pcie print error .can't insmod pcie device driver

backgroud:
1.board:tx2 jetpack3.3 xilinx v6
request.We use xilinx’s DMA Subsystem for PCI Express communication with tx2
questions:
1.pcie bus report same error and then i cant’t load my pcie device driver.
the error log image is add to attachment
2.Data cannot be effectively written to memory.
Only part of the data is written to memory, All the data with a value of 0 below failed to be written

Hi,
As I see so many physical layer errors, Can you please your setup once and see if there are any loose cables connected?
Also, can you please share the output of ‘sudo lspci -vvvv’?

1、I first turn on xilinx, wait a few seconds, then turn on tx2, giving TX2 enough boot time,physical layer error disappeared.Do I need to modify boot? add a delay?

2.I’m very sorry. I used the wrong title.pcie cannot be effectively written to memory,that’s the most important question.All the data with a value of 0 is failed to be written in memory.can you give me some advice? thank you very much

Since I see “Mem+ BusMaster+”, which means, the endpoint is set with BAR windows enabled and also Bus Mastering enabled, I don’t see any reason why writes are not working. This may be looked into from FPGA point of view. If possible, please connect it to an x86 system and see if you don’t observe the issue there (in which case we’ll debug more from Tegra side). At this point, it looks like FPGA configuration issue.

It’s the driver’s fault.thank you very much
