Under Resources settings an error message ' This device isn´t using any resources because it has a problem.' appears and no memory mapped or interrupt setting.

Question

No memory mapped or interrupt set.(Resources Settings)

I developed a driver (LINUX and Windows) and the Verilog Code for the PCI Card and everything is ok when running on LINUX.

In Windows I installed the driver and everything was ok about installation without any error code but

Why the OS write zeroes to base address register BAR0 (offset 0x10) and BAR1 (offset 0x14) after booting?

BAR at Offset 0x00000010 is an I/O address.

BAR at Offset 0x00000014 is a memory-mapped address.

DriverEntry completed successfully.

The driver were developed writing a Windows Driver Model Driver.

Answer 1

After BIOS/UEFI update Base address for Bar0 and Bar1 were configured correctly as can be seen below:

C:\Users\admin\Desktop\pcinew\pciutils-3.5.5-win32>lspci -x -s 04:01.0

04:01.0 System peripheral: Device 5105:0101 (rev 01)

00: 05 51 01 01 03 00 00 04 01 00 80 08 00 00 00 00

10: 01 d0 00 00 00 00 c0 f7 00 00 00 00 00 00 00 00

20: 00 00 00 00 00 00 00 00 00 00 00 00 05 51 01 01

30: 00 00 00 00 00 00 00 00 00 00 00 00 0b 01 00 00

The PCI card can communicate but no memory mapped or interrupt set are presented in Resources Settings tab.
