imx8mq evk sdma firmware not ready?

[gaobo]

kernel：4.14.78

rootfs：Ubuntu18.04

machine：imx8mq-evk

Before that, I used the yocto project provided by NXP to compile the image.After burning it to the development board, all peripheral functions can be used.But now I use Ubuntu 18.04 file system to replace the file system in NXP demo, resulting in Bluetooth and sound card problems。（ imx-sdma 30bd0000.sdma: sdma firmware not ready!）

I don't think it's a driver problem, but I'm not sure what's wrong.

please give me some advise,thanks!
