**** BEGIN LOGGING AT Thu Oct 29 02:59:57 2020 Oct 29 10:34:26 * veremitz drive-by eyerolls, wanders off again Oct 29 11:56:46 hi, somebody uses this procedure https://elinux.org/BeagleBone_Black_Extracting_eMMC_contents ? Oct 29 11:58:03 I've been using if for years but I find that last BBB I bouhgt, it does not work any more (not backup creation, not backup restore) ! Oct 29 12:35:01 Hello? is this live? can anybody read me? Oct 29 12:47:04 Test successful? lol Generally if one has a question, they simply put it out there. If someone has the time and is able to respond, they will. Oct 29 12:49:24 don't forget, if they _want_ to respond Oct 29 12:50:16 Well if they don't want then they may not be "able", either. (wink) Oct 29 12:56:17 ok, thanks Oct 29 13:54:27 Heh! Oct 29 13:54:35 replies are the bees knees. Oct 29 13:54:56 I am attempting to put GRBL on the BBB. Wish me luck? Oct 29 13:55:14 I am making this drawing bot whether I like it or not... Oct 29 14:00:42 Now, if someone could only teach me about PRUs. Ooh? Oct 29 14:05:24 faustogut: I saw your post on google groups. Oct 29 14:05:54 I read it. I have not tried that script in some time now. Maybe another person has tried recently. Oct 29 14:15:42 PRUs aren't hard; took me under a week to get going, but my knowledge is all five years old. Other means are avialable that I don't know. Oct 29 14:19:10 I have been reviewing details for the PRUs when I have time for the am335x. Oct 29 14:19:39 I am a very slow learner, i.e. b/c of projects that i like to make work and have accessible. Oct 29 14:19:51 You know it is not easy being a person in the digital age. Ha. Oct 29 14:20:25 Afiac the first thing you have to decide is C or asm. How you go about it derives from that. I used C b/c my requirements are not stringent. Oct 29 14:20:45 set_: I'll wait for anybody with news about it. Thanks Oct 29 14:24:13 Ragnorok: Yep. I know about C more than assembly. So, I will most likely get into it w/ what little knowledge I have on the c language. I have some older, tested scripts for PRUs on the am335x but I never got past them. Oct 29 14:24:30 faustogut: Yea boy! Oct 29 14:26:11 Next would be your environment. I use Code Composer b/c I'm familiar with Eclipse, so it was simple for me to set it up. If you use CCS, TI has an install for PRU that does most of the work. Oct 29 14:28:43 I would expect using make would be like anything else; install the compiler then spend hours of monkey work wading through crappy make file building. But once it's all done it'll build until the end of the universe. lol Other make options exist as well but I hate make so much I've been unable to investigate them. (shrug) Oct 29 14:28:46 Right. I am familiar w/ it. Oct 29 14:28:54 Ha. Oct 29 14:29:15 yea. clpru has a cli. Oct 29 14:29:23 So, I just use it from the command line., Oct 29 14:29:37 Sounds like you're well on your way then. Oct 29 14:29:58 Or at least when I was trying more often, that is how I used to try to use the scripts. Oct 29 14:30:13 I found that you are right about Makefile. Oct 29 14:30:32 It is hard to get all the quirks out but when it is done, it is completed. Oct 29 15:30:52 it looks like GRBL is only for the avr family of computerers. No! Oct 29 15:30:57 I wasted more time. Oct 29 15:31:24 Oh. well, off to dwell in misery. Limps and back issues abound! Oct 29 15:32:30 Porting sounds like a great way to learn PRU. (grin) Oct 29 15:34:08 Either that use the B'Bone to talk to a Pro Mini running GRBL. (shrug) Oct 29 15:35:49 Ha. Oct 29 15:35:57 Double ha. Oct 29 15:36:06 Anyway, off to garble my misery! Oct 29 15:39:21 or you know lookup the machinekit project Oct 29 15:40:08 I've done the linuxcnc on it before, kinda painful to setup the configs just right, but it works fantastically. Oct 29 20:01:43 any simplish divide mechanisms in the pru? Oct 29 20:01:57 by variable i mean. Oct 29 20:15:52 >> lol Oct 29 20:17:41 I used C to code mine and that seems to implement something for me. Oct 29 20:20:34 yea, I'm thinking i probably need to implement it in assembly. seems like i only need to divide by a variable once to get position between 2 points to implement a spline-fit i am trying to write. Oct 29 21:00:05 Woot! just realized it doesn't need to be computed on the fly, I can just add another lookup table for the 1/x's and use a multiply instead,Woot! Oct 29 22:41:05 juding by no response looks like if the PRU triggers a segmentation fault it cannot recover after it Oct 29 23:43:39 I guess I will have to get MachineKit. Oct 30 00:10:49 I guess not or maybe so? Oct 30 00:11:30 I just went to the machinekit image thingy for the BBB. It seems they are compelled to keep the 3.8 kernel alive w/ Wheezy or before that even? I have no clue really. Oct 30 00:12:06 I have never seen this page but it exists. I remember when their people used to make already compiled images. Oct 30 00:12:07 Hmm. Oct 30 00:12:16 Oh well. Oct 30 00:12:18 Yikes. Oct 30 00:12:50 I am warped. Let me start clicking links again. Oct 30 00:19:22 ooh. Oct 30 00:19:24 Nice. Oct 30 00:21:29 For some reason...I figured those images were halted. Nope. Not halted. Not stopped. They exist! Oct 30 00:40:50 Hey. Oct 30 00:41:32 "ooh. Nice." was said and I mean it. Thank you to whomever built it, put it together, and it strapping enough to keep it ongoing. Boy! Oct 30 01:08:29 Oh. Oct 30 01:08:48 You guys did it. I keep on forgetting. Oct 30 01:09:58 I should direct my "quarrels" to MachineKit at google groups. up, up, and Otay! Oct 30 01:12:13 you argued with yourself and lost? Oct 30 01:14:59 Again... Oct 30 01:15:17 I usually do this and do it well, I may say. Oct 30 01:15:52 Machinekit w/ a ./grow_partition.sh script hates Win 10. I moved to Linux. Oct 30 01:16:01 It booted! Oct 30 01:17:03 boot to the head? Oct 30 01:17:19 Nope. Scratch that...no boot. Oct 30 01:17:42 I knew I should have took the option to upgrade instead. Dang it. Oct 30 01:27:46 Hey guys, you guys? Oct 30 01:28:11 The image is corrupted. It will not allow me to write it on Linux Ubuntu Distro, mane. Oct 30 01:28:38 I know they say debian but is ubuntu just a flavo"u"r of debian? Oct 30 01:29:49 constinance and consellation. I need it, mane. Give me! Oct 30 01:45:14 Forget it. I will try to wait longer. **** ENDING LOGGING AT Fri Oct 30 02:59:57 2020
