Hi Community.

 

I'm making a program for the CM4 core. I would like to use OCRAM because TCM seems to lack capacity.

I think that linux doesn't seem to use OCRAM, but I didn't know if u-boot was using it.

 

Does anyone know how OCRAM is used by u-boot and linux?

 

(It is good for me that OCRAM is only used by BootROM.)
