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.
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?
Regards,
Riko

from the bootloader command prompt, you may need to change the root
kernel parameter and point to the device where the filesystem resides.

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?

Is it related with linux-yocto kernel config ?
Please see attachment, thanks

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
I/O size (minimum/optimal): 512 bytes / 512 bytes
I tried to fdisk it but can not, any other option for deleting it ?
Thanks

Hi Riko,
Sorry for this confusion.
You can see used wks file

Sorry for the confusion. You can read about wic and wks in the
documentation:
To understand which wks file was used to build your .wic image you can
run this command: bitbake -e <your image> | grep ^WKS_FILE=
> what layers do you want to know?
all of them :)
Please, show me the output of 'cat conf/bblayers.conf'
> I was bitbaking core image minimal xfce.
looks like you're using meta-xfce layer.
> How can I see my bootloader config?
You can mount your boot partition and see it there. Something like this:
# kpartx -va ./tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic
add map loop2p1 (254:3): 0 46896 linear /dev/loop2 2048
add map loop2p2 (254:4): 0 49568 linear /dev/loop2 49152
# mount /dev/mapper/loop2p1 /mnt/
# cat /mnt/syslinux.cfg
PROMPT 0
TIMEOUT 0
ALLOWOPTIONS 1
SERIAL 0 115200
DEFAULT boot
LABEL boot
KERNEL /vmlinuz
APPEND label=boot root=/dev/mmcblk1p2 rootwait rootfstype=ext4
video=vesafb vga=0x318 console=tty0 console=ttyS0,115200n8
Note, that your image may have different bootloader.

I don't think so. It's about kernel build configuration.

I can tell you more after I can see .wks file you're using. So far I can
guess that you're using something similar to
scripts/lib/wic/canned-wks/directdisk.wks
which uses this or similar partitioning scheme:
part /boot --source bootimg-pcbios --ondisk sda --label boot --active --align 1024
part / --source rootfs --use-uuid --fstype=ext4 --label platform --align 1024
--use-uuid option means that kernel command line in bootloader
configuration file contains root=PARTUUID=<root partition UUID>. That
works for your USB drive (/dev/mmcblk0), but doesn't work for your NAND
for some reason.
There is a simple workaround for this issue(you can switch to using
device names instead of PARTUUID in .wks). However, it would be better to
investigate and fix this properly.
As I don't have a device to reproduce this I need your help.
We can either continue here or you can contact me(ed21) on #yocto freenode channel.
There I can help you faster I hope.

Ed
