Mega32P 16MHz connected to MK-II ISP. Using device programming tool within Atmel Studio 6.1.
The mega32p is one of many that came to me with a bootloader pre-installed, with the fuse bits set for a 2KByte boot size. And the lock bits were on preventing me from making a backup of this boot.
My goal was to change the fuses to use 1KB boot segment, erase and reprogram.
I changed the boot size to 1KB. Fine. Then I tried to chip erase. Error: Device ID (signature) cannot be read. I've power cycled, etc but cannot get the MK-II to see the device ID now.
Maybe I was supposed to chip erase first, because the lock bits were on?
Long time since I worked with the MK-II (USB). Could it be as simple as: I honked up the oscillator type fuses? It has a 16MHz ext. crystal.
EDIT: added info: Scope shows same 16MHz sine wave on pin 7, 8 of a a "good" board and the board that I bricked, as above. Crystal is 16MHz.
