[avr-gcc-list] avrdude: Cannot program ATmega8 using JTAG ICE mkII

[Shaun Jackman]

I'm attempting to use avrdude 5.3.1 to program a ATmega8 using a AVR
JTAG ICE mkII. To help troubleshooting, the same hardware setup works
in AVR Studio. Reading the Device ID and verifying the flash works,
but writing to the flash fails. The error message is

        avrdude: stk500v2_command(): unknown status 0x80

The error message seems a little curious, since I'm not using a
stk500v2 at all, but the AVR JTAG ICE mkII in ISP mode.

Thanks for any help you can give. Cheers,
Shaun
