  • [00:03:52] <ds2> where are you reading from?
  • [00:04:03] <jay6981> 0
  • [00:04:20] <ds2> and on what basis are you expecting an exception?
  • [00:04:47] <mru> crash not exceptional enough for you?
  • [00:05:04] <jay6981> well??? the code stops running, so I figured it stopped because of an exception
  • [00:05:53] <ds2> does the vectors default to down load or up somewhere high up?
  • [00:06:03] <ds2> seem to recall one of the sysboot pins has a say in that
  • [00:06:13] <jay6981> that's what I'm trying to figure out???
  • [00:06:30] <mru> the omap3 boots with low exception vectors
  • [00:06:32] <ds2> mru: are you so sure about the no? ;)
  • [00:06:33] <jay6981> the SCTLR shows them mapped low, but VBAR is also set to 0x14000
  • [00:06:39] <mru> the boot rom is mapped at address 0 on reset
  • [00:06:57] <jay6981> i think the rom is at 0x14000
  • [00:07:02] <ds2> the omap3 or the beagle? I am almost sure one of the sysboot pins can change that
  • [00:07:06] <mru> that's where it goes later
  • [00:07:09] <mru> or not
  • [00:07:11] <jay6981> omap3
  • [00:07:27] <mru> it goes to 0x4xxxxxxx

  • [00:07:40] <ds2> sysboot 6 or 5... one messes with the boot addrs and the other screws with the oscillators
  • [00:07:40] <mru> beagle is omap3
  • [00:08:02] <ds2> no, I mean beagle specific config of the sysboot lines or is that hard wired into the omap3
  • [00:08:23] <mru> the boot sequence is hardwired in the omap3
  • [00:08:46] <ds2> let me find the TRM
  • [00:09:01] <jay6981> maybe i'm not reading it right, but the TRM shows sysboot pins only affecting which devices to try to boot from
  • [00:09:57] <jay6981> 25.2.3 Boot Configuration
  • [00:09:57] <jay6981> Six external pins (sys_boot[5:0]) are used to select interfaces or devices for booting. The sys_boot[6] pin is used to select whether the internal oscillator is bypassed.
  • [00:10:04] <ds2> look at the sysboot5 line description
  • [00:10:13] <ds2> it effects the rom mapping and gpmc interactions
  • [00:10:32] <ds2> sysboot6 is the osc control pin
  • [00:10:46] <ds2> sysboot 0:4 effects the boot device and ordering
  • [00:11:55] <jay6981> i'm looking for it, but don't see where sysboot6 is described
  • [00:12:02] <ds2> it is in the TRM
  • [00:12:16] <ds2> are you using the DM3730 or the OMAP3530 one?
  • [00:12:35] <mru> the 3630 one might be more detailed
  • [00:12:36] <mru> or less
  • [00:12:38] <mru> it's a bit random
  • [00:12:45] <ds2> I am looking at the dm3730 one as that's what I have on my laptop right now
  • [00:13:03] <ds2> I suspect sys_boot5 lets you do more low level stuff with NOR on the GPMC
  • [00:13:36] <mru> I was under the impression the internal rom always runs first no matter what
  • [00:14:52] <jay6981> omap3530
  • [00:15:01] <ds2> "When booting from the GPMCwith the appropriate external sys_boot5 pin configuration the memory space is part of the GPMC space"
  • [00:15:08] <jay6981> this is all I can find: ??? The sys_boot[5] pin defines which group of booting sequences is preferred: memory booting (sys_boot[5] = 0) or peripheral booting (sys_boot[5] = 1).
  • [00:15:21] <ds2> jay6981: what chapter?
  • [00:15:32] <jay6981> 11.1.3.3.2
  • [00:15:40] <ds2> both NAND and eMMC are not directly bootable
  • [00:15:42] <jay6981> i also see the blurb you posted too
  • [00:16:11] <ds2> u should've asked this last week when I researched it to verify a design :D

  • [00:16:41] <ds2> the question to ask is how is what needs to be done for NOR boot.
  • [00:17:40] <jay6981> this can boot off mmc??? its an overo board
  • [00:17:45] <mru> the rom code can probably jump to something in NOR once it's done with its business
  • [00:18:24] <jay6981> the booting part i've got working??? i can run my code??? just can't seem to get it to run my exception vectors
  • [00:18:58] <mru> then you're just holding it wrong
  • [00:19:00] <jay6981> i've tried loading my vectors into the RAM indirect locations specified by the TRM, no luck
  • [00:19:18] <jay6981> i also tried repointing VBAR at my vector table??? no luck there either
  • [00:19:36] <ds2> RAM indirect?
  • [00:19:46] <ds2> didn't think the ROM knowns about where RAM is
  • [00:20:07] <mru> rom obviously can't know about ram
  • [00:20:09] <jay6981> as described by section 25.4.2.2
  • [00:20:19] <mru> since rom is fixed and you can use any ram chip you please
  • [00:20:29] <jay6981> i'm talking about on chip SRAM,
  • [00:20:35] <jay6981> i should have been more clear
  • [00:20:41] <mru> once ram is configured, you can of course put the exception vectors there
  • [00:20:42] <ds2> I suppose it can enforce RAM to be at a certain based address/chipselect
  • [00:20:59] <mru> ram always starts at 0x80000000
  • [00:21:07] <mru> physical
  • [00:21:13] <jay6981> i haven't gotten so far as to turn on main memory yet
  • [00:21:15] <ds2> thought that is moveable with the chipselect base?
  • [00:21:28] <ds2> i.e. if I am insane enough to put in 128M of SRAM
  • [00:21:52] <jay6981> my code loads at 0x40200000
  • [00:22:12] <jay6981> the bootrom is kind enough to shadow it there from the SD card
  • [00:22:18] <mru> ds2: the dram controller maps 1GB starting at 0x80000000

  • [00:22:46] <mru> gpmc uses another region
  • [00:22:51] <mru> but still fixed
  • [00:22:57] <ds2> okay
  • [00:23:02] <ds2> but ROM can't predict which I have

  • [01:30:55] <bobkatzz> ok ds2 - I'll give the serial thing a go - I have a USB/Serial adapter here I think
  • [01:30:56] <MrBIOS-seamicro> ds2, LVDS rather
  • [01:31:22] <ds2> oh... LVDS is conceptually straight forward
  • [01:31:35] <ds2> just keep the DS wired up right for SI reasons
  • [01:31:53] <MrBIOS-seamicro> that part just flew over me
  • [01:31:55] <bobkatzz> when I was trying to get the monitor resolution fixed I must have screwed something up heh
  • [01:32:11] <ds2> bobkatzz: just fix the resolution in the kernel if you have to.
  • [01:32:17] <ds2> or use a proper display like a LCD panel ;) heheh
  • [01:32:18] <MrBIOS-seamicro> I have a handful of older SGI 1600SW displays which I'd like to drive with the BeagleBoard
  • [01:32:36] <bobkatzz> I never could see the menus completely - just the lower 10% but at least I could get into them off the screen and open them up

  • [01:32:54] <MrBIOS-seamicro> ds2, have you worked with LVDS?

  • [13:12:27] <jan_> hi
  • [13:14:57] * koen wonders why angstrom is 3rd party
  • [13:15:10] <koen> it ships in the box on beagle and bone
  • [13:17:29] <Alistair> Sorry! I mean in comparison to TI's EZSDK
  • [13:18:10] <Alistair> I know it's fairly simple to hook up EZSDK to CCS but will it be a similar process for the shipped angstrom?
  • [13:32:39] <_av500_> how do you hook it?
  • [13:36:26] <Alistair> What I mean is, There's the Remote System Explorer plugin, is connecting this to the angstrom distro a similar process?
  • [13:39:14] <koen> ka6sox: 20x20mm extrusions ordered!
  • [13:39:42] <koen> the ezsdk rootfs is based on angstrom
  • [13:39:49] <koen> so I'd call that 3rd party :)
  • [13:44:14] <Alistair> haha ok ok, but I guess my ultimate question is, would I expect any further steps to be needed to configure CCS with BeagleBone Angstrom vs the EZSDK customisation of it
  • [13:45:06] <Alistair> Is it still not possible to use the OE compiler on windows by the way for cross-compile?
  • [13:45:19] <koen> no, use linux if you developer for linux
  • [13:46:20] <mru> any decent unix should work
  • [13:46:30] <Alistair> harsh! I'm just fine with the command line in linux but when it comes to getting around a GUI quickly then it's windows for me, as much as I've tried to get comfy with ubuntu
  • [13:46:48] <mru> if you wanted to write iphone apps, you'd be forced to use a mac
  • [13:46:52] <mru> how is this any worse?
  • [13:47:09] <mru> at least we don't make you pay for the privilege
  • [13:47:20] * koen tried to use OE on his mac today, didn't work since HFS+ is case insensitive :(
  • [13:47:31] <mru> koen: so that's not a decent unix
  • [13:48:04] * unsolo_ (~unsolo@58.80-203-72.nextgentel.com) Quit (Read error: Connection reset by peer)
  • [13:48:04] <mru> vague words like "decent" can make almost any statement true
  • [13:48:08] <Alistair> Haha I did buy a Mac just for that, now I tend to use engine I can work with in windows and just pass over to mac for compile
  • [13:48:28] <Alistair> and mostly my Mac is left running windows with bootcamp
  • [13:48:33] <Alistair> big waste of cash
  • [13:49:36] <Alistair> but what I can say for mac is that the XCode and iOS experience is already configured from the start, as I'm not comfy with linux, this is the source of my concern
  • [13:50:42] * koen run linux in vms on his mac :)
  • [13:54:22] <Alistair> here's a question then, would I be correct in saying to setup cross compile with CCS I just download the rootfs for the BeagleBone angstrom and point to the compilers and libraries in there with CCS? Or am I perhaps missing a step
  • [13:58:53] <koen> forget ccs
  • [13:59:08] <koen> go to the angstrom webite, click 'developers' and follow the instructions

  • [14:04:14] <unsolo> is omap3_beagle_default config for 2.6.34.7 broken ? im getting zero console output on ttyS2
  • [14:04:38] <Alistair> one thing I did spot is that PRU examples wont be making it into the November EZSDK, do you know if TI have made available the general assembler or is this also delayed?
  • [14:04:51] <unsolo> booting of a mmc maybe i need to have a ramdisk too.. ?
  • [14:05:04] <koen> Alistair: forget about the ezsdk if you're using beagle or beaglebone
  • [14:05:23] <koen> Alistair: you don't even get NEON and VFP support with the current ezsdk
  • [14:05:55] <Alistair> @koen I've got you and I will (wow on the neon)
  • [14:06:18] <koen> Alistair: if you want to use a TI SDK on the beaglebone, use the AMDSK, that one is much, much better than the ezsdk

  • [14:09:20] <Alistair> @keon because I'm new to linux, a pipeline that makes remote debugging and transfer of files easier is very much appreciated
  • [14:10:51] <koen> if you use linux and plug in the beagle it will show up in the file manager automatically
  • [14:11:03] <koen> (provided you're running angstrom on the beagle)
  • [14:11:17] <unsolo> hmm i wonder if you could use the beaglebone as a openocd server..
  • [14:11:24] <koen> no need for a 1980s style nfs setup
  • [14:11:53] <Alistair> @keon haha, yeah I tried that with the pandaboard and opted for hosting a local webserver instead, never wanted to work

  • [14:29:47] <unsolo> something fishy about that linux uncompression
  • [14:29:53] <unsolo> i have my reasons
  • [14:31:05] <jan_> has anyone compiled a wifi module for the beagleboard?
  • [14:31:55] <unsolo> 2.6.34 is one of the longterm releases iirc.
  • [14:31:59] <mru> yes, someone has
  • [14:32:11] <koen> jan_: the angstrom kernel has pretty much all of them turned on by default
  • [14:32:37] <koen> unsolo: LTS doesn't buy you anything if the platform lacked decent support in that release
  • [14:32:43] <jan_> for some reason the ar9170 module is not included in the angstrom bb opkg rep
  • [14:32:56] <jan_> now i am fighting with compat-wireless to compile the module
  • [14:32:57] <unsolo> koen: 2.6.34 has quite a lot of support on the omap
  • [14:33:14] <unsolo> ret off and idle was merged to it
  • [14:33:14] <jan_> i was just wondering if someone has some experience with that
  • [14:33:57] <koen> unsolo: apart from handwaving about LTS, any other reasons?
  • [14:34:07] <koen> unsolo: 3.0.9 runs really well on my beagleboard here

  • [15:50:14] <unsolo> just asking to see at which stage if any where something even considered done specially in order to handle dm37xx cpu's
  • [15:50:55] <unsolo> actually the changes arent omap specific
  • [15:50:57] <unsolo> they are arm
  • [15:51:33] <mru> most of the arm errata stuff is irrelevant on the omap due to the rom lockout from secure mode
  • [15:51:43] <mru> the fixes can only be applied in secure mode
  • [15:51:57] <koen> ka6sox: in the UK
  • [15:51:59] <unsolo> mru: so the neon vfp deadlock ?
  • [15:52:06] <mru> which one?
  • [15:52:07] <unsolo> is a secure thing ?
  • [15:52:16] <unsolo> ARM Cortex-A8 r3p2 implements bug fixes that have been found in Cortex-A8 r2p3 and intermediate releases to r3p2. New revision used in AM/DM37xx comes with additional L1 cache memories. Data and instruction caches have been extended from 16KB each to 32KB each. This update has an impact on cache management software.
  • [15:52:48] <unsolo> 430973, 451027 and 621766 got fixed
  • [15:52:59] <unsolo> 430973: Stale prediction on replaced interworking branch causes Cortex-A8 to execute in the wrong ARM/Thumb state
  • [15:53:02] <unsolo> 451027: Neon loads or stores may incorrectly report a precise data abort under certain conditions
  • [15:53:05] <unsolo> 621766: Under a specific set of conditions, executing a sequence of NEON or vfp load instructions can cause processor deadlock
  • [15:55:07] <unsolo> so it seems one of the 3 work arounds in the kernel is fixed in dm37x

  • [16:40:25] <_av500_> but what is see is ppl taking N arm cores, adding the mhz and telling that is will kill x86 because it uses so few watts
  • [16:40:45] <unsolo> _av500_: my point is that i no longer need a FAN
  • [16:40:56] <unsolo> which is what is currently killing me in the background
  • [16:40:59] <_av500_> unsolo: nobody likey you :)
  • [16:41:10] * mru used to have a fanless intel-based laptop
  • [16:41:17] <mru> still have it actually
  • [16:41:19] <mru> just don't use it
  • [16:41:24] * _av500_ has a fanless x86 tablett
  • [16:41:25] <mru> wifi kind of burned up
  • [16:41:31] <_av500_> -t
  • [16:41:35] <unsolo> i have a via C3 and a AMD ..
  • [16:42:34] <unsolo> 1Ghz and 500mhz.. the via has a huge cooler. the amd geode is just to slow
  • [16:42:44] * _av500_ still has some AMD nor flash, good stuff
  • [16:42:56] <_av500_> all 512kb
  • [16:43:03] <unsolo> haha
  • [16:43:32] <_av500_> i heard these days they even managed to put a cap on the raw silicon and add a thermal diode...
  • [16:43:40] <jan_> let's say i want to compile my own kernel module on the bb with angstrom, what packages do i need? (opkg install kernel-headers?)
  • [16:44:01] <unsolo> jan_: why not compile it outside the board ?
  • [16:44:14] <unsolo> just do not do the same fup i did last night
  • [16:44:21] <_av500_> unsolo: x86 allergy :)
  • [16:44:36] <ssvb> _av500_: these dudes seem to claim to be 3x more power efficient than intel xeons for the server/desktop level of performance: http://www.brightsideofnews.com/news/2011/10/31/appliedmicro-shows-worlds-first-64-bit-arm-processor.aspx
  • [16:44:55] <jan_> unsolo: i thought maybe it's easier, directly on the board. you would recommend cross-compiling?
  • [16:44:56] <unsolo> _av500_: actually its more the how things are designed around arm rather than x86 vs arm tbh
  • [16:45:12] <_av500_> ssvb: too bad desktop cannot be measured
  • [16:45:26] <unsolo> arm + dsp like the omap is just so much better than doing instruction reordering to decode tomorrows codecs
  • [16:45:32] <ssvb> _av500_: but as mru says, promises are nothing until we see it for real :)
  • [16:45:49] <_av500_> unsolo: most of these codecs are hardcoded
  • [16:45:53] <ka6sox> so does machine=beaglebone bitbake virtual/kernel really build the world? because its over 8hrs and still going.
  • [16:46:01] <unsolo> jan_: i would .. if its the beagle
  • [16:46:07] <_av500_> unsolo: see omap4, it does 1080p hp, but cannot do vp8 720p
  • [16:46:13] <_av500_> on the "dsp"
  • [16:46:28] <unsolo> _av500_: id bet thats bad code + bad utilizatio
  • [16:46:30] <unsolo> +n
  • [16:46:32] <_av500_> nope
  • [16:46:39] <_av500_> its hardware
  • [16:46:44] <mru> omap4 can do vp8 720p in sw
  • [16:46:48] <_av500_> yes
  • [16:46:51] <unsolo> haha
  • [16:46:56] <unsolo> then i return to bad code.
  • [16:47:03] <_av500_> no
  • [16:47:09] <_av500_> fixed hardware units
  • [16:47:16] <mru> iva is not exactly a hw decoder
  • [16:47:25] <mru> it's software, just very special processors
  • [16:47:30] <_av500_> mru: you know exaclty what i mean
  • [16:47:41] <_av500_> the hw units cannot be used for vp8
  • [16:47:42] <ka6sox> so if its software then its fixable.
  • [16:47:42] <mru> it is probably possible to do vp8 oniva
  • [16:47:58] <_av500_> ka6sox: the sw runs on 2x M3
  • [16:48:06] <_av500_> have fun
  • [16:48:09] <mru> if it can do vp6 and h264, chances are high it can do vp8 too
  • [16:48:20] <mru> and 2x 968
  • [16:48:22] <ka6sox> I didn't say it was *easy*
  • [16:48:22] <_av500_> mru: ti thinks otherwise
  • [16:48:25] <mru> and the special processors
  • [16:48:28] <unsolo> if you did it partially in neon partially in c64x (provided you have a dsp) and maybe use some opengles as well im damn sure its possiblke
  • [16:48:31] <jan_> unsolo: ok, i will try that. thanks. (i have a c4 beagleboard)
  • [16:48:31] <unsolo> -typos
  • [16:48:34] <unsolo> bbl duty calls
  • [16:48:47] <_av500_> unsolo: no need, a9 does it already on its own
  • [16:48:56] <mru> _av500_: the tranform, mc etc blocks are also software
  • [16:49:08] <_av500_> dont think so
  • [16:49:14] <mru> I know so
  • [16:49:18] <_av500_> theres dct units in hw
  • [16:49:20] <_av500_> no?
  • [16:49:21] <mru> I have the instruction set docs

  • [16:50:09] <_av500_> anyway, the argument was "arm + dsp like the omap is just so much better than doing instruction reordering to decode tomorrows codecs"
  • [16:50:53] <_av500_> and apart from vp8, "tomorrows" codecs are usually an order of magnitude more comples
  • [16:50:56] <_av500_> complex
  • [16:51:08] <_av500_> and even vp8 cannot be done easily on the ivahd
  • [16:51:18] <_av500_> although is less complex than h264
  • [16:51:21] <mru> that's because TI don't want to
  • [16:51:28] <mru> trm says it can do vp7
  • [16:51:29] <_av500_> maybe
  • [16:51:34] <mru> and h264
  • [16:51:35] <ka6sox> resources
  • [16:51:35] <_av500_> it does
  • [16:51:36] <mru> and vc1
  • [16:51:39] <_av500_> yes
  • [16:51:41] <mru> and realvideo
  • [16:51:51] <mru> vp8 isn't too different from those
