[avr-gcc-list] STK500 Acting Funny

[User Tomdean]

I have been using an stk500/atmega16 on FreeBSD 5.4, with avr-gcc
(GCC) 3.4.3, avrdude: Version 4.4.0, as happy as can be.  Suddenly, I
cannot program the atmega16.  I can communicate with it on the spare
UART port and the same FreeBSD serial port.

However, I can program the atmega16 with the AVRStudio on Windows!
Very strange.  With a scope, things look OK.

I upgraded the stk500 firmware, just in case...  No change.

Any ideas?
