**** BEGIN LOGGING AT Sat Apr 25 02:59:59 2020 Apr 25 03:01:16 Okay. yes. Apr 25 03:02:15 If that is how you say it, why is 0.5A per servo && 4A per 8 servos only having so much resistance? Apr 25 03:02:44 b/c of the traces? The trace is too tiny to handle the amps? Apr 25 03:04:36 I am shooting in the dark here b/c I do not know what you have onboard. Apr 25 03:04:55 I made the traces fairly wide and where I couldn't I put 2 traces to the pins. The traces are for 4A but each subcircuit is limited to 2A continuous Apr 25 03:06:51 So, you have an amps at 4A hitting a 2A circuit and this is what we are discussing? Apr 25 03:07:39 Let me go and watch the video of how amps works again. I must be missing something. Apr 25 03:09:41 Is it an issue? It is like cramming a ton of amps into a large wire and expecting the smaller diameter wiring to work similarly at the same amount of amps? Apr 25 03:09:57 Right? Apr 25 03:13:19 So, the 2A subcircuit is getting fed 4A and this is the issue. Apr 25 03:14:41 What is one of those subcircuit CMOS parts called? Apr 25 03:16:54 Now, as @zmatt has pointed out, I "know nothing" about programming chips. So, if you ever need help w/ the STM32, I am out b/c I refuse to reiterate more loops, functions, and classes. I know there are more ideas to it than that but I am at a refusal stage in life w/ software mfg. Apr 25 03:27:43 Ok .. well the STM32 has 1M of flash and 320k of SRAM and 16M of external SPI flash. I plan on implementing some standard simple algorithms in it for motion control. the primary thing is controlling and updating information on each servo simultaneously. Apr 25 03:31:59 It seems very difficult. I hope things go well. I am not sure how to simplify that well on this venture. Apr 25 03:33:05 I mean, at some point, there are the i2c/uart functionality of the Cape being controlled via the BBB and this, so you say, issue w/ the 4A per 8 motors. Apr 25 03:33:06 ... Apr 25 03:33:14 I guess it depends on the motors too, right? Apr 25 03:36:10 mostly those things you have been asking about are handled by the servo, IE capacitors etc. are usually in the servo. So it depends on the servos in reality. If I were to directly control the motors that is a bit more complex. I actually studied what goes on how they work etc. Apr 25 03:36:47 Oh. Apr 25 03:37:15 So, you already did the work of the internals of servos. See, me, I have not (yet)! Apr 25 03:39:45 Well there are a lot of things that are involved "digital" servo's using a microcontroller to handle the position motor movement etc. The other servo's use an integrated circuit designed for that specific function. Apr 25 03:41:13 Oh. So, some of them are continuous and need external circuitry/controllers for movement? Apr 25 03:41:29 I only know so much about them. Apr 25 03:42:16 I wanted to jump in fully but I have not gotten my hands on a book that I have read that has gone into depth on the subjects pertaining to servos and the functions. Apr 25 03:42:46 Now...do not get me wrong. My fault, I know but... Apr 25 03:43:38 I figured one of the books would have been dedicated to motors more than just software engineering. There is so much to learn and read. It is hard to settle for one subject during the course of a period. Apr 25 03:44:37 GenTooMan: I just received an email. They were trying to sell me concealer and spunges. Apr 25 03:44:38 Odd? Apr 25 03:44:56 Just for kicks, I am male. Apr 25 03:46:21 hmm well you need to conceal yourself... from whatever it may be! Apr 25 03:46:40 paranoia is not out of style yet... Apr 25 03:50:10 Not like that. Apr 25 03:50:19 It is make-up or something. Apr 25 03:51:17 GenTooMan: How invested are you in your Cape? Apr 25 03:51:38 concealor my guess is for hiding flaws in the skin. Like "how fake are you now? Apr 25 03:52:14 Super? Apr 25 03:55:53 Oh. I got you now. Fake. Super fake w/ clown skin. Apr 25 03:55:54 Ha. Apr 25 04:05:13 GenTooMan: I am still reading about alsa on wiki.gentoo.org/wiki/ALSA. Apr 25 04:07:42 ALSA is a tricky system. Sheesh. Apr 25 04:07:54 rules and restarts galore. Apr 25 19:02:41 === Hi === Apr 25 19:05:08 I have a question now when trying to duplicate n SD card after doing e2fsck -f /dev/mmcblk0p1 then resize2fs -M /dev/mmcblk0p1 I get prompted to do the e2fsck again... Apr 25 19:28:51 that's odd Apr 25 19:31:53 can you copy-paste the two commands and their full output into pastebin.com ? Apr 25 19:32:11 (and any commands performed inbetween those two, if any) Apr 25 19:53:20 Can't just now the BBB is down. Will do when it's back up. Apr 25 20:26:09 zmatt, it's here https://pastebin.com/Vr8LNABh Apr 25 20:29:18 uhhh okay that's fascinating. does a second e2fsck -f /dev/mmcblk0p1 fix the problem? Apr 25 20:32:26 Same results over and over Apr 25 20:35:21 date -R; dumpe2fs -h /dev/loop0p1 2>/dev/null | grep 'mount time' Apr 25 20:36:59 if the mount time is in the future (which can happen if the bbb is unable to sync to ntp) then apparently you can get this issue too Apr 25 20:39:31 I'll checl that but in the meantime I ran e2fsck /dev/sda1 and http://paste.debian.net/1143012/ Apr 25 20:40:24 Got Sat, 25 Apr 2020 16:39:51 -0400 Apr 25 20:40:40 and the last mount time? Apr 25 20:41:20 and that paste shows the filesystem was truncated (presumably because you didn't shrink it and as a result it didn't fit on the destination) Apr 25 20:42:16 Last mount time of what? Apr 25 20:43:03 oh sorry, I meant /dev/mmcblk0p1 of course not /dev/loop0p1 ... I just used that for testing Apr 25 20:43:38 Oh maybe 2 hours ago Apr 25 20:45:15 Hi set_ zmatt and I are going over a problem Apr 25 20:45:26 the command I gave prints the current timestamp and the last mount time (except I forgot to change "/dev/loop0p1" to "/dev/mmcblk0p1", so it didn't work for you) Apr 25 20:46:29 Let me check it again then Apr 25 20:47:12 Hello! Apr 25 20:48:40 Results here http://paste.debian.net/1143013/ Apr 25 20:48:40 jello Apr 25 20:49:06 What are you hound dogs doing? Apr 25 20:49:41 Trying to copy SD card having issues Apr 25 20:49:51 Dang. Apr 25 20:49:54 Oh. Apr 25 20:50:00 Okay. Apr 25 20:50:09 set_ see zmatt, it's here https://pastebin.com/Vr8LNABh Apr 25 20:50:31 Hmm. Oh. paste. Okay. Let me take a gander. Apr 25 20:51:20 I am new here. I do not know what is actually going on w/ you all. Apr 25 20:51:26 So... Apr 25 20:51:45 In that last link, the pastebin.com link, it says what to run first. Apr 25 20:52:00 Did that not work? Apr 25 20:52:50 KenUnix: change grep 'mount time' to grep -iP 'mount time|last checked' Apr 25 20:53:15 I ran e2fsck then resixe2fs then it asked me to again run e2fsck Apr 25 20:55:53 zmatt, ok it's here http://paste.debian.net/1143014/ Apr 25 20:58:17 KenUnix: okay something wonky there, the last checked date is in the future Apr 25 20:58:28 so the kernel timezone is somehow wrong Apr 25 20:58:34 I think Apr 25 21:00:13 Date says Sat Apr 25 16:59:45 EDT 2020 Apr 25 21:00:51 How do we un-wonky it? Apr 25 21:01:06 Sometimes, that happens on my board too. Apr 25 21:01:27 So, it prevents me from updating/upgrading my board. Apr 25 21:01:30 But the date is correct Apr 25 21:01:45 Oh. Apr 25 21:01:56 So, just the time? Apr 25 21:04:58 However now running apt update hangs when going to 45.33.2.10 that's a repos-rcn site where does you apt update go? Apr 25 21:06:09 set_ 0% [Connecting to repos.rcn-ee.com (45.33.2.10)] Apr 25 21:06:37 I had that issue before. Apr 25 21:07:05 I used, which I know you do not do, sudo dpkg-reconfigure tzdata. Apr 25 21:07:23 That allows you to set the timezone and country. Apr 25 21:07:48 But the date/time TZone is correct. Apr 25 21:07:55 After that, after I use sudo dpkg-reconfigure tzdata, it then works and updates/upgrades. Apr 25 21:08:01 Try it before you knock it. Apr 25 21:08:31 Instead of America, use US. Apr 25 21:08:57 Then, you can pick generic timezones (central and etc). Apr 25 21:10:20 KenUnix: can you compile and run this little program (which checks the kernel timezone): https://pastebin.com/xYi8mAF1 Apr 25 21:10:30 interestingly mine is in UTC (on my laptop) Apr 25 21:11:21 KenUnix: I'd also like the output of timedatectl status Apr 25 21:11:50 set_ OK here it is http://paste.debian.net/1143015/ Apr 25 21:15:09 zmatt, here it is http://paste.debian.net/1143016/ Apr 25 21:17:33 wait I'm blind, the last checked in http://paste.debian.net/1143014 isn't in the future, it's almost a month in the past Apr 25 21:18:30 It's been running quit well Apr 25 21:18:47 Can we un-wonky it? Apr 25 21:23:14 can you run my command without the | grep ... then run: Apr 25 21:23:21 e2fsck -f /dev/mmcblk0p1 ; echo $? Apr 25 21:23:28 and then run my command again Apr 25 21:23:41 and make a paste of the whole shebang Apr 25 21:24:47 Results on dump http://paste.debian.net/1143017/ Apr 25 21:26:51 KenUnix: I know I do not know how to fix it. I do remember a while back, I came across this issue w/ my current set up. Apr 25 21:27:13 I could not fix it w/out the command I showed but once that command stop working, I had to get a new image. Apr 25 21:27:21 zmatt, results http://paste.debian.net/1143018/ Apr 25 21:28:04 wait now it looks fine Apr 25 21:28:44 and it refuses resize2fs -M ? Apr 25 21:29:11 Let me retry it Apr 25 21:47:17 Am going through whole procedure. I'll be back... Apr 25 21:52:00 Final result (so what fixed it?) http://paste.debian.net/1143020/ Apr 25 21:53:23 nothing.. we didn't do anything other than dump some info Apr 25 21:56:55 I'm confused. I put the copied SD into BBB and it boots fine/\. Apr 25 22:04:13 Thanks zmatt Apr 25 22:04:43 I came across this neat program today : https://pastebin.com/xZjanz9R Apr 25 22:24:17 I ot dropped again Apr 25 22:26:31 I'm not Unix70 ??? WTF Apr 25 22:36:03 Testing, 1, 2, Testing. Apr 25 22:36:06 Ha. Apr 25 23:45:06 sorry sir we are all in a sorry state of existance Apr 26 01:46:54 GenTooMan: Hello! <<< something refreshing Apr 26 02:02:59 gratings and salivations. Apr 26 02:11:37 Are you doing alright today, GenTooMan? Apr 26 02:19:47 I have been reading about ldconfig and shared libraries. Apr 26 02:24:28 It is interesting how things need to be reinstated each time files get changed. I think they call them soname and real name. Apr 26 02:25:41 Maybe this is what KenUnix was going through w/ his libs? Apr 26 02:31:42 each time you change the DLL's you must run ldconfig true. Apr 26 02:32:02 Oh and yep. Apr 26 02:32:19 Who would have thought that rule applied to some stuff? Apr 26 02:35:14 DLLs! Apr 26 02:51:25 yeah... Apr 26 02:53:55 actually it just makes sense but I digress **** ENDING LOGGING AT Sun Apr 26 02:59:57 2020
