Hello, Everyone. i bought imx8mp dev board(not official version) and success run sof.

the default sof version: 

Firmware info: version 1:5:0-cc5ba
 
kernel version: 5.4.70-2.3.0.
 
and i wanna to build the same sof version by myself.
 
at first i build xtensa-imx8m-elf by build tool
 
the i clone sof and `git reset --hard cc5ba`
 
of course, i build successful and get `sof-imx8m.ri`
 
i replace into board  but hang on kernel.

Hello lenghonglin,

I guess you have to build with extensa toolchain but this work on L5.10.72 BSP.
