For some reason BAR is not allocated for the device. Check PCIe subsystem logs during PCIe enumeration at boot.

Dear Manikanta,

i became know, my PCIe Capture card is configured two mode by it’s Firmware. one is for x86 system, and the other is for Arm(Embedded) system.

Now my PCIe Capture card works normally after installing a F/W for Arm system.

Thanks,
