[avr-gcc-list] Auto write calibration bytes

[Royce Pereira]

Hi,
I'm using AVRdude.

While programming, I'm trying to retreive, and then write into the 1st 4
eeprom locations,, the calibration bytes.


The device gets programmed. Also the the calibration bytes are read to the
specifie file, but fails while writing to eeprom.

The command line, & subsequent avrdude reply is reproduced below. The
programmer is set to usbasp (default).

How best to acheive this ?  Thanks.
