Hi to all,
I've a ML506. When I try to increase the size of the RAM from XPS, during the mapping EDK gives me the following error:
ERROR:Place:864 - Incompatible IOB's are locked to the same bank 26
Conflicting IO Standards are:

DIR = BIDIR, DRIVE_STR = NR

I tried to follow the following link to solve the problem, but I did not get the expected result:
