trying to flash MCX515A-CCAT to firmware Rev 16.24.1000 in windows pe 10.0.17134

i have downloaded the WinMFT_x64_WinPE_4_13_0_104.zip for win PE64 and the firmware file

fw-connectx5-rel-16_24_1000-mcx515a-cca_ax-uefi-14.17.11-flexboot-3.5.603.bin

are there instructions specifically how to run this in winPE?

When i run the command “mst start” or “mst status” i receive this “-E- environment var MLNX_WINMFT not found!”

I am running into the same thing using Windows 10. Have added MLNX_WINMFT with a variable value of C:\Program Files\Mellanox\WinMFT\ as a system variable and a user variable and also to the PATH variable but still get the same error. Hope someone can help us both?

Well - I rebooted my PC and then it worked! Stephen Rice - looks like you would use the setx command to set environment variable sin WinPE. Here is a link https://superuser.com/questions/621484/setting-environment-variables-and-appending-to-system-wide-path-with-a-windows
