So my boot source is eMMC which is hard wired strapped.


Now back to RCW settings datasheet says


PBI_SRC 1110 is the IFC mode


Then IFC_MODE says cfg_rcw_src[0:8] 0_0100_0000  is SD/MMC (eSDHC) are multiplexed on
{IFC_AD[8:15], IFC_CLE} --------------------------------------> this is super confused 

and this is also noted as 1 .Not valid as an RCW[IFC_MODE] encoding.


From my code warrior when I set PBI_SRC as 1110

the IFC_MODE does not have 0_0100_0000 this option at all.


(1)Can someone explains?


(2) Since I am using eMMC do I need to care about QSPI clock frequency ?



(3) I also have this error: RCW and PBI data must be loaded from the same source.
