  • [00:03:32] <djsmith> Greetings everyone.
  • [00:04:38] * rcn-ee (~voodoo@thief-pool1-30.mncable.net) has joined #beagle
  • [00:05:13] <djsmith> I am having a problem with my Lucid 10.04 image. The network interface usb0 does not appear to work. It does work under Angstrom, however. Any ideas on this?
  • [00:06:04] <rcn-ee> djsmith, which kernel? Does it show up with? "sudo ifconfig -a"
  • [00:06:30] <djsmith> rcn-ee: Linux beagleboard 2.6.32.11-l13 #1 PREEMPT Tue Apr 13 04:25:20 UTC 2010 armv7l GNU/Linux
  • [00:06:34] <djsmith> Yes, the interface appears with ifconfig -a.
  • [00:06:58] <Ikarus> hrm, silly question, anyone tried to hook up multiple SD cards to the beagleboard, multiplexed on a single MMC/SD pin set that is (just a unique chip select GPIO pin for each) ?
  • [00:07:14] <Ikarus> and if not, anyone know what I should watch out for if I want to implement it myself
  • [00:08:11] <rcn-ee> okay... yeah we had a discussion on that yesterday on the email list.. it seems to work better with a different config setting.. use this uImage and modules: http://rcn-ee.homeip.net:81/dl/testing/usbnet/ (i'm fighint a lucid gcc bug so i dont' have native *.deb's yet)
  • [00:08:50] <djsmith> Ah yes, I saw that discussion. About your URL, I know what to do with the uImage,b ut what do I do with modules.tar.gz?
  • [00:09:10] <djsmith> (just extract it over my /lib/modules?)
  • [00:09:39] <rcn-ee> just untarr it directly into your root file system ... it's all "/lib/modules/2.6....."
  • [00:10:25] <rcn-ee> tester just said he was able to ping so, so i'm assuming it worked beyond that too.. (cross fingers..)

  • [00:10:57] <djsmith> I'll have a go tomorrow when I get back into work. In the mean time, does the 9.10 image suffer from the same problem?
  • [00:12:20] <DanaG> ah, the "eem" not working?
  • [00:12:27] <DanaG> It was amusing using wireshark on that.
  • [00:13:29] <djsmith> What's the preferred method of cross-compiling software for this version of Ubuntu? I'm running Lucid on my PC.
  • [00:13:39] <rcn-ee> yeap... (i run the same kernel config for all debian/ubuntu variants..)
  • [00:13:48] <djsmith> I have been working on a Qt (command line) app that I want to cross-compile for the Beagleboard running Ubuntu.
  • [00:14:40] <rcn-ee> use angstrom's compiler... (even thou lucid is 4.4.3 and angstrom's is 4.3..) there's a blueprint in maverick for a ubuntu cross compiler..
  • [00:14:59] <djsmith> (by the way, when I wireshark usb0 on my host PC and ping the host from the Beagleboard, I get no packets)
  • [00:15:58] <djsmith> rcn-ee: Is there a HOWTO to get started? I've used buildroot in the past to build the toolchain, but Angstrom and OpenEmbedded are foreign to me.
  • [00:16:32] <DanaG> djsmith: no packets at all? that's odd... when I tried it, I got framing-error-ish garbage.

  • [00:22:52] <DanaG> I wish the beagle xm would do gigabit....
  • [00:22:54] <Ikarus> djlewis: and no, I won't use USB for it
  • [00:23:11] <DanaG> or there were that marvell ebox.... right now it's just a concept product.
  • [00:24:25] <djlewis> Ikarus, well other than that and what emeb is working on, I am unaware of any other multiple SD work
  • [00:24:45] <Ikarus> emeb ?
  • [00:25:29] <Ikarus> (ie, what is emeb working on)
  • [00:25:36] <djlewis> he built a fpga card with a SD socket, Not sure what it does. Attaches to BB
  • [00:25:40] <Ikarus> ah
  • [00:25:50] <Ikarus> probably loads the FPGA code from SD
  • [00:26:00] <Ikarus> guess I'll be tinkering on my own :)

  • [00:26:12] <djlewis> sorry I could'nt help
  • [00:26:13] <DanaG> Good luck using the Xilinx tools ON the beagle...
  • [00:26:23] <Ikarus> djlewis: np
  • [00:26:28] <DanaG> They're x86 / x86-64 only.
  • [00:26:28] <Ikarus> djlewis: I know roughly what is needed
  • [00:26:36] <DanaG> Even with SPI... how do you load the fpga?
  • [00:26:53] <Ikarus> DanaG: the protocol for loading SRAM FPGAs is documented
  • [00:26:58] <Ikarus> the bitstream format just isn't
  • [00:27:01] <Ikarus> but the tools output that
  • [00:27:45] <Ikarus> guess I'll have to patch the SD driver with some additional locks to avoid simultaneous access to a single MMC and have it store the card ID it needs
  • [00:27:53] <DanaG> ah.
  • [00:27:58] <Ikarus> the hardware is pretty simple, SD cards tristate when they don't get CS
  • [00:28:09] <djlewis> mmMmm, chili, cold tater salad and beer :)
  • [00:28:29] <Ikarus> so I just need a multiplexer IC to control CS
  • [00:28:38] <Ikarus> and mmc 1 is on the expansion connector
  • [00:28:47] <Ikarus> which is designed to hook up to cards directly
  • [00:28:56] <Ikarus> if I am not mistaken
  • [00:28:58] <emeb> hmmmm- my ears are burning...
  • [00:29:58] <emeb> The board w/ the microSD is not for use with Beagle - just an example of SMD hotplate soldering for koen.
  • [00:30:46] <emeb> the board for Beagle is just an FPGA & has no flash / SD on it. All FPGA bitstream comes from Beagle via SPI.
  • [00:30:55] <djlewis> that's what i get for passing names :(
  • [00:31:18] <emeb> :) np - just clarifying.
  • [00:31:40] * djlewis should have looked closer at picture earlier
  • [00:32:15] <emeb> that board has dsPIC on to read SD card & load FPGA. Works pretty well.
  • [00:33:14] <emeb> and to DanaG's point - yes, FPGA bitstream will have to be compiled on x86 machine. Tools are free tho...
  • [00:33:47] <DanaG> hmm, which "Free"? Last time I checked, the Xilinx tools were expensive.
  • [00:34:22] <emeb> Xilinx ISE Webpack is a free download & handles most parts in the Spartan3* family.
  • [00:34:33] <DanaG> ah... forgot that.
  • [00:34:36] <emeb> Definitely good for the part I'm using...
  • [00:34:53] <emeb> And runs on Linux too.
  • [00:35:12] <DanaG> Over the summer, I tried to get Linux booted on a Virtex-5 board... ouch. So many broken or nonexisting tools.
  • [00:35:44] <emeb> Running Linux on their Microblaze soft CPU sounds like asking for trouble.
  • [00:36:50] <DanaG> Yup.
  • [00:37:06] <DanaG> The .30 kernel added "support" for it... but yet there was no publicly available GCC to build it!
  • [00:37:26] <emeb> I haven't ever used the EDK or on-FPGA CPUs. Always have an external MCU running the show. Cheaper, better performance, better tools.
  • [00:37:51] <DanaG> Why pay $$$ and god-only-knows how many watts (came with a 120W brick) when you can get a beagle?
  • [00:37:53] <DanaG> =??
  • [00:38:08] <DanaG> Hmm, do you have any specific plans for what to do with the fpga attached to the beagle?
  • [00:39:56] <emeb> A few things: Interfacing to specific peripherals (Digilent has PMOD cards for SD socket, Ethernet, audio output, motor control, etc), thinking about co-processor apps, and finally Software Defined Radio (I've got some HF TX/RX cards in the works)
  • [00:40:19] <emeb> SDR is the main motivator though.
  • [00:40:24] <DanaG> Oh yeah, digilent now has an RF thingy, as well.
  • [00:40:47] <DanaG> In my embedded-systems class, some classmates made a crude AM radio using ONLY the ADC and DAC modules.
  • [00:40:57] <emeb> Yes - but it's got the full PHY on-chip so you don't get to muck with the waveforms.
  • [00:41:13] <emeb> Yep - AM radio is doable - sample rates are low enough.
  • [00:41:30] <ds2> emeb: what ADC?
  • [00:41:39] <emeb> With an FPGA though I can cover 80kHz - 20MHz.
  • [00:41:46] <DanaG> The class used the nexys2 + parallel lcd + DAC.
  • [00:41:51] <DanaG> I instead got S3E Starter Kit.
  • [00:42:20] <emeb> The RX card uses a TI analog frontend chip that samples @ 80MHz and then decimates/tunes/filters down to ~2.5MHz BW.
  • [00:43:01] <ds2> Nice... can it hear down to -150dBm?
  • [00:44:09] <djlewis> ds2, what? you wanna hear a gnat fart?

  • [00:56:11] <Ikarus> turns out SD only has a CS line when used in 1 bit mode

  • [00:57:24] <Ikarus> so if I want 4 bit mode I need to add a buffer chip with tristating
  • [00:59:59] <Ikarus> though in theory even 1 bit mode provides acceptable performance if I run the bus at 48Mhz (which iirc is supported)

  • [01:13:03] <emeb> nope - although that depends on your definition of instrument grade.
  • [01:13:21] <emeb> 12-bits @ 80MSPS is no great shakes these days.
  • [01:13:38] <emeb> OTOH, it will get the job done for proof-of-concept.
  • [01:13:50] <ds2> the toys the spectrum analyzers play with goes down to almost -200dBm
  • [01:13:54] <ds2> much much quieter
  • [01:14:07] <ds2> think they are limited by kT noise
  • [01:15:07] <emeb> Depends on how much you want to spend on the spectrum analyzer. I've got an Agilent E4402B here that does just fine, but costs ~$15k new.

  • [05:03:42] <sam1> hi
  • [05:05:24] <sam1> my I have just brought up- my beagle board. but it is not detecting my usb keyboard. what's the issue? keyboard is working fine with desktops and laptops.
  • [05:07:45] <av500> on which usb port?
  • [05:07:51] <av500> on the ehci you need a hub
  • [05:08:38] <sam1> av500, on ehci
  • [05:09:16] <sam1> i have also used with a usb hub with power suppy too.
  • [05:10:25] <sam1> but some how keyboard is not even getting power, like num lock or capslock key are showing (light)...

  • [05:21:12] <av500> sam1: and does the hub/mouse show up in dmesg output?
  • [05:22:07] <sam1> av500, after conneting to beagle board?
  • [05:22:28] <DanaG> You can't use both.
  • [05:22:34] <DanaG> They both try to claim /dev/watchdog
  • [05:22:38] <DanaG> not /dev/watchdogN
  • [05:23:08] <av500> sam1: of course

  • [09:01:43] <av500> apple? isnt that a closed thing?
  • [09:01:58] <topfs2> btw, we did a few tests on tegra yesterday and in a sandbox enviornment we got it close to 85fps. rather correct with the limitations xbmc has, so hopefully 30fps should be doable on tegra without the viewport limitation
  • [09:02:12] <topfs2> so BB with viewport limitation is hopefully able to make 30
  • [09:02:23] <av500> thats is video or UI fps?
  • [09:02:29] <topfs2> UI
  • [09:02:31] <av500> ah
  • [09:02:37] <topfs2> why video laggs I have no idea tbh
  • [09:02:55] <topfs2> very weird tbh since iirc cpu isn't stretched even
  • [09:03:02] <av500> you have the hw video drivers?
  • [09:03:17] <topfs2> you mean for gles? yeah
  • [09:03:21] <av500> no, for video
  • [09:03:41] <av500> and yes, cpu should be strechted for video as the thing lacks NEON
  • [09:04:11] <topfs2> Sure for anything real, but it lags on SD even without cpu maxing out IIRC
  • [09:04:22] <av500> k
  • [09:04:44] <topfs2> not sure why, its really wierd
  • [09:05:12] <topfs2> although, the shaders involved with video does quite abit
  • [09:06:02] <av500> ah right, you render all pixel via GL
  • [09:06:57] <topfs2> yeah, would be interesting disableing that and see how much that would do

  • [09:13:38] <jumoit> av500: yeah, i see. i mean how i should deal with it in kernel?
  • [09:13:49] <av500> not at all
  • [09:14:01] <av500> you need a driver for that modem of course
  • [09:14:11] <av500> but that is the same as on std linux
  • [09:14:29] <av500> to hook it to android, you need to port/adapt a rild for that modem
  • [09:14:35] <av500> that is the tricky bit
  • [09:14:40] <nlCortana> hi, im trying to open a quickcam messenger. Therefore I have installed kernel-module-quickcam-messenger and libv4l using opkg. But it still doesn show up in the device list neither in lsmod

  • [09:18:40] <av500> jumoit: yes, you could pay me or try google for free :)

  • [14:52:07] <jkridner> my guess is that the issue might be some changes in the rest of your system. anyway, the code shouldn't have null pointer issues, so it is hard to claim that isn't an issue--even if you are doing something else odd in the system (unless you are poking some internals).
  • [14:54:54] <dl9pf> ok, i'll try these. system is normal rootfs@armv5, compiled with gcc4.4, so nothing special

  • [23:27:00] <emeb> ds2: that's true, but once the FPGA has a key stored in it, it will only load bitstreams that are encrypted with that key. So the attacker can't put arbitrary stuff in the part to help discover the key. They have to rely on power analysis during the normal configuration process, which means instrumenting the target board out the wazoo and then hitting 'reset' over & over and hoping they can collect enough data.
  • [23:28:55] <ds2> emeb: I was thinking more along the line of decap'ing it and looking at it with a STM or like
  • [23:30:13] <emeb> ds2: could work. Altera stores their keys in NV memory on-chip. Xilinx stores it in battery backed SRAM. Difficult to decap & STM without letting the SRAM bias drop though.
  • [23:30:56] <ds2> emeb: are these the metal packaged BGAs or the plastic ones? plastic might not be that hard to do
  • [23:33:06] <emeb> ds2: depends - key protection is only available on the high-end parts and those come in both thermally-enhance (metal) and plastic BGAs. Most are flip-chip though, so you'd have to go in from the bottom to scan the active region, which means digging in through the board & leadframe. Try doing that while keeping the backup supply going. :)
  • [23:34:45] <ds2> emeb: I think you can use temperature to help a bit there... I seem to recall something about chilling things to extend the time before ram degrades
  • [23:34:52] <Crofton|work> I'm sure glad I do not need to worry about these things :)
  • [23:35:07] <emeb> Crofton|work: ditto.
  • [23:35:18] <ds2> theory says contents disappear the moment power vanishes but in reality, I think think that is the case
  • [23:35:45] <emeb> ds2: I've seen that - a can of freeze-spray on the SDRAMs allows you to pull them out and grab the contents in another machine.
  • [23:36:17] <emeb> I think folks were extracting software keys & other data from laptops that way.
  • [23:36:26] <ds2> prehaps combine that with the coldness to make the case brittle enough to crack it open for decapping

  • [23:49:20] <ds2> a Farnell cross referenced order is faster then a ground shipping order from Newark assuming custom cooperates
  • [23:49:33] <ds2> the flat $20 shipping apparently is for air
  • [23:50:28] <emeb> or maybe I'm confusing them with Futurelec. One of those European 'F' companies that often claims to have things in stock, but backorders 2mo after you place the order.
