I have a problem.
My BBB unexpectedly restarts every day.
My setup:
Beagle Bone Black
Ubuntu
kernel 3.8.13
Communication UART4 (pins 11 and 13 to P9)
GND connected both
Is collecting and sending data over the UART for HUAWEY 3G modem.
I implemented:
/ sys/devices/system/cpu/cpu0/cpufreq/scaling_governor for performance
cpufreq-set-g conservative
cpufreq-set-f 800Mhz
cpufreq-set-f 1000Mhz
cpufreq-set-f 600Mhz
cpufreq-set-u 600Mhz
cpufreq-set-d 800Mhz
Nothing in the logs, at most once got this before a reboot:
kernel: [80472.395680] omap_i2c 44e0b000.i2c: controller timed October
kernel: [80472.401252] dummy 0-0034: Error -110 reading from cec: 0xfe
Has anyone seen anything like this or have any tips?
FWIW I had a similar problem. I traced it to a bad power supply.
Dave.
What applied and not yet solved:
- We change the source (brand and specification)
- Find the kernel 3:13
- I changed the power supply for external USB 3G Modem to be in place by the USB and nothing has changed
- I’ve already set N way cpufreq
My board BBB continues from time to time (hours) rebooting.
Some logs caught before reboots:
