[avrdude-dev] stk500v2 // ATmega8

[tias]

Hi,

I experience troubles uploading any program to ATmega8, using stk500v2
and avrdude-5.0.
the upload does not succeed, also the signature is wrong (0xFF 0xFF 0xFF).

if i use avr studio in windows then the upload works ok.
(so i guess my stk500 hardware settings are ok: high voltage parallel)

the atmega8 is in socket: sckt3200A2
10pin connection between PROG CTRL and PORT D
10pin connection between PROG DATA and PORT B
1 pin connection between (right pin)BSEL2 and PC2
2 pin connection for PJUMP

my system is linux debian testing/unstable, running kernel 2.6.14.

here is the cmd and output:
$ sudo avrdude -p m8 -c stk500v2 -P /dev/ttyS0 -F -v -U
flash:w:chenillard.hex

avrdude: Version 5.0
