Unable to generate 'Unsupported Request Error'

Jump to solution

I have setup with EP card (PCIe complinace customised Exerciser card) connected over PCIe slot at Server platform.

I want to generate and identify UR at Root port side. Looks liek I'm not able to generate and detect UR.

Here are the details:

EP side:

- BAR0 base address mapped to 8750_0000 (at 10h offset)

RP side:

- BAR0 base address mapped to 87f0_0000 (at 10h offset)

- Meory Base Address mapped to 8400_0000 (at 20h offset)

- Memory limit 85f0_0000

I have enabled all registers responsible for error reporting and genertaing at both the ends.

AT what address I should do read operation so that RP should generate UR or should receive UR?

you  can try to  generate a TLP ,a memory read for example, with poisoned bit set 

then you can check Device Status
