Hi @vinothkumars,

you need the u-boot and u-boot fast boot running for flashing the emmc.

and the image flash.bin you built only has the m4. that is why flash gets fail.

if you look at the uuu help.

you will see arg0: _flash.bin bootloader and arg1: _image[Optional] image burn to emmc, default is the same as bootloader. it is optional.

So for you case, you need two arg0 and arg1. arg0 is the bootloader flash.bin has u-boot and arg1 is what you want to burn to emmc.

So you can use the binary release to burn the flash.bin you built.

uuu -b emmc imx-boot-imx8qxpc0mek-sd.bin-flash flash.bin

here imx-boot-imx8qxpc0mek-sd.bin-flash is the flash.bin with u-boot(running on A35 and has uboot fastboot). flash.bin here is you build with "make SOC=iMX8QX flash_cm4".

Israel.
