Flash OEM HPE Mellanox ConnectX-4 VPI with mellanox firmware

I need help flashing an HPE InfiniBand EDR/Ethernet 100Gb 2-port 840QSFP28 Adapter 825111-B21 (Mellanox P/N: MCX456A-ECAT) with latest Mellanox firmware. I know this is void warranty, but HPE does not have the latest firmware available.


You can update firmware with “allow_psid_change” option.

Have a nice day!

Hi. Option -allow_psid_change worked. Only seen connectx-2 and 3 examples online, had too double check first. Thanks for the help.
