At my end u-boot 2020.04 was long broken for emmc, hope latest emmc changes should fix them all as of now. Following information for flashing u-boot images for eMMC and sd_card. # Binaries should be available in fip directory : fip/ | ... |------ u-boot.bin (for eMMC) |------ u-boot.bin.sd.bin (for SDCard) [0] https://github.com/BayLibre/u-boot/tree/readme#install-on-emmc There are two images in fip dir, hope you are flashing the correct image to emmc. I do the flash of u-boot images using the script below. $ cat flash.sh FILEB=/dev/mmcblk0boot0 DEV=/dev/mmcblk0 if [ -b "$FILEB" ]; then echo "eMMC module flashing........." sudo dd if=fip/u-boot.bin of=$DEV conv=fsync,notrunc bs=512 seek=1 else echo "microSD module flashing........." sudo dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 sudo dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444 fi Best Regards -Anand
