Kernel driver for ACPI node load fail as Code 12 (0xC00000E5)

Question

Hi,

I am writing a kernel driver for an ACPI node.

I declared resource in ASL for this node as below:

    Device (TEST) 

    { 

        Name (\_HID, "ACPITEST")  // \_HID: Hardware ID 

        Name (ACRS, ResourceTemplate() { 

           Memory32Fixed (ReadWrite, 0xFE0B0000, 0x1000)

           IO (Decode16, 0x940, 0x940, 0, 0x01) 

        }) 

        Method (\_CRS, 0, Serialized) 

        { 

            Return (ACRS) 

        } 

    }

I created a KMDF driver based on the VS2022 template. I only modifed the INF to include the ACPI Hardware ID.

    %TestDriver.DeviceDesc%=TestDriver\_Device, ACPI\ACPITEST ; TODO: edit hw-id

When I load the driver, the device cannot start successfully, while the resource seems set correctly.

Device status: Code 12

Resource settings meet my ASL code.

Driver status: 0xC00000E5

Any idea is appreciated.

Thanks.
