I have connected an E9260 (Polaris 11 based) to a mini-PCIe slot on my NXP LS1012ARDB.

The GPU is seen, all the BARs are correctly assigned (but there's not enough PCIe memory space for the big BARs).

When I try to load the amdgpu module, I can't get the driver to enable the acceleration (the scratch register check fails).

The E9260 is connected to a PCIe x1 (Gen2) slot.

Anyone have an idea on where to look or how to fix this? This is a test-bed before we get an LS1046ARDB with quad core A72's.

Any help would be appreciated,
