Hello
I have success the booting with SD card on ab2 board.
But I failed to booting with eMMC on ab2 board.
Below is the command I use to flash emmc.
uuu -b emmc_all imx-boot-imx8mnddr4ab2-ab2.bin-flash_ddr4_evk fsl-image-af-littlekernel-imx8mnddr4ab2-20220110053440.rootfs.wic
I want to know what command and what image file to use to download emmc to make booting successful.
thanks
Bryan
should be the same images as you flashed to your sd card, what error do you get when you boot the board? did you flash the same images to the sd card successfully?
Hello joanxie
On SD card, I use below commands.
$bzip2 -d fsl-image-af-littlekernel-imx8mnddr4ab2-20210810094239.rootfs.wic.bz2
$sudo dd if=fsl-image-af-littlekernel-imx8mnddr4ab2-20210810094239.rootfs.wic of=/dev/mmcblk0 bs=1M conv=fsync
and I have attached error log for emmc boot fail.

the command you use is correct, how about using this command to flash images to SD card? does it work?

this should be your emmc issue, you need to check that, the images are fine
