imx8mq evk sdma firmware not ready?

Question asked by gao bo on Nov 13, 2019





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!
