The SDMA firmware does not load automatically. I can find the /lib/firmware/imx/sdma/sdma-imx7d.bin and the dts points to the exact location.
The udev script needs to be implemented to load the firmware seperately which is executed after the default timeout of 60 secs. Am I missing any config in kernel? I could not see the same issue with iMX8MM EVK eval kit with IMX image with 4.14.

Hi Igor,
The issue is actually with FW_USER_HELPER_FALLBACK is enabled in kernel config. And i also made the imx-sdma as module. Thanks

Hi Igor,
Let me try this. But we are facing similar issue with all firmware loading. We need to write a separate udev to load them/ Does FW_HELPER_FALLBACK is needed
