I think i just blew my stk-500 ISP circuit :-(
I can't read fuses or anything , tried on several working boards.
I can speak to the stk500 , and i can even upload (upgrade) new firmware to the 908535 , and all status leds are normal + reset button works.
I haven't done any debugging yet , and hope it's not one of those small dual transistors. I would hate to fiddle with anything that small.
Vtarget is ok , and an allready programed MCU works fine in the stk-500.
I tried SPI on a STK-501 topmodule , and it works fine , but i can't read/program anything on the target.
Any hints ??
Ps: If everything fails ... Is the Dragon & STK-500 offer still on @ Digikey ??
