T1042 Uboot config for x32 DDR4

[gokulkrishnan]

Hi, 

If I am intending on using a x32 configuration for the flash. What are the changes or implications that may come up while loading the uboot. can you help me with that? Also if there are changes that I need to make in the configuration please let me know.

Regards

I am not sure what "changes" you are asking about? If you mean changes between x64 and x32 DDR interfaces, you need to properly set DDR bus width via DDR_DDR_SDRAM_CFG[DBW] register, and correct memory size (assuming the same x64 memory is used in x32 mode).

Hi,

By changes I meant the settings that I must look into. So just the DBW needs to be set right?

Yes.

Sorry, you said "I am intending on using a x32 configuration for the flash", but topic name says "x32 DDR4"

Can you clarify this discrepancy between "flash" and "DDR4"?
