Issue with transferring video frames through dma channel_1 in Jetson AGX Xavier board

Hi,

We have configured the Jetson AGX Xavier boards as PCI endpoint and root complex and tried to transfer video frames from endpoint to root complex using endpoint dma channels.

When we transferred video frames from endpoint using dma channel_0, it got streamed on the root complex without any issue but, when we tried to transfer video frames through dma channel_1, the stream got freeze on a frame after streaming for some time. when we try to stream again, we did not get any data from endpoint. This issue was not there, when we used dma channel_0. can you tell me, what may be the reason for this issue?
