Should the HoneyComb LX2 PCIe slot be enabled and functional with the default image provided by SolidRun, or is it necessary to build a custom image or perform some other configuration? What would we expect to see from uboot and/or Linux (e.g. what is the logical PCIe slot number for the physical slot)? Using the latest available pre-built image (“lx2160acex7\_2000\_700\_3200\_8\_5\_2-2aefef2.img”, 3-Sep-2023), putting a PCIe card in the slot does not appear to be detected or usable.

Yes the device should still be detected. What card is plugged into what slot?
