[arm-allstar] Software ver 1.2 and BBB ver B --- power supply woes

[David McGough]

I second these comments! 5 volt power supply problems are the #1 issue
with BBB's and stability....If you're having *ANY* wierd problems, check
the power supply first.

Personally, I've found these switching power mudules to work well, when 
attached to the barrel connector:

I was having the exact same problem with my rev. B boards and ver. 1.2 of 
Doug's release. I ended up fixing the problem by powering the board via 
the barrel connector instead of the USB port. I never had the issue under 
ver. 1.1. I have 2 rev. B BBBs, and the same issue on both boards.
Thanks!

rev B board. I got everything up and running with ver 1.2 a few nights 
ago. I had an Echolink connect running fine. The next morning the USB 
audio FOB was dark, no heartbeat LED. I unplugged the FOB, and reinserted 
it. No lights. I could login to the BBB with putty, so I restarted 
Asterisk. Still no lights. Finally I did a shutdown -r now. The BBB came 
back up with the FOB green led flashing after a min or so. I checked back 
in an hour or two, the fob was dead again. Same story, I had to shutdown 
and restart the opsys. This went on for a couple of days. Finally, I 
transferred the SD card to my backup board a BBB rev C. No problems, the 
boards been running for 2 or 3 days. I thought that the old BBB rev B 
took a crap. For grins, I reloaded the previous ver 1.1 on an SD card and 
brought up the rev B BBB board. It's been running for over 24hr with not 
a hang. It appears that the new rev

 1.2 has a problem with the old rev B BBB board. At least, it does with 
mine. Has anyone else had this problem?
