In the process of uboot loading the kernel，dmesg log follow：
Causing Bluetooth and Audio Card not to work properly,
please tell me that how to solve it,thanks!!!
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!
Please make sure that you have right SDMA driver.
in dts,success config
