Hi, after running some software tests, we have locked the processor. In the past, I have managed to use a uLink2 debugger to unprotect the flash, and re-gain access.

This time, the debugger won't even connect

"Cannot access Memory (@ 0xe00ffff0), Read, Acc Size 4 Byte".

I suspect we might have enabled the full protection level that locks out JTAG. Does this seem likely, or can you suggest a workaround?

Thanks Jim
