The unidirection DMA read only or write only of my PCIE NIC controller V5-based works fine .
However,if DMA read(from host--->ethernet port) is progress ,additional i send ping packet continuing from Host or client.the NIC will doesn't work.the send/receive is stoppped.
But,if DMA write(from ethernet --->host) is progress,additional i send ping packet continuing from Host or client. it still works fine.
who can provide any clue to debug the issue?
Probably someone with any information whatsoever about what hardware you're using, how it's wired up, what tools you're trying to implement this with, or what cores you're trying to work with. But who that would be is anyone's guess.
