Hi,

   your eMMC is empty now, and no partition in it.

1. For test popuse,  Use the command to only program bootloader into eMMC.

   .\uuu.exe -b emmc imx-boot

2. Use uuu.auto script

download DEMO image from our website, pleae!

---decompress it to a directory.

---copy uuu.exe to the diretory.

---switch to windows command line, and run

> uuu.exe uuu.auto

all images will be programmed into eMMC

OR Steps below are OK

in DEMO image, in samples subdirectory, you can find file 'example_kernel_emmc.uuu'

Replace default image names to yours, and copy it to upper directory, which uuu is inside.

run the command:

> uuu example_kernel_emmc.uuu

Try it, please!

Have a nice day!

B.R,

weidong

Hi @weidong_sun  for the quick update.

I tried the example_kernel_emmc.uuu script. But, after this script got stopped.

# get mmc dev number from kernel command line
# Wait for emmc
FBK: ucmd while [ ! -e /dev/mmcblk*boot0 ]; do sleep 1; echo "wait for /dev/mmcblk*boot* appear"; done;

FBK is not working

Resolve by flash .wic image (unzipped) instead of .sdcard image
