This question is regarding a X550-BT2 controller design - not an add-in card.
This is our design and has not been reviewed by Intel.
We used the following Intel documentation:
Intel Ethernet Controller X550 Datasheet Revision 2.2 July 2017 333369-04
Intel Ethernet Controller X550 Specification Update Revision 2.3 July 2017 333717-004
X550-BT2 Reference Design 333902-004 Rev 1.9 10/05/15
X550-BT2/X540/I350-BT2 Reference Design 333900-001 Rev 1.9 10/05/15
My question is regarding source for the NVM and the tools to update it. This is not a hardware question or design specific.
