I am using an AT90CAn128. When I use my JTAG ice mkII as a debugger, all is well. (Code cycles through lighting LED's as it should. Simple test.) If I unplug the debugger, all is well. (Code again is working as expected). If I use the JTAG ice mkII to program the device, the code does not run. And, whilst trying to figure out the issue, I verified the code the debugger loads into the device using the programmer. It did not verify! So, I am sure it is a simple problem but the solution is escaping me at the moment. HELP! :)
Tell me where I have strayed.
