Hello，all

What changes do You need to make to upgrade DDR (3G) to 4G?

SCFW，UBOOT，KERNEL？

Is there any documentation for that?

Tks，

Best regards，

Grayli

Hi Wang

in uboot one can tweak #define PHYS_SDRAM parameter

imx8qxp_mek.h\configs\include - uboot-imx - i.MX U-Boot

rin ddr test i.MX 8/8X Family DDR Tools Release

For scfw copy the custom DDR CFG file to src/scfw_export_mx8qx_b0/platform/board/mx8qx_mek/dcd and build to the final SCFW. One can try to follow the steps:

1. copy custom CFG file to dcd directory

cp xxx.CFG src/scfw_export_mx8qx_b0/platform/board/mx8qx_mek/dcd

make clean

make qx R=B0 B=mek DDR_CON=xxx

May be recommended first not use OpTee, refer to sect.5.6.10 OP-TEE enablement
