Keyword: configuration, revision
The System ACE error led is permanently on, and the JTAG chain will not configure. This can occur if the compact flash files structure does not start at rev0 and other revisions are being used.
The compact flash file system must have contiguous addressing in each collection. The first revision should be at the address cfgaddr0, the second at cfgaddr1, etc.
In iMPACT, you must select contiguous revisions starting at rev0 for each collection.
