Please try to add IMAGE_INSTALL_append = " firmware-imx firmware-imx-sdma " into local.conf.

First thanks for your reply.But I compile the kernel directly,then hang on ubuntu18.04 rootfs.I compile the kernel through bitbake in the yocto project.The operation steps are as follows：

MACHINE=imx8mqevk DISTRO=fsl-imx-xwayland source ./fsl-setup-release.sh -b bld-xwayland/

bitbake -c compile -f -v linux-imx

bitbake linux-imx -c compile_kernelmodules -f -v

bitbake -c deploy -f -v linux-imx

then Replace the previous kernel with the generated kernel，mount Ubuntu18.04 rootfs。

please give me some advise,thanks!

Hi gao bo:

Have you solved this problem?

I got the same error when I used the serial port .

@Victor Linnik

Is there any solution? I have checked the firmware as the same above.

Thanks.
