When I did fdisk -l here was what I got :

I boot from :
Disk /dev/mmcblk0: 14.6 GiB, 15640559616 bytes, 30547968 sectors
but I can't boot from : Disk /dev/mmcblk1 which is NAND flash chip.
Is there a partition problem here ? thanks
I saw something strange on NAND flash partition :
Disk /dev/mmcblk1boot1: 4 MiB, 4194304 bytes, 8192 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk /dev/mmcblk1boot0: 4 MiB, 4194304 bytes, 8192 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
I tried to fdisk it but can not, any other option for deleting it ?
Thanks

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

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
