Hi,
The debugging limitation will return this message when the PC gets over the 32K limit. (ignoring the first four bits of the address)
You receive this message because for some reason your PC gets at address 0x1FFFB020.
If you had the RLink PRO, without limitation, you would get a different error message but still it wouldn't work because this address is not valid.
You must understand why your PC goes at this wrong address...
Try debugging your startup code for a start.
I cannot tell much more without information on the board and application.
If it is a standard board, try debugging the standard applications designed for this board.
If it is your custom board, try to find differences between your board and standard ones. Try also debugging very simple toggle aplications to start with.
I also suggest you perform a search in this forum, and also on this other one:

Some other customers had problems that lead to this error message... You will find hints and ideas there.
Best Regards,
Vincent
