Maximum DC Voltage Exceeded- Possible Permanent Damage

I think I screwed up. I accidentally used a 7.5V/300mA supply and now
my BB is only showing a solid green light (PWR). When I connect my 6V/
800 mA (which used to work fine before), the PWR LED goes bright-dim
and stays solid. I don't see USR0 or USR1 flash anymore.

Did I fry my board?

Yep, Boss…uhr Board is screwed…now be ready shell some dough
for a new board…

i don’t think so…according to:

Gerald Coley mentioned it can go up to 12V?

It depends on which board version you are talking about. Try a 5V supply. Make sure you get power from all USB ports if it is an -xM version. If it works you are OK. If not, request an RMA and see if it can be repaired.
