I have problem using the 2343 which made it unable to be programmed.
Which situations could cause the AVR-chip to prevent programming/writting? Reading and erase is possible though. By mistake I left the RESET-pin untouched when trying to program, but this shouldn't ruin the AVR. I did verify that no security/lock bits or fuses are programmed(the erase will unprogram these), but it fails the health check. In the current design the configuration is used as described in the STK200 manual part 10.3 separating the ISP wires from the custom circuit with 1K resistors. All ISP pins are configured as inputs.
Thanks in advance.
