Hi all, I think I *may* have a potential fix.
I've had the same issues with my logitech c920 and my usb wifi adapter. I have a java program that takes a webcam image using opencv and then it is uploaded to my server. When I skip either the capture or upload part of my program it is completely stable. However combined it freezes after about 15-30min. When I look at the beaglebone black the leds are no longer flashing. Anyway, this has taken me two weeks to have a potential solution. looking at the dmesg output i get: [ 943.043325] omap_i2c 44e0b000.i2c: controller timed out [ 944.053233] omap_i2c 44e0b000.i2c: controller timed out [ 945.063042] omap_i2c 44e0b000.i2c: controller timed out [ 945.069066] tps65217 0-0024: Read from reg 0xf failed [ 946.074832] omap_i2c 44e0b000.i2c: controller timed out [ 946.080862] tps65217 0-0024: Read from reg 0x11 failed *[ 946.086629] cpufreq_cpu0: failed to scale voltage down: -110* It seems that the cpu voltage is being or attempted to be scaled down. I then tried to change the my cpufreq governor to performance and that seemed to have fixed it. root@beaglebone:~# *cpufreq-set -g performance* btw. I am using angstom with kernel 3.8.13 my BBB has now been running without freezing for 14 hours which is 13.5 hours more than before. hopefully this fixes your guy's freezing problems as well. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
