Step 1 for compiling and burning

 

Everytime I search the net for the basic steps in compiling and burning my programs. So, I wanted to record it here.

I use ATmega32 microcontroller and USBasp programmer.

Compile

$ avr-gcc -mmcu=atmega32 -Os first.c

Convert to hex

$ avr-objcopy -j .text -j .data -O ihex a.out first.hex

Before burning the hex file set the clock

$ avrdude -p m32 -P usb -c usbasp -tuF
avrdude>sck 10
avrdude>quit

Burn it to the microcontroller

$ avrdude -p m32 -P usb -c usbasp -U flash:w:first.hex

To erase the chip:

$ avrdude -p m32 -P usb -c usbasp -tuF
avrdude>sck 1000
avrdude>e
avrdude>sck 10
avrdude>quit

PS: avrdude requires administrative privilege to execute, so it is suggested to use sudo command.
