[avrdude-dev] attiny13 programming

[Z.N.]

Hi!

How can I flash attiny13 devices using avrdude?

I've tried to flash a tiny13 as if it was a tiny12, however, that didnt
work out:

bash-2.05b$ avrdude -p t12 -c dapa -U flash:w:avrledtest.hex:i

avrdude: AVR device initialized and ready to accept instructions

avrdude: NOTE: FLASH memory has been specified, an erase cycle will be

avrdude: erasing chip
avrdude: reading input file "avrledtest.hex"
avrdude: writing flash (8 bytes):

avrdude done.  Thank you.


Maybe I should modify the config file in order to avrdude to work with
tiny13? (add programming codes, but how can I know which codes should be
given to tiny13, can you give some pointers to related documents?)


Best regads,
