**** BEGIN LOGGING AT Sun Jun 01 02:59:58 2014 Jun 01 04:36:25 Hi Jun 01 04:36:36 hi Jun 01 04:37:01 I just needed some info on a project in beagle board black Jun 01 04:37:32 what u need boy Jun 01 04:38:45 I am the director of a startup firm in India. We are planning to make a product with in 1 year Jun 01 04:39:08 I just wanted to know if beaglebone gives support for the chip and its drivers Jun 01 04:39:27 its al open source Jun 01 04:40:29 Kutto, are you plannign to use spin your own board, or use the BBB and interface onto it Jun 01 04:40:31 Do they built the body of the product if we say the requirement Jun 01 04:41:09 I wanna use BBB and do custm interface on top of it Jun 01 04:41:29 the way things are right now, you'll really struggle to get any support for that Jun 01 04:41:57 they are not supplying people who want to build products with it. Jun 01 04:42:25 I dont need people Jun 01 04:43:30 your best to spin your own board Jun 01 04:43:30 all the files are open though Jun 01 04:43:30 ? Jun 01 04:43:30 you'll just struggle to be able to buy enough beaglebones to put into your products Jun 01 04:45:11 they never want to listen. Jun 01 04:54:56 whats the bet Kutto 's startup will hit a dead end? Jun 01 05:02:31 1000 rupees? Jun 01 06:42:41 I've erased the u-boot.img on my BBB's eMMC. I'm trying to boot the board from an SD card, but I still get the same message: `spl: error reading image u-boot.img, err - -1`. I have copied the MLO and the u-boot.img files onto the SD card formatted with this: http://www.crashcourse.ca/wiki/index.php/Formatting_SD_card_for_the_BBB script. Holding the boot button doesn't help either. Please help. Jun 01 06:44:35 Do you remove power fully before attempting to boot to the SD? Jun 01 06:45:51 foreverska: Yeah, and I'm powering it through USB, if that helps. Jun 01 06:48:04 try a ready made image first Jun 01 06:49:21 tbr: do you mean just unpack an image from http://downloads.angstrom-distribution.org/demo/beaglebone/ to the sdcard? Jun 01 06:51:12 I'd specifically use an image, not a tarball Jun 01 06:51:17 so first one on the top Jun 01 06:51:33 that rules out most copy errors Jun 01 06:51:49 make sure to write it to the raw device and NOT a partition Jun 01 06:52:29 tbr: okay. trying it out. Jun 01 08:35:46 tbr: Hey! The readymade image worked! I wonder what's wrong with me partitioning the card manually and copying MLO and u-boot. It simply gets stuck at u-boot not found Jun 01 09:03:01 varad: It might be the case that the MLO and u-boot are aligned to the beginning of the SD card, while your copying the file there doesn't guarantee the alignment Jun 01 09:04:26 Abhishek_: hmm... do you know how I could ensure that they are copied with proper alignment? Jun 01 09:05:10 I do not know yet, maybe someone else could tell you more Jun 01 09:25:09 varad: usually what I hear (and I'm not sure if I've tested this) is to first format the boot partition, then explicitly copy the just MLO file first--then whatever else afterwards, e.g. a u-boot image or a uEnv.txt Jun 01 09:25:48 it's very important that the MLO is the first file logically on the device Jun 01 09:28:43 jpfau: I am copying the MLO just after formatting the card, right before I copy anything else. Jun 01 09:29:29 is that not working? Jun 01 09:29:57 actually, you said it can't find the u-boot image, which means it's at least bootstrapping the MLO, I think Jun 01 09:30:20 I haven't done much debugging of the boot process unfortunately Jun 01 09:30:38 my board has been off for far too long at this point until I get around to debugging the boot sequence Jun 01 09:32:52 jpfau: I "accidentally" deleted the uboot image from the eMMC. It still has the MLO it shipped with on it. Jun 01 09:33:07 aha Jun 01 09:36:12 varad_: You could get u-boot.img from a stock image, and tru Jun 01 09:36:14 *tyr Jun 01 09:36:16 *try Jun 01 09:38:18 I just tried manually partitioning the card with gparted and copying the files. Didn't work :( Jun 01 09:57:31 It worked! I dd'ed /dev/zero to the MMC and tried the whole process again. Phew! Jun 01 14:53:02 hi Jun 01 14:54:15 what is psplash ? I am trying to make a image splash appear early in the boot process on my BB Black ... Jun 01 14:54:36 Does anyone have an idea .. how to make it work Jun 01 14:54:39 thanx Jun 01 14:57:01 where have all the experts gone ? Jun 01 14:58:43 used to be you just installed the psplash package and altered the kernel command in uEnv.txt to get it to show Jun 01 14:59:51 don't recall if it was splash=true or psplash=true that you had to add Jun 01 15:00:49 hmm ok Jun 01 15:01:54 actually i want to display the screen soon after boot so was thinking of adding support in u-boot assuming its possible Jun 01 16:05:14 c Jun 01 16:38:15 hallo. I have a question about the debain on the new beagle bone black. Jun 01 16:39:06 I got a loop between service rmnologin and mountnfs Jun 01 16:40:21 does some one have a idea? Jun 01 16:50:55 Help, I tried plugging in my BBB today and nothing happened. No power led, nothing. Did I kill it? Tried using usb power and AC/DC converter from adafruit Jun 01 16:58:56 awyea: what rating does the power supply have that you plugged it in? Jun 01 16:59:33 How can I look into the kernel I built and see copy_from_user came from which source, was the default implementation used or an assembler version. I'm currently doing readelf -s vmlinux | grep copy_to_user, is there a better way? thanks. Jun 01 17:00:01 2amp Jun 01 17:00:21 checked voltage, 5.14v Jun 01 17:00:55 awyea: are you usually booting from SD-card or from eMMC? Jun 01 17:01:14 sd card, tried it without too Jun 01 17:02:01 and none of the LEDs light up? Jun 01 17:02:14 yes, none Jun 01 17:03:15 last thing to try: write a fresh, known working image to an SD card and try to boot that Jun 01 17:03:43 I don't remember, but the SRM probably also tells you about test points and the voltages you should see there Jun 01 17:42:16 I have a quick question about device trees: All I am interested in doing is using the peripherals on the BBB. ie) interact with GPIO, ADCs, etc... Do I need to work with device trees to do this? Jun 01 17:42:33 I am finding so many tutorials about them, but I don't see why it is necessary to work with them Jun 01 17:48:40 The only reason you need to modify the device tree is if you want pins that are normally taken by something else (HDMI, eMMC, status lights, etc) Jun 01 17:54:32 Ah I see. And that is where device tree overlays come in? Jun 01 17:57:04 Well yea, device trees help identify who has what to the system. If you load the UART overlay for example you shouldn't be able to perform GPIO operations on it anymore. Jun 01 17:58:14 my confusion is whether I need to write my own device trees or not. the tutorials I'm seeing seem to imply that I do Jun 01 17:58:20 but it doesn't make sense to me Jun 01 17:58:36 there should be device trees setup that you can use for whatever configuration you need Jun 01 17:59:09 Just for GPIO or ADC? nah. Jun 01 17:59:39 In what situation would one actually need to write device trees? Jun 01 18:00:26 If you made your own cape... or if you were packaging a service for other people to use and wanted to protect them from using the pins it used. Jun 01 18:01:37 okay i see. This is what I had assumed, but it seemed unclear from what I had read Jun 01 18:01:38 thanks Jun 01 19:12:20 how do I load /dev/spidev1.0 on debian? Jun 01 20:27:17 hi guys i need some help. I compiled a kernel for the beagle bone black and made sure it had argus cape support. i however do not have the bone_capemgr under sys/devices what did i miss Jun 01 21:57:07 Lets say I LBCO R11, C24, 0, 1. It's going to fill the rest with zeros right? Jun 01 23:02:24 Lets say I LBCO R11, C24, 0, 1. It's going to fill the rest with zeros right? Jun 01 23:20:56 wish I could help you foreverska but I don't know Jun 02 02:21:05 Lets say I LBCO R11, C24, 0, 1. It's going to fill the rest with zeros right? Jun 02 02:33:09 hola a todos soy nuevo Jun 02 02:51:56 sorry guest I don't speak spanish, but welcome, anyway **** ENDING LOGGING AT Mon Jun 02 02:59:59 2014
