Can i use arduino bootloader for Atmega1280 on Atmega1281?
Thanks.
I think the original MEGA had a 1280 so, yes.
The 1281 is in avrdude.conf
#------------------------------------------------------------
# ATmega1281
#------------------------------------------------------------
# Identical to ATmega1280
part
id = "m1281";
desc = "ATMEGA1281";
signature = 0x1e 0x97 0x04;
You'll need to make a boards.txt entry to reflect this stuff. Will be similar to the 1280 entry that's there now.
You also lose ports H, J, K, L and UARTs 2 & 3.
