Do you have the right configuration defined in the device tree file.

Is this seen on TI EVM or on a custom board. If it is with custom board, please review changes carried out in the device tree file for your platform

This is on a custom borad, I check the configuration of device tree file, and our borad has early video in M4(IPU2), so we are assigning first 32 channels to Linux(A15), and last 32 channels to M4,

and we have configed the edma in infoadas tree.

&edma {
dma-requests = <32>;
};

Can you attach complete device configuration details with respect to EDMA

from the logs shared, we seem to be missing the hwmod definition for EDMA module

Hi @user6163292 ,

We haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
