Já mám zase tenhle problém. Zkoušel jsem to nahrát přes ponyprog ve win - nahraje se ale nespustí se. V avrdude v linuxu - mu to napíše:
kalamita3@ubuntu:~$ sudo avrdude -p m8 -c STK200 -U flash:w:blink.hex
avrdude: AVR device initialized and ready to accept instructions
Reading | ################################################## | 100% 0.00s
avrdude: Device signature = 0x1e9307
avrdude: NOTE: FLASH memory has been specified, an erase cycle will be performed
To disable this feature, specify the -D option.
avrdude: erasing chip
avrdude: reading input file "blink.hex"
avrdude: input file blink.hex auto detected as invalid format
avrdude: invalid input file format: -1
avrdude: write to file 'blink.hex' failed
avrdude: safemode: Fuses OK
avrdude done. Thank you.
