The ATmega325 is listed for the addon device STK502.
i don't have that one, but i have the STK501. And, the atmega325
is pin compatible in all relevant aspects with the atmega64 (supported
on the STK501). So i tried it out, but ... no succes, i cannot
communicate with the device:
./avrdude -C ../etc/avrdude.conf -p m325 -F -c stk500v2 -P /dev/ttyS1 -t
avrdude: stk500v2_command(): command failed
avrdude: stk500v2_recv(): checksum error
avrdude: stk500v2_program_enable(): bad STK600 connection status: Unknown (0x64)
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA325 is 1E 95 05
Looking into the avrdude configuation file i see this
#------------------------------------------------------------
# ATmega325
#------------------------------------------------------------
part
id = "m325";
desc = "ATMEGA325";
signature = 0x1e 0x95 0x05;
has_jtag = yes;
# stk500_devcode = 0x??; # No STK500v1 support?
# avr910_devcode = 0x??; # Try the ATmega16 one
avr910_devcode = 0x74;
So i played around with some values of these parameters,
but no succes eigther. (0xA0; 0x45;)
But i see no fundamental reason why this is not possible.
Has anyone an idea how to make this working?
