Thanks Wolfgang, Per your suggestion, we tried setting the delay (and observed a delay), but the outcome did not change. The BIST still got set to fail and caused the board to become unresponsive, and thus Linux fails the detection later. FWIW, we've tried both with and without switches in between with no change in the behavior. We observe the transactions on a lecroy pcie analyzer. I suppose one question that lingers in my mind is why does u-boot do anything other than just configure the IO/MEM bars? Is there some specific reason it is touching the BIST controls? If I could understand the reason for this, I might be able to do some debug and at least determine whether I need to change u-boot, Linux, or both. Thanks so much, Ayman _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
