Hi ZHOUNENG

seems OCRAM can be used for such purpose, i.MX8X has not SRC_GPR registers.

Hello igorpadykov

Thanks for help!

I tried the OCRAM at address from 0x00100000 to 0x0013FFFF, it seems that the value will change every warm reset. I guess maybe this memory can not survive warm reset or SCFW / ROM CODE will use and change the content when booting?

And could you please look for other possible registers or RAM? Thanks.
