Unable to retrieve required Device PCIe ID

[PrideIsLife]

Hi,

I have a PCIe connection issue with my SCREAMER PCIE SQUIRREL.
I have tried connecting the card to two different host PCs :

• one high-end AMD (Ryzen 9 7950X, 32 Go DDR5 5600 MHz, ASUS TUF GAMING X670E-PLUS)
• one low-end INTEL (Core i5-4460, 8 Go 1600 MHz, Asus H81I-PLUS)

but end-up having the same issue for both setups :

DEVICE: FPGA: ERROR: Unable to retrieve required Device PCIe ID [4,v4.11,0000]
PCILEECH: Failed to connect to the device.

On both setup the card was connected to a PCIE x16 slot.
I also tested the connection on two different client computers but that didn't help.

The card LEDs has normal "behaviors".

DEVICE: FPGA: ERROR: Unable to retrieve required Device PCIe ID [4,v4.11,0000]
MemProcFS: Failed to connect to memory acquisition device.

Do you have any tips on how to debug this ?

USB communication with the device is working.

There is no PCIe connection to the device though, or it haven't been configured.

The PCIe config space looks overly strange, i.e. vendor/device id = 0000:0000.

This is most likely an error with "custom firmware". Flash the default bitstream I have here on my GIthub site in the releases section.
