[beagleboard] beaglebone booting
Hi I was following a guide from a following link to create a partition on SD card. I was using beaglebone Black's SD card slot to do the partition as beaglebone has Linux and contains all the packages to create partition. http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ When I gave a command to read the partition and error popped up that Re-reading of partition failed due to error 22. The kernel still uses the old partition table. It will be informed after next rebbot or running partprobe or kpartx. So I ran partprobe and kpartx but I didn't work. So I reeboted the system. And it stopped booting. Can anybody help on the problem ? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Beaglebone Black freezing, USB related?
This fixed my problem on Ubuntu. My steps are as follows. 1. sudo apt-get install cpufrequtils 2. sudo cpufreq-set -g performance 在 2013年11月27日星期三 UTC+8上午2:52:02,Dino Tinitigan写道: 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.

[beagleboard] USB1_OCn pin - who is listening?
Hiya The Beaglebone Black schematic has the over-current flag pin from the USB power controller for the USB host port connected to the AM3358's T16 pin (say, GPIO1_26). Does anybody know why? Who is listening to that pin? I can't find anything in the device manual about over-current, which suggests it needs to be handled in software. But what software? Any pointers, anyone?

Re: [beagleboard] Is BBB compatible with Arduino Sensors?
The Beaglebone black will support *anything* you can physically attach, and have a driver for. So while maybe that driver does not exist for the beaglebone black currently, you can always write one.

It is there for someone to listen to.
