[AVR club] Cannot program the ATmega128 using SPI programming - pragnesh_pavan - Apr 24 11:15:54 2007
hi, group
i m facing very strange problem,i made my own ISP programmer and i m
using the AVRDUDE as my programming software. now i found very strange
problem when i am trying to program the IC.
at first my PEN pin is connected to the VCC.now i am trying to program
the IC but avrdude gives the error that device is not initialized.
but after that my connect PEN pin to GND and turn off the supply to
the board and again turn on the supply and my IC get programed but it
recently downloaded program is not execute even if i m reset the board.
now after this i connect PEN pin to VCC again and turn off the supply
to the borard and turn on it again now my previously donloaded program
is executed.
my question is that is it necessary to connect the PEN? or make it
left unconnected.
thanks in advance.
regards

Are you using MOSI/MISO? If so that's your problem. For some bizarre
reason, the ATMega128 uses PDI/PDO for programming rather than
MOSI/MISO.

No, i am using PDO and PDI pin for the programming insted of the
MOSI and MISO.
