Re: [meta-freescale] How to get firmware-imx for imx8mm evk into sdcard image? I'm getting firmware loading errors for sdma-imx7d.bin etc.

Hate to bring up an old thread again but I'm back to trying to pair down my
image size and trying to use core-image-minimal and having issues with
firmware-imx-sdma-imx7d & sdma-imx7d.bin

If I just build imx-sdma as a kernel module do I even need to worry about
sdma-imx7d.bin being in the rootfs?
