Hello,
I ported leon3mp and noelv-generic template designs to my FPGA board.
-
LEON3 design: Both AHBUART and GRETH/EDCL debug link work fine
-
NOELV design: The AHBUART works, but GRETH/EDCL will report an error

Bad AMBA Plug n' Play values found! ERROR! GRMON Evaluation version does not support this hardware design. If a design contains GRLIB IP cores that are not distributed under GPL license, then an upgrade to GRMON professional version is required. Please consult the GRLIB IP Core User's Manual for details on IP core distribution.
The same NOELV design, since AHBUART works, it seems that the problem is not ‘GRLIB IP cores that are not distributed under GPL license’.
Would somebody have any suggestions, Thanks.
