hi,

modiy SCFW&uboot(include/config/imx8qxq_mek.h)  DDR 3GB-->2GB

use download 2GB.bin to 3GBDDR board,is ok,  uboot startup is 2GB.

but download 2GB.bin to 2GBDDR board,is erro,

Hi gravity

reason may be in versions incompatibility between RPA tool, SCFW, kernel and uuu versions.

So may be suggested to rebuild all image from scratch using latest revisions of

RPA tool and ddr test , SCFW and kernel as described in Release Notes document for each BSP on link

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

Best regards
