Agilex 5 - PCIe

Hi,

Thank you for your response.

I downloaded your project and ran it on my device.

I connected the Dev-Kit to the motherboard, uploaded the program, but unfortunately, Windows does not detect any device – the same issue occurs on Linux, no device is detected.

I also have a devkit from Arrow (Arrow AXE5-Eagle FPGA Dev Kit). Using the same project – only changing the pin assignments – Windows detected the connected device, and so did Linux.

According to the documentation (GTS AXI Streaming Intel® FPGA IP for PCI Express Design Example User Guide), I installed the driver:

I ran the test program: ./software/user/example – and got the following results:

Even when performing individual read and write operations, the result is the same.

From the Ubuntu side, I checked:

robert@robert-Z590:~$ lspci -d 1172:
02:00.0 Unassigned class [ff00]: Altera Corporation Device 0000 (rev 01)

LnkCap:	Port #1, Speed 8GT/s, Width x4, ASPM L0s L1, Exit Latency L0s unlimited, L1 unlimited
		ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp+
		
LnkSta:	Speed 8GT/s (ok), Width x4 (ok)
		TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-

So the link between the device and the computer exists – but there is still a problem with reading and writing.

I checked the signal assignments according to the documentation (GTS AXI Streaming Intel® FPGA IP for PCI Express User Guide) – all pins match the values from the table.

I enabled the debug toolkit and got the following results:

Do you have any idea where the issue or error might be?
