Nov 03 07:00:07 something is wrong but can't tell you anything specific w/o more info Nov 03 07:00:42 and i m not able to connect my bbb to see ifconfig Nov 03 07:01:00 okay Nov 03 07:01:11 then.. something is assigning a bad address Nov 03 07:01:25 can you ping 192.168.1.2? Nov 03 07:07:01 no Nov 03 07:08:03 how do you manage network connections on your laptop? Nov 03 07:14:38 now its not showing port 22 connection refused ..but its going to hange i was trying to login in to bbb through usb Nov 03 07:15:40 i am not able to see login session in my pc to bbb Nov 03 07:26:31 no Nov 03 07:32:56 hi Nov 03 11:14:38 sorry if i am in the wrong place I need to know if there is a way of controlling dc motors 12 volt dc @20 amps is there a way to do it thanks guest37919 thanks Nov 03 11:15:56 I'm sure there are ways Nov 03 11:16:14 the simplest is a relay Nov 03 11:16:57 that would be interesting to see in action Nov 03 11:17:12 *brzzzzp* Nov 03 11:17:52 and yes, a dedicated motor controller should be the way to go Nov 03 11:18:26 adj: now that I think of it, I wonder if a) the initial current or b) the torque would make things go spectacular Nov 03 11:19:47 I'm sure there is this thing called literature on the topic of controlling DC motors Nov 03 11:20:15 I have built large radio controlled boat & plan on using mine kota electric outboard, would like eventually fully autonomous Nov 03 11:20:26 i was thinking more of the torque Nov 03 11:21:28 i have seen how bad idea it is to give an atmel controlled RC car chassis to students Nov 03 11:22:14 initially the power control was always "all or nothing" Nov 03 11:22:42 some of that might fall into "you try, I watch" territory Nov 03 11:25:28 there was a guy controlling large dc motors with atmega 328 I think,& arduino but i have lost the link sorry I am very new to all of this Nov 03 11:27:53 thanks for your help will keep looking thanks again. Nov 03 11:28:15 you could also look at those CNC capes etc Nov 03 11:28:24 they also control motors, but those are steppers Nov 03 11:28:38 best thing is to get into the basic theory though Nov 03 11:34:47 yep your spot on with the theory thing, am recovering from an operation & trying to teach myself a few things like learning ROS etc while off work my only real related experience is with rc models mostly multi rotors & boats ,don,t want to waste anybodys time so thanks again. Nov 03 12:48:16 why i can not drive a brushless motor with L293D IC :( ? **** BEGIN LOGGING AT Tue Nov 03 14:50:40 2015 **** BEGIN LOGGING AT Tue Nov 03 17:27:42 2015 Nov 03 21:41:56 On my Beaglebone Black, I could edit uEnv.txt to change the config; on the Green there is no such file on the vfat partition, and putting it there doesn't seem to do anything. There is one in /boot, but that doesn't seem to be used either. How can I change the settings (in particular, disable the kernel console on /dev/ttyO0)? Nov 03 21:46:24 shevek, "mmcargs"... printenv the current version and remove the console parameter.. Nov 03 21:47:27 rcn-ee: I'll look at that, thanks! Nov 03 21:53:45 rcn-ee: mmcargs is not a command and I can't seem to find a file by that name either? Nov 03 21:57:07 Hi Nov 03 22:02:32 shevek, it's a variable.. that's run before "bootargs".. Nov 03 22:06:16 rcn-ee: I don't follow what you're saying. Which file should I be editing? Nov 03 22:07:19 shevek, "mmcargs" is a variable in u-boot, stop at u-boot prompt type "printenv" look at mmcargs set your own in /boot/uEnv.txt without the console variable... Nov 03 22:08:28 Ah, ok. I don't have access to the uboot prompt at the moment. But I can get the commandline from /proc/cmdline, and I tried putting that (minus the console= part) in /boot/uEnv.txt and it didn't seem to have any effect. Nov 03 22:09:51 But I wouldn't expect it to either; /boot is on the ext4 system, can uboot read that? Nov 03 22:16:31 wrong uEnv I should imagine ;P Nov 03 22:16:46 and, uhm, Get A Serial Cable :) Nov 03 22:21:20 i downloaded the sd card Deabian image from beagleboard.org, attached it to an bbb A5A, but something looks wrong with the boot process, i allwayes end up in CCCC meaning it tryes to boot from serial, missing to boot from sd, i checked with u-boot conslole, all files on the card are readable so it is not the sdcard, is it possible that there is a incompatible version of u-boot on my beaglebone black, i have to state that i miss the MLO Nov 03 22:21:20 and u-boot.img on the fat partition of the debian.img.xz from the latest images page Nov 03 22:22:15 probably need to press the boot button to get it to load u-boot off of the sd card Nov 03 22:22:25 if your SD card has u-boot installed Nov 03 22:27:21 my sd card has not uboot installed Nov 03 22:27:45 Debian (BeagleBone, BeagleBone Black - 4GB SD) 2015-03-01 - more info - bittorrent - md5: c848627722b7a5f7bc89791cc8949e3b Nov 03 22:27:50 it is that image Nov 03 22:27:57 from Nov 03 22:28:03 http://beagleboard.org/latest-images Nov 03 22:28:11 i would have expected them to boot Nov 03 22:28:40 tat: something corrupted u-boot on the eMMC, so you need to load it from somewhere else. Nov 03 22:29:15 i can boot from eMMC straight, i have an Angstrom on there, Nov 03 22:29:32 could the u-boot still be corrupted ? Nov 03 22:29:50 i mean it buts the OS from on the eMMC Nov 03 22:29:56 s/buts/boots Nov 03 22:30:30 probably an old version of u-boot not configured to boot off of SD Nov 03 22:31:42 or the u-boot is expecting to see the MLO on the SD card's fat partition ... but i think we've switched to writing directly to the raw device rather than file-based. Nov 03 22:31:44 where are current u-boot images located for the bbb Nov 03 22:32:03 tat they are dd'ed to the MBR Nov 03 22:32:33 you mean i have to get them out with hexdump and the right offset Nov 03 22:32:50 or dd... Nov 03 22:32:57 tat: just grab the latest: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2015-11-03 Nov 03 22:33:12 issues in 2015-03-01 Nov 03 22:33:14 if i have to rite a new u-boot to the nand, i would need that fiel on an fat or ext partition to write to nand Nov 03 22:33:26 rcn-ee: thanks, Nov 03 22:33:59 tat the dd parameters are listed here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard Nov 03 22:37:00 rcn-ee: so if i use a flasher image does it update the u-boot on the eMMC too Nov 03 22:37:19 there isn't an mlo these days .. is there? Nov 03 22:37:27 uboot isn't dd'd anywhere .. *ick* Nov 03 22:37:37 tat yes.. the flasher updates everything on the eMMC... make sure use use the "2gb" image as you have an old board.. Nov 03 22:37:39 its a file on a partition. Nov 03 22:37:44 yep Nov 03 22:37:49 thanks Nov 03 22:38:02 veremit, anything after "dm81xx" bootrom, doesn't need the vfat partiion with mlo/u-boot.img Nov 03 22:38:30 and what a relief, not needed a partition for the mlo/u-boot.img Nov 03 22:38:51 rcn-ee..phew. Nov 03 22:39:00 vagrantc, did you see config_distro is now in mainline u-boto for am335x ;) Nov 03 22:54:23 rcn-ee: no, i didn't! Nov 03 22:56:02 rcn .. did you see the B-Pi-M2 ? it's lost the sata though :( Nov 03 22:56:38 veremit, need to find a power connector for that board. ;) Nov 03 22:56:53 you ain't got a dc barrel about!??! Nov 03 22:57:00 rcn-ee: just acked, or actually in mainline? Nov 03 22:57:26 vagrantc, http://git.denx.de/?p=u-boot.git;a=commit;h=bc3199fd1875f89e9e1fb2af45665c4a718217b9 Nov 03 22:57:37 veremit, not that size. ;) Nov 03 22:57:50 ah they put a teeny one on .. go them. Nov 03 22:58:54 rcn .. I'll reserve judgement until you've powered yours then :) not 100% on that wifi .. Nov 04 00:30:44 hmmm rpmsg definitely has some annoying features Nov 04 02:31:03 hi Nov 04 02:31:48 * billy_ slaps zmatt around a bit with a large fishbot Nov 04 02:32:37 I hope that does leave fishguts Nov 04 02:33:25 * veremit orders a shark to 'clear up' ... Nov 04 02:35:38 this could be a bit messy ... **** ENDING LOGGING AT Wed Nov 04 02:59:58 2015
