Hi All,
Got my Bone Black today and all seemed well. It booted as expected and I was able to log in, create a new user and so on. I was unable to SSH and so I thought I would make sure that I had the latest production code before going any further with testing the board.
Downloaded BBB-eMMC-flasher-2013.04.13-DDR3-400MHZ.img.xz from Circuitco's website. I don't have access to a Windows machine, so I use xz -dkc BBB....img.xz > /dev/sdc to decompress and save the image to my uSD. That seemed to go well as I can mount on my Ubuntu machine and see all the files without any problem.
I inserted the card on the black, held the boot button down and applied power. It booted normally all the way to the user prompt, and I think started the eMMC flash program. A few seconds later I got a kernel panic message. The bizzare part is now it is not reliable at all when I try to reboot. It would simply hang at different points in the boot process. If I leave the board un-powered for several minutes, it will at least boot to the prompt and start eMMC flash. Sometimes I won't get any kind of message; it will hang with LEDs on.
I tried version 2013.04.12 as well with the same result.
It is beginning to smell like a hardware issue with the board. Anyone else seen this behavior?
