Look here:
ATmega164A 0x1E 0x94 0x0F
ATmega164PA 0x1E 0x94 0x0A
ATmega324A 0x1E 0x95 0x15
ATmega324PA 0x1E 0x95 0x11
ATmega644A 0x1E 0x96 0x09
ATmega644PA 0x1E 0x96 0x0A
ATmega1284 0x1E 0x97 0x06
ATmega1284P 0x1E 0x97 0x05

These are the signature bytes for the different chips.
My version of avrdude.conf has two '324 chips:

#------------------------------------------------------------
# ATmega324P
#------------------------------------------------------------

# similar to ATmega164P

part
    id               = "m324p";
    desc             = "ATMEGA324P";
    has_jtag         = yes;
    stk500_devcode   = 0x82; # no STK500v1 support, use the ATmega16 one
    avr910_devcode   = 0x74;
    signature        = 0x1e 0x95 0x08;

and

#------------------------------------------------------------
# ATmega324PA
#------------------------------------------------------------

# similar to ATmega324P

part
    id               = "m324pa";
    desc             = "ATmega324PA";
    has_jtag         = yes;
    stk500_devcode   = 0x82; # no STK500v1 support, use the ATmega16 one
    avr910_devcode   = 0x74;
    signature        = 0x1e 0x95 0x11;

You can change one of those to match your device's bytes, then select the board with that chip type.

I tried to use atmega324p and it gives a list of supported chips

4

i tried using the m324pa with it I get the same ?

5

Did you change the signature bytes in avrdude.conf to
0x1E 0x95 0x15
to match your chip, ATmega324A ?

no Ill try that ....rite now
