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,

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
2.
make clean
3.
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
i.MX Yocto Project User’s Guide
Best regards
igor
