I tried to set up external oscillator to my ATMega1284P. I calculated my FUSE value and wrote to the chip using avrdude.
This was the exact command:
avrdude -p m1284p -c atmelice_isp -U lfuse:w:0xf7:m
This is the output:
After it I connected the 20MHz crystal and the 2 x 22pF cap to the XTAL1 and XTAL2 pins, but I am not able to reach the MCU :(
What did I do wrong ?
Can I get it back ?
