Looks like you have empty PARTUUID in the kernel command line. Which wks
file do you use for this image? Which layers? Can you show your
bootloader config?
Please append a correct "root=" boot option; here are the available
partitions:

Dear Yocto Team Members，
I tried to dd *.wic to nand flash but always got kernel panic, it can
not find rootfs
when I dd the same file to sd card, it worked.
>from the bootloader command prompt, you may need to change the root
kernel parameter and point to the device where the filesystem resides.
I copy only *.wic file to usb drive n dd it.
Do I need the whole directory of images for dd? or I need hddimg?

Riko
