I have a problem with the STK500. I tried to use it to program some type of AVR. I was able to program AT90S8515, AT90S2313 with ISP, and parallel programing too. Although I am not able to program AT90S2343 8pin device. I verified its lockbits, fusebits, with an another prtogrammer device these are in the correct positions, I tried to program an another IC too. I followed exactly the User Guide steps, and notices too. The AVRstudio sent the next message:
Setting device parameters, serial programming mode ..OK
Entering programming mode.. FAILED!
Leaving programming mode.. OK
This message was when I tried to erase, verify lock bits, fuses also. It seems like the 2313 can not communicate with STK500.
Is there anybody who has good ideas to solve my problem?
