Hi jah,
Here is a small test programme in all assembly that I wrote to test the backdoor function.
It was written to run on a M68DEMO908GB60 board.
You load the programme then secure the FLASH.
Then cycle power and try to get back in via BDM, you can't.
Then press SW1 and now you can but your reset vector is blank.
This is because it is just a simple test programme.
Hope this helps
David
