how can uboot 2020 boot in emmc mode on imx6sxsabresd board

I have an imx6sxsabresd board and want to test the latest BSP5.4. I use yocto to configure the uboot startup mode to emmc mode. After the compilation is completed, after burning with uuu, the serial port keeps outputting "data abort" and "reseting CPU". What's wrong?

 

this is output:

Hi jingyangxie

 

one can test it with Demo Image i.MX 6QuadPlus, i.MX 6Quad, i.MX 6DualLite, i.MX 6SoloX Boards

Also when building, recheck if correct machine was used, as described in

sect.5.1 Build configurations  i.MX Yocto Project User’s Guide​

 

Best regards
igor
