**** BEGIN LOGGING AT Mon Dec 18 03:00:02 2017 Dec 18 16:20:45 totally bricked bbb. how to reflash all. Dec 18 16:22:54 https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Flashing_eMMC Dec 18 16:23:30 though actually, the easier way is to download a pre-made flasher image, flash that onto SD card, and boot the BBB from that Dec 18 16:24:36 you can find those on the same wiki page, search for "Flasher: (stretch-iot)" (or "Flasher: (stretch-lxqt)" if you really need the gui version) Dec 18 16:27:22 i appreciate the response. i have been trying to flash different images with no luck. i will try this. does a flashed image also flsh the bootloader and other partitions of eMMC? Dec 18 16:27:31 yes Dec 18 16:28:04 thank you zmatt, i will go and try this. Dec 18 17:04:54 zmatt - tried a 4gb stretch flasher iot. no luck, just a blue power light. i am pressing the reboot button, but nothing happens. NO LUCK Dec 18 17:12:45 on recovering bricked BBB. only get blue power light. nothing else. Dec 18 17:21:19 howard_: and how did you prepare the SD card? Dec 18 18:41:08 I'm working on an ADC test bench, controlled by a beaglebone. I'm using a teensy LC plugged into the BBB's usb port and using the teensy's DAC as test input to my ADC Dec 18 18:41:58 I was getting some strange intermittent values, and have traced it back to a 33khz spike on the 5v usb line to the teensy, which is in turn passed onto its DAC output Dec 18 18:42:38 I googled 33khz usb beaglebone but didn't find anything. Anyone seen anything similar? Dec 18 18:42:56 I do have a 4d systems tft panel plugged in. Maybe it's that. Dec 18 18:51:51 * tbr wonders if zmatt has seen something like that Dec 18 18:52:27 then again it's the Unlimited Source of Bugs thing involved Dec 18 20:20:11 howard_: it doesn't even boot from sd card? are you sure you flashed the card properly? also try powering on with the S2 button held down (this forces the bootloader on eMMC to be bypassed) Dec 18 20:21:07 mattvenn: what's the hsync frequency of your display? Dec 18 20:21:42 also, how are you powering the bbb? Dec 18 20:21:50 since the 5v comes basically straight from there Dec 18 20:22:11 so you could just be seeing the switching frequency of your power supply Dec 18 20:23:06 what's the amplitude of the ripple you're seeing? Dec 18 22:42:03 heyo. i've got a beaglebone black wireless that I've flashed debian stretch iot onto the emmc. i'm having a problem getting wifi working though. Dec 18 22:43:02 I'm having a problem with the connmanctl program and getting it to enable wifi. this is what it tells me when i put 'enable wifi': Dec 18 22:43:03 Error wifi: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist Dec 18 22:43:40 i tried updating the system using a usb to ethernet adapter but i still get the same error. **** ENDING LOGGING AT Tue Dec 19 03:00:01 2017
