**** BEGIN LOGGING AT Sun Sep 23 02:59:59 2018 Sep 23 04:49:23 set_: pull up the data sheet for the meanwell. alot of their stuff that ive had hands on has two ratings. one is max w/out active cooling and the other is max at some specified CFM value. generally speaking though their numbers are actual numbers and not imaginary numbers in my experience Sep 23 05:15:06 Okay! Sep 23 05:15:40 This power supply I have is 60w. Sep 23 05:16:08 I was thinking that there may have been a mistake b/c 160w seems like a lot of power for a small 3D Printer. Sep 23 05:18:42 Just for recap, the power supply does state 60w. This is not my concern. I have to attach this new, freshly purchased, power supply of 160w 12vDC into the board. Sep 23 05:18:42 ... Sep 23 05:18:47 This was my concern. Sep 23 05:20:07 ... Sep 23 05:20:40 j0rd: I am attaching a SaberTooth 2 x 12 right now. Please hold. Sep 23 05:29:15 I got the SaberTooth to work, yea! Sep 23 05:30:27 I think the BBGW needs to have more than just one UART connected to the one connector on the Sabertooth for usage of two motors. Sep 23 05:30:28 ... Sep 23 05:30:37 I could only get one motor to turn for some reason. Sep 23 05:31:25 Help Needed!! I bought a BeagleBone Black and set a password that I forgot. I'm trying to flash the emmc using the steps described in the guide but it doesn' t work. As I cannot login I cannot modify the uEnv.txt file. Any suggestions? Thanks. Sep 23 05:31:43 Yea. Sep 23 05:31:47 temppwd! Sep 23 05:31:51 Vish: "doesn't work" ? Sep 23 05:32:32 I changed the password when I first logged in, so "temppwd" wouldn't work anymore right? Sep 23 05:32:35 also, you can boot from sd card and use that to reset the password on eMMC without reflashing Sep 23 05:32:42 ignore set_ Sep 23 05:33:12 Ignore me. I missed the way to understand. Sorry. Sep 23 05:33:47 Vish: zmatt knows his way around the BBB. Serious. Sep 23 05:34:01 Doesn't work: The lights flask infinitely, never stabilizes. Sep 23 05:34:41 Vish: also, what does your inability to login on eMMC have to do with modifying the /boot/uEnv.txt file on the SD card? Sep 23 05:34:42 set_: Haha, thats nice. I'm in good hands! Sep 23 05:34:56 Vish: that sounds like you're not flashing at all Sep 23 05:35:20 if you've booted from sd card you can login as debian/temppwd Sep 23 05:35:54 So, that puzzled me too, I can't file /boot/uEnv.txt when I browse the beagle bone through the file explorer. Sep 23 05:36:35 then do sudo nano /boot/uEnv.txt and uncomment the last line (meaning remove the # at the front of the line) Sep 23 05:36:39 file explorer? Sep 23 05:38:13 Ok, If I got this right, I need to modify the /boot/uEnv.txt file on the SD card with the new image. Sorry, my bad I thought the file should exsist in the beagle bone directory. Sep 23 05:39:42 yes. if you have a linux host system you can modify the file on the sd card directly before booting the bbb from it. otherwise you can boot the bbb from the sd card, log in, modify it, and reboot Sep 23 05:42:37 Yea! Sep 23 05:42:47 Now, that is some good info! Sep 23 05:43:15 Oh well. Sep 23 05:43:21 alternatively, instead of reflashing eMMC you can also reset the password directly with something like this: https://pastebin.com/vKVgQNwL Sep 23 05:43:29 oh, gone Sep 23 05:43:57 zmatt: Do you remember me asking about using the SaberTooth w/ the BBB? Sep 23 05:44:11 what's that? Sep 23 05:44:15 Oh. Sep 23 05:44:17 Wait. Sep 23 05:44:20 I will show you. Sep 23 05:45:01 https://www.dimensionengineering.com/products/sabertooth2x12. Sep 23 05:45:20 oh that thing Sep 23 05:45:33 That is what I am using to perform motor action from control from the BBGW. Sep 23 05:45:34 ! Sep 23 05:45:56 Yep. Sep 23 05:46:00 I got it to work. Sep 23 05:46:31 config-pin P9.24 uart and config-pin P9.24 uart worked like a charm. Sep 23 05:47:03 I could only get one motor turning so far for some reason. Sep 23 05:47:14 I was using someone's library. Sep 23 05:48:28 https://github.com/MomsFriendlyRobotCompany/pysabertooth is what I found. Sep 23 05:51:48 zmatt: Sorry, Lost connection to the Wifi. I looked at the /boot/uEnv.txt file in the SD card. And It doesnt contain any line that starts with "cmdline" is that normal? Sep 23 05:52:15 are you sure you scrolled all the way down? Sep 23 05:52:21 it should be the last line Sep 23 05:52:42 Yes I did. The last line starts with # and is blank after that. Sep 23 05:53:19 here's what you missed btw: https://pastebin.com/A8zDkffe Sep 23 05:53:30 which image did you flash to sd card exactly? Sep 23 05:55:35 Thanks for the history. I used this image from beaglebone.org/images : Debian 7.5 (BeagleBone Black - 2GB eMMC) 2014-05-14 Sep 23 05:55:53 please don't use some prehistoric ancient image Sep 23 05:56:39 it's no surprise current instructions are not going to work for those. I have no idea how flashing those worked Sep 23 05:57:00 Haha! That was the only one listed under the BeagleBone Black (eMMC flasher) section! Any other source for the image. Sep 23 05:57:41 I have no idea where you looked. just download the latest image from https://beagleboard.org/latest-images (first download link under "Recommended Debian Images" Sep 23 05:59:05 zmatt: The same webpage has a section called "BeagleBone Black (eMMC flasher)", I assumed I need to use this to flash. Sep 23 06:00:00 7.5? Yikes! Sep 23 06:00:34 no, you just follow the instructions immediately below the download links in the "Recommended" section on that page, telling you how to modify /boot/uEnv.txt Sep 23 06:00:55 or follow the link to the wiki for a premade flasher Sep 23 06:01:58 Yes just read that, Thanks a ton! In case it doesn't work, I'll use your instructions in paste bin to log via SD card and change the password. Sep 23 06:02:44 this is my first interaction with the BBB, I've always used Pi so getting to know my way around here. Sep 23 06:03:20 note that once you modify /boot/uEnv.txt on the sd card, it will now be a flasher card and you will no longer be able to boot it normally or login on it Sep 23 06:03:41 all it'll do is reflash eMMC and then power off again Sep 23 06:04:35 Yes got it. Thanks. Sep 23 08:30:08 Hello Sep 23 08:34:00 *slowclap* Sep 23 09:30:21 Hello folks, Sep 23 13:12:55 if I am using UART1 on the BBB, P9.24 and P9.26, how can I tell what address is my UART1? Sep 23 13:13:34 what are all ic's that we interface with beaglebone Sep 23 13:16:46 set_: what do you mean by "address"? Sep 23 13:17:32 I am receiving an address issue w/ my software that I think is related to an address of the UART1. Sep 23 13:17:59 I used config-pin and what was given as an example worked. Sep 23 13:18:03 But... Sep 23 13:18:33 zmatt: I really do not know. Sep 23 13:19:28 stop asking such vague questions. if you're getting an error, give the exact error you're getting along with whatever it is that's producing the error Sep 23 13:19:54 Okay. I am getting headaches right now. Onto easier stuff. Sep 23 13:19:55 ... Sep 23 13:19:59 I will ask later. Sep 23 13:22:12 bbl Sep 23 20:56:07 tbr: allpcb.com has free dhl shipping for pcbs... Sep 23 20:56:48 tbr: I just ordered 30 pcbs for a little test project, $23 including shipping Sep 23 21:13:14 thinkfat: yeah, things are ridiculously cheap Sep 23 21:13:43 and then you'll pay 27eur customs handling to dhl... Sep 23 21:16:12 insane Sep 23 21:16:26 seeed also seems to have dropped their prices Sep 23 21:16:44 oshpark - same as always, but purple Sep 23 22:10:40 hi! could anyone tell me the path to the device tree source file (.dts) :) ? Sep 23 22:15:04 I could only find am57xx-beagle-x15.dts and am57xx-beagle-x15-revb1.dts, but not for rev c Sep 23 22:25:49 nvm, I did a git pull and found it Sep 23 22:27:46 where should I put the .dto file to be loaded though? Sep 23 22:33:08 where should I put the .dtb, is what I meant Sep 23 23:54:49 maggie? Sep 24 00:43:39 hi Sep 24 00:48:10 Do I need to add 0v (GND) and 5v (power supply) from the BBGW to the Sabertooth 2 x 12 to run motors? Sep 24 00:48:47 I think this is my mistake. I followed some instruction b/c the idea was that the BBGW only supports 3.3v out. Sep 24 00:49:09 So, 5v out was not needed from the BBGW. Sep 24 00:50:01 The instructions on the Sabertooth are add GND. Sep 24 00:50:28 It did not say to add 5v or 3.3v in supplement of 5v. Sep 24 00:50:40 I guess I can test it. Sep 24 00:58:36 Scratch what I typed. Sep 24 00:58:37 ... Sep 24 00:58:43 Forget what I am asking. **** ENDING LOGGING AT Mon Sep 24 02:59:59 2018
