pls refer to this:

https://thesofproject.github.io/latest/getting_started/build-guide/build-from-scratch.html#

if you need the demo, try to choose this dtb:

"https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8mp-evk-sof-wm8960.dts?h=lf-5.10.y"

it seems that you don't use nxp board, you can check the logfile, where do your media mount? check dtb file there, I don't know how you download the images, and what media you use, for nxp board, after you building the bsp, you can find all of dtb files, you can download the specific dtb to the board or download wic images which includes all of dtb files
