, 44.1kHz is mostly due to VCR PCM adapters.
  • [22:48:51] <ds2> ka6sox: that comes from when NTSC started
  • [22:48:54] <ka6sox> existing BW tv sets dont' exist...
  • [22:48:57] <ka6sox> oh right
  • [22:49:04] <prpplague> biot: quick, any usb temp loggers you recommend that work with sigrok?
  • [22:49:05] <ka6sox> but today we don't think in terms of NTSC.
  • [22:49:12] <levi> Video is still controlled by the legacy of B&W television.
  • [22:49:18] <levi> It's scary.
  • [22:49:21] <ds2> yes but NTSC rears its legacy
  • [22:49:37] <ka6sox> NTSC will be gone in 2016
  • [22:49:46] <ds2> 'chroma subcarrier' is the ~3.57MHz color burst, right?
  • [22:49:54] <ds2> long live NTSC :D
  • [22:50:03] <ka6sox> yes, 3.579mhz
  • [22:50:10] <biot> prpplague: we only support two currently, both cheap stuff: the lascar EL-USB series and the MIC 9858x
  • [22:50:42] <prpplague> biot: ahh
  • [22:50:46] <mru> btw, a few years ago in a hotel I randomly ran into one of the guys who invented ntsc
  • [22:50:54] <mru> that was interesting

  • [22:51:22] <ds2> mru: did he argue for or against "compatible" color?
  • [22:51:36] <mru> he admitted pal did a better job
  • [22:51:48] <mru> but they were the first to do it at all
  • [22:51:52] <biot> prpplague: that seems VERY expensive for a bunch of thermocouples
  • [22:51:53] <ds2> PAL is at 4MHz subcarrier, right?
  • [22:51:57] <ka6sox> except for the flicker of 50hz crud
  • [22:52:09] <mru> ds2: there are many variants of pal
  • [22:52:15] <ds2> PAL-UK
  • [22:52:29] <ka6sox> how about SECAM?
  • [22:52:31] <ds2> I know some places have PAL with 3.57MHz, IIRC
  • [22:52:41] <mru> ka6sox: pal with a french twist
  • [22:52:41] <ds2> isn't that a frog problem?
  • [22:53:00] <ka6sox> ya, gotta be just different to say "NIH" to PAL :P
  • [22:53:04] <mru> what pal does is solve the drift problem
  • [22:53:12] <ka6sox> yup
  • [22:53:21] <levi> I was astounded when I first discovered that digital video over DVI/HDMI is clocked just like analog video is.
  • [22:53:22] <ka6sox> however that should be gone by now
  • [22:53:23] <ds2> so that's why pal is PAL and not Never The Same Color?
  • [22:53:38] <mru> indeed
  • [22:54:00] * mru thought it was Never Twice Same Color
  • [22:54:21] <ds2> ah yes
  • [22:54:56] <mru> and you had a knob to adjust it
  • [22:55:49] <levi> DisplayPort is finally moving away from fixed-clock video transmission.
  • [22:55:56] <mru> uh?
  • [22:56:26] <mru> dp is packet based, yes
  • [22:56:37] <mru> but there's still a pixel clock
  • [22:56:43] <levi> Well, the clock rate of data transmission is not the video clock.
  • [22:56:55] <mru> there'd better be a relation
  • [22:57:03] <mru> or you'll be losing frames
  • [22:57:07] <mru> or duplicating them
  • [22:57:29] <ds2> you don't want the receiver to be buffering it?

  • [22:59:52] <mru> it works in the sense that it keeps numerous people in employment
  • [22:59:53] <levi> I'm not clear on exactly what clock drives the DP transmission, but clocks for video and audio data are recovered from data embedded in the stream packets.
  • [23:00:45] <mru> I haven't read the dp spec in detail, but the transmitted video data and the displayed images must be somehow synced up
  • [23:01:39] <mru> of course if your link clock is high enough, you can insert a gap between video packets

  • [23:45:16] <BrickedAlready> That's exactly my problem. I'll think I'll avoid angstrom from now on.
  • [23:45:45] <BrickedAlready> Any distro recommendations?
  • [23:45:48] <thurgood> angstrom isn't the problem specifically
  • [23:46:16] <thurgood> did you see instructions telling you to run `opkg upgrade` anywhere?

  • [23:46:34] <terisk> BrickedAlready: angstom isn't all bad. just need to work out some issues.
  • [23:46:43] <thurgood> it's like a little red shiny button I suppose
  • [23:47:00] <terisk> thurgood: "ooo, latest and greatest"
  • [23:47:11] <thurgood> it does seem like it would solve potential problems if you've never tried it before
  • [23:47:17] <BrickedAlready> yeah. I use arch on everything else, so its an impulse of mine to update when I can.
  • [23:47:36] <mru> levi: at the lowest level, the pixels are updated one at a time by row/column
  • [23:47:36] <thurgood> but I've never seen instructions telling people to actually use it
  • [23:47:43] <PRU_EVTOUT_2> opkg update always fails for me if i don't specify a temp dir.
  • [23:47:50] <mru> but exposing that level of control would need thousands of wires
  • [23:47:55] <mru> width+height
  • [23:48:01] <mru> that's not practical
  • [23:48:28] <mru> so pixels are sent serially into some control circuitry that distributes them properly
  • [23:49:03] <BrickedAlready> BTW, the guys having the LCD argument. You'll either access the pixels using multiplexing or serially. You'll have a rough time finding a display that lets you access them individually.
  • [23:49:13] <BrickedAlready> Who's asking?
  • [23:49:21] <thurgood> btw, BrickedAlready I'm not intending to be insulting... I've run it too expecting good things
  • [23:50:23] <PRU_EVTOUT_2> what would be the benefit of single access? just do single access into teh frame buffer. who cares what the lowest possible level of the hardware is doing.
  • [23:50:33] <BrickedAlready> thurgood: No offense taken. I just have to go warn my peers before we have to flash all four of these.
  • [23:50:42] <mru> PRU_EVTOUT_2: that's what I'm saying
  • [23:50:55] <thurgood> fair enough
  • [23:51:01] <mru> and it's usually more practical to have the framebuffer locally
  • [23:51:03] <levi> If you're doing video, sure, you want to refresh the entire panel at your video rate.
  • [23:51:07] <mru> there are remote framebuffer displays
  • [23:51:23] <mru> but that's really only practical for rather limited resolutions
  • [23:51:39] <mru> or low refresh rates
  • [23:52:00] <levi> But if the panel were self-refreshing, and you could update only portions of the screen, you could display GUIs and whatnot at high resolution without a powerful processor.
  • [23:52:22] <mru> you just described a graphics card

  • [23:52:34] <PRU_EVTOUT_2> wait, what does processor power have to do with video?
  • [23:52:56] <mru> it's almost always more practical to have the frambuffer local
  • [23:53:02] <thurgood> on the beagle...?
  • [23:53:10] <mru> and scan it out over some link or other
  • [23:53:12] * NoProblem (~NoProblem@cpe-184-57-132-151.cinci.res.rr.com) Quit (Quit: Leaving)
  • [23:53:17] <PRU_EVTOUT_2> the video hardware is responsible for clocking out the physical signal, not the processor. all the processor should do is modify a chunk of memory....the frame buffer.

  • [23:53:53] <PRU_EVTOUT_2> although...bitbanging video signals is fun.

  • [23:55:40] <levi> Well, I do think up crazy stupid ideas sometimes. Fortunately, I don't tend to hold on to them once I figure out they're stupid.
  • [23:55:56] <mru> there are interfaces like mipi dsi
  • [23:57:53] <mru> but remote framebuffer interfaces in general end up sending more data across the link than a simple pixel stream would
  • [23:57:57] <mru> for a full-frame update
  • [23:58:42] <mru> and you almost always end up with a shadow framebuffer anyway
