USB errors while streaming via ehternet adapter

Scott Cloutier

Anyone have any idea what causes these messages; I am running DVSDK V2.10 and LSP 2.10 as well. These annoying messages come out of my console port.

Scott,

Do you see any error in frames received from camera ?

Not that I noticed. But these messages come up in groups. Is this an indication of a DMA conflict or something?

This shows thats rx endpoint interrupt arrived while DMA is busy in unloading the previous data in Rx FIFO. This looks to me a condition when DMA has just completed unloading the data and before DMA completion interrupt we get endpoint interrupt. this endpoint interrupt is not due to any error also as all error check are completed before this print.

I am facing a similar issue on DM365. Whenever this issue occurs we are observing a packet loss. Let me know if you have any inputs in overcoming this issue?

Thanks,

Sandeep
