**** BEGIN LOGGING AT Sun Nov 23 03:00:00 2014 Nov 23 10:09:22 Hello :) Nov 23 10:11:26 i have a problem for loading Tigal Mikrobus Cape firmware Nov 23 10:11:49 bone-capemgr bone_capemgr.9: failed to load firmware 'BB-MIKROBUS-01-00A1.dtbo' Nov 23 10:12:15 but this file (and the .dts) are in /lib/firmware Nov 23 10:15:19 <_av500_> asked tigal? Nov 23 10:16:22 _av500_, Tigal have an IRC chat ? :) Nov 23 10:17:27 (and my internet connection is very bad... :( ) Nov 23 10:20:52 the firmware is from Tigal GitHub Nov 23 10:31:56 (hte download.tigal.com is not known Nov 23 10:31:58 ) Nov 23 11:24:34 guys i need your healp with my bbb Nov 23 11:26:03 i've download ubuntu image on my SD card but since that my bbb can't boot anymore Nov 23 11:26:04 http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ Nov 23 11:26:41 i only have USR0 led that blink Nov 23 11:40:20 eth0 problems help. I have failed to find anything helpful on google.. :( Nov 23 11:46:27 jgladen: if you expect help, be much more specific Nov 23 12:23:33 anyone use the Tigal Mikrobus Cape on Debian ? Nov 23 13:19:35 hi! Nov 23 13:20:09 how can i save the uboot env on my bbb? i get: Nov 23 13:20:11 U-Boot# saveenv Nov 23 13:20:11 Saving Environment to NAND... Nov 23 13:20:11 Erasing Nand... Nov 23 13:20:13 Attempt to erase non block-aligned data Nov 23 13:20:21 this cannot work as the bbb has no nand :) Nov 23 13:20:25 how to tell uboot? Nov 23 13:21:20 derRichard, hi, you're on Angstrom ? Nov 23 13:21:33 Kos-teK: yes. some image from 2013 Nov 23 13:21:43 (the internal mmc image) Nov 23 13:21:50 i'm not using an external sdcard Nov 23 13:22:10 derRichard, oh, sorry, i use Debian and i don't use Angstrom... i can't help you Nov 23 13:22:50 but i'm talking about u-boot. was u-boot also changed? Nov 23 13:24:10 my uEnv, in debian is in /boot/uboot/uEnv.txt Nov 23 13:24:27 and you not need to saveenv Nov 23 13:25:29 but if i want to use saveenv? does it work for you? Nov 23 13:25:46 IOW is saveenv just broken on the bbb? Nov 23 13:26:49 i don't have this command in Debian Nov 23 13:28:01 again, saveenv is a *u-boot* command Nov 23 13:28:04 not a linux shell command Nov 23 13:28:10 *an Nov 23 13:29:07 oh sorry, i don't user it... Nov 23 13:29:14 (i'm a newbie on BBB) Nov 23 13:29:16 ... Nov 23 13:29:42 but, the bbb have an eMMC Nov 23 13:30:01 sorry. you've no idea what i'm talking about Nov 23 13:30:01 so it have a NAND storage Nov 23 13:30:18 ah ok Nov 23 13:30:19 ...but no raw nand Nov 23 13:31:34 btw: i find on http://beagleboard.org/latest-images only flasher images. why are there no images for an external mmc card? i don't want to overwrite the internal mmc Nov 23 13:31:55 never mind Nov 23 13:32:01 * derRichard needs to read better :-\ Nov 23 13:42:57 derRichard: maybe ask on an u-boot channel, they might know? as you noticed, not that many u-boot experienced people around here. (I haven't used saveenv since the BB classic...) Nov 23 13:46:34 tbr: the problem is not u-boot specific. it is specific to the bbb. Nov 23 13:46:59 derRichard: I am well aware of that. Still someone there might know. Nov 23 13:48:49 tbr: i assumed that bbb guys hang around here and not on the uboot channel ;) Nov 23 13:52:14 <_av500_> derRichard: I dont think the BBB uboot supports savenv Nov 23 13:52:41 <_av500_> Tartarus: ^^^ Nov 23 13:54:07 _av500_: okay Nov 23 13:55:41 btw: currently i work from an external sdcard where the most current debian image is installed. if i add a new variable to /boot/uboot/uEnv.txt uboot still does not know it. Nov 23 13:55:52 how is the uEnv.txt magic supposed to work? Nov 23 13:59:55 <_av500_> derRichard: the issue with uEnv.txt is that it is only being read from the "boot" command in uboot Nov 23 14:00:15 <_av500_> so if you interrupt uboot by pressing a key, it has not been read Nov 23 14:00:43 <_av500_> there are uboot patches for a preEnv.txt thats is read first thing Nov 23 14:00:57 <_av500_> which makes it behave more like an env in nand Nov 23 14:01:01 <_av500_> or the old boot.scr Nov 23 14:01:16 hmm, that's not good. because u-boot evaluates the ethaddr variable before bootcmd is executed Nov 23 14:01:36 preEnv.txt sounds good. /me reads on that Nov 23 14:03:52 i better upgrade to a recent mainline kernel where the ethernet driver has ndo_set_mac_address implemented Nov 23 14:04:05 such that i can change the mac in a sane way in user space Nov 23 14:20:01 <_av500_> derRichard: http://pastebin.com/urQ3FPt1 Nov 23 15:10:45 _av500_: thx Nov 23 15:54:44 hi yates Nov 23 15:55:17 yes, you can run the ARM in standby while running the PRU, but you can't do the lowest chip power modes. Nov 23 15:55:48 you can drop the CPU voltage, gate the clock and get it pretty low.... even go into memory retention. Nov 23 20:04:42 is /etc/network/interfaces not respected on beagleboard black debian? Nov 23 20:08:37 moin. Nov 23 20:08:50 What are the current requirements to run beaglebone black ? Nov 23 20:09:22 power, and a bbb .. ? Nov 23 20:09:32 oh Current .. XD Nov 23 20:09:42 yes as in amperage Nov 23 20:09:52 2A+ if you're using peripherals :) Nov 23 20:10:24 I have a 9v batter powering the bbb through a 5v regulator and the bbb just shuts off. It's leds go out as if it can't finish booting. Nov 23 20:10:36 yes, I'm hardly surprised. Nov 23 20:11:11 you'll want a beefy regulator (probably switching) to get the startup current and keep it for booting Nov 23 20:11:15 did i detach right when someone answered about etc/network/interfaces? :P Nov 23 20:11:55 <_av500_> 9v batteries dont deliver enough current Nov 23 20:12:16 the regulator most likely shuts down .. especially if your battery voltage dips near to the 7v where it'll run out of juice Nov 23 20:12:43 unless you have one of those PP9 ones .. Nov 23 20:12:46 that should work Nov 23 20:13:33 http://www.amazon.com/Eveready-EB1030-EVEREADY-9V-PP9/dp/B000LMQ3SK/ref=cm_cr_pr_product_top Nov 23 20:14:54 or you can go lead-acid .. http://www.amazon.com/Rechargeable-Sealed-Lead-Battery-Electronics/dp/B000BPCUXO .. but those are the Smallest batteries that are practical (save LiPo/Li-Ion) for embedded computers Nov 23 20:19:16 blah44_: no one responded to that yet Nov 23 20:19:42 _av500_: I've run off of a 9V for hours if the regulator is good. Nov 23 20:19:54 I use the Andice power bar. Nov 23 20:20:14 Not fancy 9V either. Nov 23 20:20:38 Using USB cell phone chargers is generally better. Nov 23 20:20:57 <_av500_> jkridner: ok Nov 23 20:21:21 nurple: using an LDO, however, usually doesn't work. There are a handful of LDOs that do provide enough current, but they don't generally provide a good experience. Nov 23 20:22:11 nurple, _av500_: you can check out an LDO that *mostly* works at http://o-botics.org, but you have to have a fresh/high-quality 9V battery. Nov 23 20:22:14 thats a natty lil thing Nov 23 20:22:52 LDO will mean you need to have a lot of extra power. Nov 23 20:23:15 * jkridner hates using linear regulators (LDO or otherwise) with BeagleBone Black. Nov 23 20:24:09 So-called ABECs work OK. I picked up a couple from Adafruit. Nov 23 20:24:15 I much prefer the Andice power bar. Nov 23 20:24:32 LDO ? Nov 23 20:24:40 low drop-out... Nov 23 20:24:48 a type of linear regulator. Nov 23 20:24:51 ok Nov 23 20:25:04 http://en.wikipedia.org/wiki/Low-dropout_regulator Nov 23 20:25:18 basically just a diode. Nov 23 20:26:03 well, I guess an older-style linear regulator would be just a diode. Nov 23 20:26:13 with quite a few extra transistors, jkridner Nov 23 20:26:13 an LDO is a minor improvement. Nov 23 20:26:22 switching regulators are the way to go. Nov 23 20:26:35 much more complicated to the novice though Nov 23 20:26:52 yeah, but switching solutions exist off-the-shelf. Nov 23 20:27:04 whereas a 7805 is very standard and only has 3 legs :p Nov 23 20:27:12 http://andicelabs.com/beaglebone-powerbar/ Nov 23 20:27:14 so I see Nov 23 20:27:15 <_av500_> and burns half the power of the 9V Nov 23 20:27:25 bet thats more than 70c too ;p Nov 23 20:27:44 oh we're not talking about efficiency here .. thats a totally new argument .. Nov 23 20:28:58 <_av500_> http://www.aliexpress.com/item/Free-Shipping-10pcs-LM2596-LM2596S-ADJ-DC-DC-4-5-40V-adjustable-step-down-power-Supply/1079777060.html Nov 23 20:29:03 <_av500_> jkridner: I got a bunch of these Nov 23 20:29:22 2596 works well .. actually most national switchers do Nov 23 20:29:49 <_av500_> not arguing with 50ยข :) Nov 23 20:30:00 na .. chip costs more than that Nov 23 20:30:45 aight .. bbiaf .. need provisions Nov 23 20:33:03 hmm Nov 23 20:33:16 it appears my network problem is specific to usb0 Nov 23 20:33:51 i have no physical usb networking, commented it out of etc/network/interfaces, where the heck is it getting this IP!? Nov 23 20:38:18 ah geez looks like it might be coming from the boot FAT filesystem Nov 23 20:38:23 no wonder i could not find it before Nov 23 20:49:06 blah44: It comes from an init script... Nov 23 20:49:12 blah44: I'm trying to remember the location. Nov 23 20:51:53 oh yes, /opt/scripts/boot/am335x_evm.sh Nov 23 20:51:57 oh well blah44. Nov 23 20:55:43 usb networking has nothing to do with Real networking :) Nov 23 22:13:46 anybody has issues with GTK on the latest angstrom build? **** ENDING LOGGING AT Mon Nov 24 03:00:31 2014
