**** BEGIN LOGGING AT Tue Mar 29 02:59:57 2022 Mar 29 04:52:17 I know it is too late to replay or relay here but BOO YA! Mar 29 04:52:34 BBBlue and rt on the Bullseye. You guys rule! Mar 29 04:57:37 Anyway...I always thought this project should have been in the records and updated to current times "CONSTANTLY." I am sorry for posting so late but this when I BBBlue w/ ArduCopter. Mar 29 05:46:23 Hey, does anyone know where I could find survival temperatures for the BeagleBone Black? i.e maximum and minimum temperature before the board would likely be damaged while turned off. storage temps work too Mar 29 05:51:18 SRM Mar 29 05:54:08 DeusVoltage: Here... https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual Mar 29 05:54:23 It is long. I will check to see if I can find it quickly. Mar 29 05:54:57 I checked there and could only find operating temperature, which isn't exactly what I was looking for Mar 29 05:55:24 But if that's all there is that's fine too, I am able to just make the assumption that they are the same if necessary Mar 29 05:57:32 Oh. Mar 29 05:57:52 Oh. Mar 29 05:57:56 I got you now. Mar 29 05:58:06 Storing the board for later use...got it. Mar 29 05:58:30 Sorry. I am a bit slow tonight. Mar 29 05:58:36 Ah it's okay Mar 29 05:59:23 Hey sir, that is actually a good question. What temperature does the board melt or begin to decay out of antistatic bags? Mar 29 05:59:25 I got it now. Mar 29 05:59:57 Sorry for mocking you here. It is actually a good question. I do not know the answer. I am sorry. Mar 29 06:00:11 But... Mar 29 06:00:15 Well, to be more specific, I work for a nanosatellite program and we are trying to find how hot or cold our satellite can get before it'll be at risk for being destroyed. But we have found in the past that storage temperatures are close enough Mar 29 06:00:22 It's cool! Mar 29 06:00:25 Stick around, I am sure someone else knows or can account for storage. Mar 29 06:00:57 Thanks for helping! Mar 29 06:01:02 No issue. sorry. Mar 29 06:01:13 It is a surprisingly hard value to come across for any piece of hardware, actually Mar 29 06:01:39 I completely understand. Chips melt while being on or off. Mar 29 06:02:19 Let us see. Silicon on these buggers must malfunction at a specific temp. I am with you on this idea, i.e. on or off. Mar 29 06:02:55 I can tell you something. I ran a am335x pretty hot by doing some poor source etiquette on the networking side of things. Mar 29 06:03:04 It burned my hand but did not kill of the board. Mar 29 06:03:14 of = off Mar 29 06:03:37 I am actually surprised about how much oomph these boards can handle. Mar 29 06:04:01 I keep pushing. They keep taking. Anyway, I am sure you are done w/ me now. So, back to my squandering. Mar 29 06:04:30 Oof, those things get hot. Hope the burns weren't too bad Mar 29 06:04:48 Alright, I appreciate your help! have a good night! Mar 29 06:04:57 You too! Mar 29 06:05:27 No...the burns were not. I just grazed it by accident one day while programming it. Surprise, surprise. heat! Mar 29 06:06:07 It was my fault but now, I know w/ these boards if I program them incorrectly, things can go a midst. Mar 29 06:09:09 Reminds me of building a desktop a few years ago and not realizing the FX9590 was a lava furnace of a processor until after I bought all of my parts. Getting that thing to stay cool was an ordeal Mar 29 06:11:20 Yes sir...things got to stay cool. Mar 29 06:12:31 Silicon in general, or the type of it, must have some schedule to it on if it has a melting temp. and cooling malfunction temp. Mar 29 06:13:00 So, if the metal gets too hot, the silicon melts but, right, at what temp? Mar 29 06:13:38 I am not going to try to ruin my board to test but 5v on the GPIO pin will directly affect your am335x for life. Mar 29 06:15:07 it will degrade it directly for life and it will be affective immediately. I learned, sort of. Mar 29 06:16:28 I'd imagine there'd be no way to tell without knowing the specifics of the board. I would expect the transistors inside to start degrading long before any physically apparent damage took place Mar 29 06:16:44 right. Mar 29 06:19:40 I'll probably just end up assuming the operational temperature in place for a survival temperature. It doesn't seem like most microcontroller manufacturers test for that, which is unfortunate Mar 29 06:20:47 And it exceeds what we expected the operating temperature of the spacecraft as a whole would be anyway, so it would probably be fine Mar 29 09:13:32 Hi Mar 29 09:14:12 Could I get BBB PCB files from web site? https://beagleboard.org/black Mar 29 09:32:43 Wistron_Daniel: there's literally a link to the pcb files on that page Mar 29 09:33:39 all the design files are in this github repository: https://github.com/beagleboard/beaglebone-black Mar 29 09:49:39 jkridner: btw, it may be worth asking github if they can reverse the direction of the "is a fork of" relationship between beagleboard/beaglebone-black and CircuitCo/BeagleBone-Black to reflect that the former is primary... they have a special page for that: https://support.github.com/request/fork Mar 29 09:53:52 at the very least you can detach the fork... but it may be nice to maintain a link in the reverse direction so people who follow a link to the old circuitco repo can more easily find the primary repository Mar 29 10:59:56 Fly BBBlue fly! Mar 29 11:01:30 I do not know why I cannot figure this out. The binary is on the board now. The user LED (red) flashes. I set up the prerequisites, and still Blue is down. Mar 29 11:01:32 Sheesh. Mar 29 11:02:31 I have not tried everything, i.e. as I am being cautious. Mar 29 11:03:37 I only have one more left, maybe two. Who knows? Anyways, I am updating a system to TI-RT instead of armv7-rt. I will update at will. Mar 29 11:31:18 bbl! Mar 30 02:18:59 agony on the BBBlue homefront. Mar 30 02:19:21 I need...knees of gold for this to work. **** ENDING LOGGING AT Wed Mar 30 02:59:57 2022
