Hi,
I am trying to use PonyProg and the AVR ISP (STK200/300) parallel port interface to program an Atmel Tiny12 chip. However, I wouldn't be able to program it and I got a 'Write error (-21)' error message from PonyProg. I look at the SCK, MOSI, MISO, and RESET pins and they all have signals. Does anyone have this problem before?
By selecting AT90S2313, the same setup will program an Atmel AT90S2313 chip.
Thanks, feilip
