I got my AVR-PG2B parallel programmer and AVR-P20B-10MHZ development board today.
I’ve been trying to program an AT90S1200 chip with a hex file with AVRDUDE. Jumper J1 is open.
Below is the output from avrdude, it fails every time, however it does seem to detect the 1200 chip(0x1e9001).
I’ve tryed changing the settings on the parallel port (EPP or ECP) and i’ve tryed using a different computer ( though that perhaps i blew the port).
Any suggestions to what i’m doing wrong?
