iot2050 canot start

iot2050 can not boot form emmc, without sd and usb

=======================

Also can not boot form sd and usb0

when I select "run bootcmd_mmc0"

when I select "run bootcmd_usb0"

.....

what can i do in next? 

the sd card  and usb0   image is     IOT2050_Example_Image_V1.0.2.img，download from siemens。

image file is  1.78GB  1,913,308,160 byte

OK, this clearly indicates that the eMMC does not contain anything bootable. You will have to recover from an external medium - but only one at a time.

Try plugging in the SD card with the example image first. If that card triggers that "uuid conflict" message of the boot loader, you will have to look for a different image, thus different partition UUIDs (e.g. on https://github.com/siemens/meta-iot2050/actions/runs/1028895431#artifacts).

I download the image and now iot2050 boot form emmc ok

thank you
