**** BEGIN LOGGING AT Thu Nov 14 02:59:58 2019 Nov 14 03:01:29 I am stuck at pip3 not being >= 19.0. Nov 14 03:01:59 I tried to upgrade pip in Debian but I guess I will need a virt. env. heh? Nov 14 03:02:51 pip3 install --upgrade pip Nov 14 03:04:14 Okay. Nov 14 03:04:29 I think I tried that but I will try again. Nov 14 03:05:36 you may need to log in again afterwards to ensure bash finds the right command Nov 14 03:05:51 https://pastebin.com/v4w2R4Sv is my error. Nov 14 03:05:59 Oh. Okay. Nov 14 03:06:59 that looks like you broke your system Nov 14 03:07:08 apparently because you used sudo when you shouldn't have Nov 14 03:07:24 I know. It would not allow me to use pip to install things. Nov 14 03:07:44 I was trying to update pip3 to 19.0 and it said I did not have permission. Nov 14 03:07:51 then you broke your system since it works fine normally Nov 14 03:07:59 Dang! Nov 14 03:08:01 Okay. Nov 14 03:11:26 set_: https://pastebin.com/raw/v0X3Zap6 Nov 14 03:12:23 see, no sudo, no errors, it just works Nov 14 03:13:41 Yep. Nov 14 03:13:46 I must have goofed up. Nov 14 03:14:05 and that you shouldn't use sudo pip is something I've definitely told you before Nov 14 03:14:27 I know but what are the options when it gives out permission denied? Nov 14 03:15:52 find the problem and fix it, instead of using sudo and causing even more problems Nov 14 03:17:31 Oh. Nov 14 03:17:33 Okay. Nov 14 03:17:38 I will try. Nov 14 03:36:43 -bash: /usr/local/bin/pip3: No such file or directory <<<<<<<<<< This is as far as I made it? Nov 14 03:36:59 yeah like I said you managed to break your system Nov 14 03:37:05 Okay. Nov 14 03:37:06 No issue. Nov 14 03:37:19 there shouldn't be a pip3 in /usr/local Nov 14 03:39:51 set_: can you share the output of find /usr/local -ls Nov 14 03:51:18 Sure. Nov 14 03:51:20 Please hold. Nov 14 03:51:45 is a directory Nov 14 03:52:05 -bash: /usr/local: Is a directory Nov 14 03:52:17 "find /usr/local -ls" is the command Nov 14 03:52:18 Oh. I just saw the find command. Nov 14 03:52:19 Sorry. Nov 14 03:53:12 Unlimited items. It kept printing. Nov 14 03:53:21 To console...it kept printing. Nov 14 03:53:28 It would not stop. Nov 14 03:53:30 jeez wtf is all the crap you have in /usr/local Nov 14 03:53:36 I have no clue. Nov 14 03:53:47 I did use pip3 to install many packages. Nov 14 03:53:57 Like Matplotlib, numpy and others. Nov 14 03:54:23 pip3 doesn't install anything into /usr/local unless you use sudo, which you never should with pip Nov 14 03:54:35 Okay. Nov 14 03:54:37 Okay. Nov 14 03:54:53 does "find /usr/local -type d /usr/local" produce a more manageable list? Nov 14 03:54:57 sorry Nov 14 03:55:03 "find /usr/local -type d -ls" Nov 14 03:55:06 Please hold... Nov 14 03:55:07 Okay. Nov 14 03:55:31 No. Nov 14 03:55:40 It is still blasting tons of prints to console. Nov 14 03:55:52 It seems at the pace of light. Nov 14 03:56:15 "find /usr/local -type d -ls | head -n 100" Nov 14 03:56:28 Okay. It seems to be a bunch of nodered stuff. Nov 14 03:56:28 that'll give the first 100 lines, pastebin those Nov 14 03:56:32 Okay. Nov 14 03:58:37 https://pastebin.com/kfky1wZe Nov 14 03:59:42 I got it to work. Nov 14 03:59:52 Pip3 just installed xbee for me. Nov 14 04:00:01 oh ew all that stuff is installed there... Nov 14 04:00:09 Oh. Nov 14 04:00:10 ? Nov 14 04:00:17 I bet. Nov 14 04:00:34 Yea. I got it now. All that stuff is installed there... Nov 14 04:00:47 node_modules Nov 14 04:00:50 find /usr/local -path /usr/local/lib/node_modules -prune -o -type d -ls | head -n 100 Nov 14 04:00:58 okay. Nov 14 04:02:41 https://pastebin.com/ejC06A4E Nov 14 04:04:21 I'm inclined to suggest deleting /usr/local/lib/python3.7 entirely, and just use pip3 (without sudo) to install any packages you need Nov 14 04:05:18 Okay. Nov 14 04:05:24 What other options are there? Nov 14 04:05:37 let's see what else is there... find /usr/local \( -path /usr/local/lib/node_modules -o -path /usr/local/lib/python3.7 \) -prune -o -type d -ls | head -n 100 Nov 14 04:05:46 Okay. Nov 14 04:06:35 also: ls -l /usr/local/bin/ /usr/local/sbin/ Nov 14 04:07:08 okay. Nov 14 04:07:34 https://pastebin.com/AGr0xMJG Nov 14 04:08:36 https://pastebin.com/yYip8aTB Nov 14 04:11:52 brb...sorry. Nov 14 04:13:29 yeah the easiest way to fix your mess is probably by just removing all python stuff in /usr/local, i.e. sudo rm -rf /usr/local/lib/python* /usr/local/bin/p* Nov 14 04:17:58 okay. Nov 14 04:22:08 I updated it and it does not work now. Nov 14 04:22:23 Dang it. Nov 14 04:22:26 No issue. Nov 14 04:22:35 updated what and how? Nov 14 04:22:48 pip3 install --upgrade pip Nov 14 04:22:55 also don't say "does not work", always provide full output via pastebin Nov 14 04:23:00 Okay. Nov 14 04:23:04 "does not work" is not useful information Nov 14 04:24:25 https://pastebin.com/qpvMLpQf is from two separate commands. Nov 14 04:24:35 It is upside down though. Nov 14 04:24:49 That first command was sent secondly. Nov 14 04:26:07 did you log out and back in? what does echo $PATH show? Nov 14 04:26:50 This ---> /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/home/debian/usr/local/bin/pip3 Nov 14 04:27:12 I have not logged out and back in yet. Nov 14 04:27:27 even though I told you multiple times that it was necessary? Nov 14 04:27:33 Right! Nov 14 04:27:36 I am sorry. Nov 14 04:27:45 Hey. I tried. Nov 14 04:27:53 I literally forgot. Nov 14 04:28:33 if it still fails, show the output of echo $PATH again (now that you've logged back in) Nov 14 04:28:52 Okay. I just rebooted the device. Nov 14 04:30:04 ---->>>> /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games Nov 14 04:30:30 I never asked for a reboot, doing so is pointless Nov 14 04:31:05 I figured you were right but I mistook the reboot for cancelling the terminal and opening another one up. Nov 14 04:31:49 Same issue. Nov 14 04:32:07 create a ~/.bash_profile file with this contents: https://pastebin.com/uhLwXBhL Nov 14 04:32:24 https://pastebin.com/BymZnvfR and okay. I will do that now. Nov 14 04:32:49 Hi, we are running a debian on the beaglebone blue and are having some connectivity issues. We turned off the wifi in connman with the command connmanctl disable wifi and can no longer see anything when hard wired in through MOBA XTerm and through SSHing in. Nov 14 04:33:48 how are you ssh'ing in if you disabled networking? Nov 14 04:33:51 I'm troubleshooting with JORB52 and they've just connected the usb cable to their PC to try communicating. Nov 14 04:33:51 oh right usb Nov 14 04:34:17 what do you mean by "no longer see anything" ? Nov 14 04:35:34 Im using moba xterm and tried to start a terminal using the address 192.168.7.2 port 22 with the username debian. We can no longer see anything appear in the terminal and the connection times out Nov 14 04:35:39 @zmatt: Thank you. Nov 14 04:36:49 JORB52: I assume you've tried rebooting? Nov 14 04:37:56 yes, we have tried rebooting. the normal lighting sequence also changed Nov 14 04:38:44 sounds like something broke :) Nov 14 04:39:09 you'll need to use the serial console to debug it I guess Nov 14 04:39:37 (on the blue be careful to only connect it while the blue is powered up, it does not have an isolation buffer like it does on the BBB) Nov 14 04:42:29 Ok, we will try debugging it that way. how do we go about debugging it through the serial console? (sorry, were pretty new to this) Nov 14 04:43:06 that's hard to describe since it'll depend on the symptoms observed Nov 14 04:43:25 what errors or other output you see Nov 14 04:43:50 is disabling wifi via connmanctl really all you did? because it seems very odd for that to have any impact Nov 14 04:44:15 in what sense has the led sequence changed? Nov 14 04:44:41 since that would seem to suggest a fairly serious problem that's causing boot to fail entirely, not just a networking problem Nov 14 04:47:57 yeah thats all we did. the beagle froze and kicked us off right after we disabled the wifi. the LED sequence is now all blue and just flashing in a constant pattern. On the GRO123 grouping, the 2 is flashing rapidly at a dull intensity while the 0 is flashing 2 times every second brightly and then waiting a second before repeating Nov 14 04:48:29 we are not seeing any other output. when we hardwire it in, we can not connect and the connection times out. Nov 14 04:49:42 yeah that sounds like something is going wrong in very early boot (initramfs), and I have trouble believing connmanctl caused it, but there's not really any way to guess what's going on without serial console output Nov 14 04:53:05 there were no programs running at the time. we were trying to reconnect to the internet and so we tried turning off wifi and then turning back on again with connman. I thought this would just tell it stop trying to connect to the internet but once we got there, it froze and we both lost the connection. Nov 14 06:35:34 /cl Nov 14 08:22:54 zmatt, i spoke too soon yesterday, seems your fix did the job! :) let you know in a minute to be sure, bbe is rebooting! Nov 14 08:24:43 Yes! Thanks a lot! Nov 14 10:21:15 hi guys Nov 14 10:22:30 i would know if it's possible to connect to the Beacle Bone AI a multiport usb to the usb port Nov 14 12:46:33 m Nov 14 12:55:53 kremlin you are 2 hours early in your m-ness Nov 14 12:56:01 early day today Nov 14 12:56:14 moving my lathe in Nov 14 12:56:37 oh new toys to play with. Nov 14 12:57:03 :-) Nov 14 14:22:51 How is called the video protocol/interface used by LCD7 ? (RGB + H-V sync) Nov 14 14:45:19 uncertain as to what you are asking? Nov 14 15:30:20 LCD7 uses a TFC-S9700RTWV35TR-01 display that has 24 RGB pins , Horizontal Sync and Vertical Sync , how is technically called this type of interface ? Other displays uses SPI or MCU or LVDS interfaces, how is this one named ?? Simply RGB ? Nov 14 15:32:33 parallel digital video Nov 14 15:32:42 or display pixel interface (DPI) Nov 14 15:33:54 (DPI is a MIPI standard, I'm not sure whether the output of the am335x lcd controller is fully MIPI DPI compliant) Nov 14 15:57:29 well at least the data signal numbering definitely isn't DPI-compliant except when using 16-bit output from lcdc with blue-and-red-wiring="straight" in DT, which makes the data signal numbering compliant to DPI 16-bit configuration 1) Nov 14 16:33:45 Does anyone know where I can get a 3d Model of the Beagleboard X15 for importing as a Collada file (dae) into Blender? Nov 14 16:37:30 Thank you Nov 14 16:43:37 I'm wondering if a SPI to DPI converter exists.... (not related to Beaglebone) Nov 14 16:44:58 any display that uses a command interface (such as spi/i2c) will have a controller inside that converts it to something like DPI Nov 14 16:45:23 (although it might be integrated with the actual lcd driver) Nov 14 16:46:11 note that it's not a simple matter of conversion: the chip will have to have a framebuffer that's modified via the command interface and scanned out to the video interface Nov 14 16:46:55 Do you mean a SPI display is indeed an interfaced DPI screen ? Nov 14 16:47:57 I mean at some point it needs to be converted to video, at least for most display types (I guess I'm not sure about oled, not familiar enough) Nov 14 16:50:59 okay for highly integrated small lcds my statement may be flat out wrong, now that I think of it, it might actually refresh the display line-by-line without ever serializing the pixels Nov 14 16:51:46 Do you remember my 5,7" LCD (that claims by fake eprom to be an LCD7) ? I have few of them , and I have few Arduino/Teensy based project over SPI display (usually smaller, 2.8 or 3.2), It would be nice to use them for purpose, I'm finding out it's possible.... Nov 14 16:51:55 but anyway, yeah such "converters" (display controllers) certainly exist, e.g. http://www.solomon-systech.com/en/product/MobileDisplay/Display_Controller_IC/ Nov 14 16:53:36 But mine, at last, reveals a silly request... Nov 14 17:26:30 The LCD7 is just a 7"800x480 DPI display right? Nov 14 20:34:43 GenTooMan: yes (with resistive touchscreen, a few buttons, and a led) Nov 14 21:03:04 zmatt: probably i've found what I'm looking for... https://learn.adafruit.com/ra8875-touch-display-driver-board Nov 14 21:20:46 okay whoever wrote that document needs to learn the difference between an driver and a controller, this is indeed a controller (the RA8875 datasheet also correctly calls it that), not a driver Nov 14 21:22:02 (normally the driver is integrated onto the lcd module itself) Nov 14 21:29:54 this seems like a pretty fancy display controller for smallish displays :) blitting, text rendering and graphics primitives, two layers with various blend modes (though it doesn't have enough ram to support two 16-bit color layers at 800x480), hardware cursor, two pwm outputs, 4-wire resistive touchscreen controller, key scanner Nov 14 21:39:07 that is pretty expensive, anyway.... Nov 14 21:39:42 indeed Nov 14 21:45:17 The problem (my problem) is there are a lot of fancy arduino tft projects that I would like to manage with the more powerful and display-ready unused beaglebone , but there is no way (for me) to implement into beagle due to lack of knowledge.. Nov 14 21:51:40 there are folks you can pay to help with that :D Nov 14 21:59:37 :-( Nov 15 01:51:33 https://www.linengineering.com/resources/wiring-connections/ has an idea for steppers motors w/ me using the Replicape but how do I know what 2011 wiring from China was used for my stepper, e.g. since none of anything I have read makes sense for my steppers? Nov 15 01:51:35 Sorry. Nov 15 01:53:47 From left to right: Blue, Yellow, Green, Red. Dang it. The wires cover no code I have seen. Nov 15 01:55:15 I have figured out how to test for the coils but I do not want to "plug and play" w/ the Replicape since it was $99.00. Nov 15 01:57:10 Is anyone from China or has anyone heard about Kysan Steppers and their wiring? **** ENDING LOGGING AT Fri Nov 15 02:59:58 2019
