Does OUT2 (aka MCR_IENABLE) disconnect the UARTs individually, as is required for the non-AST multiport case? For the non-multiport case, I have seen some cases where test #3 fails but then succeeds when retried from ddb after a few seconds. This may have something to do with the fifo not being initialized early. I've only seen it after crashes. Brucehome | help
