Re: [avr-gcc-list] stk500 board acting strangely

[Colin O'Flynn]

Hi,

A quick thing to test is do this:

1]Power off STK500
2]hold down "program" button
3]Power up STk500
4]In AVR-Studio goto "Tools -> AVR Prog"
5]Go to the "advanced" tab and see if you can read the
signature bytes

If you can do all that, your STk500 is probably OK. I
can send you firmware updates to reflash your device
if you get this far.
