I'm having some difficulties with programming systems with the AVRISP on certain computers.
On some computers both the SKT500 and the AVRISP program the boards fine, but on some AVRStudio (3.55) detects the AVRISP but just plainly fails to even start programming the target. The STK500 will program the target using that computer.
The target is powered up and the AVRISP is working and detected, so what would prevent it from programming????? The reset line doesn't even go low. (pull up resistor is sized properly) AVRStudio gives the usual unspecific FAILED... message.
I always thought the AVRISP was using exactly the same programming hardware as the STK500, but I'm not convinced here.
I would like to know what's going on just in case a problem arises that requires people to go out and do field updates. The SKT500 is not really rugged enough for that.
