When I received it, I successfully downloaded a kernel and one of the
pre-canned ramdisk filesystems from the wiki to it via u-boot y-modem.
The kernel booted just fine and seemed ok. If memory serves, I used the
"poweroff" or "reboot" or "reset" command (not sure which) to shut down
the system. I may have had to remove power, I can't say for sure.
After resetting the board, I noticed that serial output had started to
degrade - minicom seemed to be receiving the same FIFO's worth of data
over and over. After a number of reboots during which I was messing with
my PC's serial hardware to see if the problem was on the PC's end, the
beagle board stopped outputting serial characters altogether.
I've noticed that I can type "reset" after waiting a reasonable amount
of time for u-boot to get to its command prompt (which I can't see).
When I do that, the USR0 and USR1 LEDs shut off, and then come back on.
It appears that the beagle is receiving characters just fine from its
UART, but it's failing to output them. I've since verified that my
minicom + serial port combo is working with a loopback test.
I've also heard audio output from the headset port, a short buzzing
sound. I presume that's normal for u-boot's audio test?
I've since written an MMC card with a MLO, uImage, and u-boot.bin, and
tried booting off that. I see the same lack of output on the serial
port, and continue to hear the same audio tone from u-boot. I can't
really tell if I actually booted from MMC, since I don't get any serial
output.
Does this sound familiar to anyone? I've tried power both from a powered
USB hub and a DC supply with the same results. I'm hoping there's
something obvious to look for before sending the board back.

my board has hit this issue yesterday.
Is it possible to drop the board to this address?
