Hi Stuart,

Steve’s 6200 didn’t train to x4 either, being either x1 or x2. Leif’s more meaty graphics card mostly locked things up, until after a reset and a reboot it was training to x2 2.5GT/s.

It was found out that UEFI PCIE training serdes routine requires an
update, as it shows instabilities with x4 graphic card, whereas it was
all fine on the same board with u-boot. Just for the sake of
verification, would it be possible, that you reflash your firmware to
use u-boot and check the card again? I hope to get the uefi patches in
the beginning of February.

Best regards,
Marcin
