Weird problem with one of our STK500s. Was using it to program some student project boards and it has been playing up ever since.
When I power it up the LED doesn't go through its normal sequence but keeps flashing and I can't connect to the on board M32 - AVRstudio says no board connected. BUT if I remove the power jumper and re-power the board, LED goes through normal startup sequence ok and I can then reconnect the power jumper live and everything works ok. Have tried removing the micro but that makes no difference and it is programming okay.
Anybody got any ideas of what I've cooked?
