Using avrdude and Arduino as ISP to program an Atmega

An Arduino board can be used as ISP programmer to program an Atmega chip.

There is a good tutorial here.

This post is just a quick note of the avrdude command to program an Atmega328p (MinimOSD).

For reading flash on COM4:

avrdude -P com4 -c avrisp -p m328p -b 19200 -U flash:r:READ.BIN

For writing flash on COM4:

avrdude -P com4 -c avrisp -p m328p -b 19200 -U flash:w:WRITE.HEX

Add -v for verbose output.
