I/O Set Violation is always occurred when mmc0_sdcd "SD Card Detect" pin is selected.

Hi,
 On pinMuxTool v2.3.1.0,  "I/O set Violation on MISC" is always occurred, when mmc0_sdcd pin is selected on AM335xZCZ.   mmc0_sdcd are assigned three pins, "A13, "C15","M17", but same phenomena are observed on all pins.   I think this pin mux tools are wrong.   Could you please check this tool?   If yes, we can not use mmc_sdcd function.
 
 Also, I seem that mmc_sdcd/mmc_sdwp on all slots are also same situation.  Could you please check it?
 
P.S. On pinMuxTool v2.2.1.0 (old version), I have not observed this phenomena yet.
 
Thanks and best regards,
 M.HATTORI.
