Hi,

 

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.
