Hi All
I use yocto repo sync (Linux 6.6.23_2.0.0)and bitbake imx-image-core then flash .wic(uuu) to imx8 evk that work fine.
but when rebuild the uboot and kernel (no changed any code ) and flash .wic(uuu) to imx8 evk that Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) occur?
The steps to recompile are as follows:
1.
Attached is the boot information.Thanks
Hi
Are you using imx8mq wevk or imx8mq evk(older)?
Best Regards

Hi Zhiming_Liu
The board is imx8mq evk.
The P/N is MCIMX8M-EVKB , and quick start guide document show i.MX 8M Quad Evalation Kit inside. Thanks.
Hi
The L6.6.23 support i.MX8MQ WEVK with NXP wifi, not older EVKB.
After only modifying sources/meta-imx/meta-imx-bsp/conf/machine/imx8mqevk.conf, the older EVK can boot normally.
MACHINEOVERRIDES =. "imx8mq-evk:"
require conf/machine/imx8mq-evk.conf

Hi Zhiming_Liu
After modified file and rebuilt the u-boot & kernel, the error still occurs.
Attached is the boot information.Thanks
Strangely, I built the .wic file this morning and boot successfully.
but in the second built(imx8mqevk.conf and other code no any changed )
the error occurs again.
my step is:
$bitbake -c cleanall imx-image-core
$ bitbake -c compile -f u-boot-imx
$ bitbake -c deploy -f u-boot-imx
$ bitbake -c compile -f linux-imx
$ bitbake -c deploy -f linux-imx
$ bitbake imx-image-core
Hi @Ichi_
Have you modified the uboot or linux source code? If yes, you can try to discard changes. Or you can try sd boot.
