Hi,
I'm currently diagnosing a Beaglebone Black (A6A) failure. It's been
running for a few months at about 20% cpu load on average. Yesterday I was
looking into some intermittent ethernet issues (may be unrelated to this
issue) and, after power cycling it, I was not able to communicate with it
at all (not via ethernet over network, not via ethernet directly, and not
via the onboard USB ethernet connection). The heartbeat light still flashes.
The microHDMI port does not show anything on the screen (but looks like it
does have a signal).
I attached the serial port output. It seems to point to eMMC issues. Do
these error messages indicate a hardware failure or could it just be a
corrupt filesystem? I have not yet tried to flash the eMMC in order to keep
it in its current state.
Thanks, anyone who can provide insight,
Chris C
