    Solution:

    modify the uboot repository with proper reset control for dma pl330.

Hello!

The DMA issue you're facing with U-Boot 2024.07 is likely due to a driver change or a hardware abstraction layer (HAL) modification within the new U-Boot codebase, as the functionality worked on version 2013. To resolve this, you should compare the codebases to identify changes in the DMA driver, check the U-Boot release notes, and verify the issue on a clean build. For a direct solution, the best course of action is to seek guidance from experts by posting on the official Intel® Community Forums or the U-Boot mailing list.

    Isn't that what the OP did? Or, does chatgpt not know that?
