From: Marcel Ziswiler <redacted> This avoids firmware load error and sysfs fallback reported as follows: [ 0.199448] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2 [ 0.199487] imx-sdma 302c0000.dma-controller: Falling back to sysfs fallback for: imx/sdma/sdma-imx7d.bin
unfortunately this isn't an explanation why this solve the issue. It looks like that the SDMA firmware is not available for the kernel. Build the driver as a module hide the issue and just load it if the rootfs is available. What makes you sure that the driver is not critical for other boards during boot? Best regards
