I got a new RevC3 beagle board, and it was working great for a while
until I started chaining usb hubs on the EHCI port. This caused the
kernel to crash and when I rebooted, it no longer booted uboot.
The only output I get is "40V" on the serial port. It prints then at
power up or when pressing the reset button.
I have a RevB beagle board also and an SD card to rescue. This board
boots fine off the sd card, just to be sure, I erased nand. Then the
revB board only printed "40T" with no sd card, and nothing else at
power up. I was still able to boot off the sd card, flash the nand,
and put uboot back in nand then boot linux with no problems.
Using the same sd card, and all combinations of user and reset key,
the revC board is still stuck. Has anyone seen this? Does anyone
know what "40V" means? How come the revB board prints "40T" when
nand is erased.. what does "40T" mean?
Thanks,

Should I request an RMA for this? I have not modified the board and I
don't think I have done anything which should have caused this issue.
I need to order parts from digikey anyway tomorrow, so I'm wondering,
if I get another beagle will I eventually get refunded for the first
one? I would rather get a replacement sooner rather than later, I
need the beagle right away.
Thanks,
Sean
