i.MX51 SDHC CMD0 Results In Cmd Line Conflict

Working with i.MX51 SDHC and trying to issue CMD0.


Instead of resulting in CC bit set in Interrupt Status register

I keep getting CRC err and Timeout Interrupt Status bits set

which indicate Cmd Line Conflict.


I check CIHB and CDIHB before issuing CMD0 even though

only CIHB needs to be checked since CMD0 does not use the

data lines.


Anyone know how to resolve a cmd line conflict like this?


Thank you.
