Re: [avr-chat] How to do JTAG only programming

Wow, that was quick :-)

I added the blocksize parameter to both the eeprom as well as the flash 
section. Unfortunately reading the flash with -vvvv still reports 
"block_size at addr 0 is 0".

Maybe it is because of my old avrdude version? I'm using the version 
that came with Debian Squeeze (it reports to be version 5.10).

Kind regards
