Crossflash ConnectX-4LX to ConnectX-4

[efschu3]

Edit:

Destroyed the Card. So "we" learned you cannot crossflash Cx-4LX to CX-4



Any chances I can crossflash a ConnectX-4LX to ConnectX-4

mstflint -d 01:00.0 -i fw-ConnectX4-rel-12_18_2000-MCX455A-ECA_Ax-FlexBoot-3.5.110.bin -allow_psid_change burn
Done.
    Current FW version on flash:  14.23.1020
    New FW version:               12.18.2000

    Note: The new FW version is older than the current FW version on flash.

Do you want to continue ? (y/n) [n] : y


    You are about to replace current PSID on flash - "FB_2510111032" with a different PSID - "MT_2180110032".
    Note: It is highly recommended not to change the PSID.

Burning FW image without signatures - OK
Restoring signature                     - OK
-I- To load new FW run mstfwreset or reboot machine.

the "--no_devid_check" seems to burn it, let's see how it works (fingers crossed)

There is parameter that bypasses all checks, I think it was "-b".

But be carefull because it can "brick" the card when used with a wrong firmware. Before you try to crossflash make sure that your card has the pins for recovering the card.

Aren't LX cards Ethernet only? If they are like CX3-EN you won't be able to reflash them to VPI.
You should probably reflash to Firmware for ConnectX®-4 Lx EN if you absolutely need it.

Actual I "need" the 100Gb from "normal" CX4. CX4Lx goes only to 50Gb.

Destroyed the Card.

Try the recovery process by shorting the pins

 

[efschu3]

If you can tell me which one it is?

Or if you could tell what's it called on a "normal" CX4 ?

Some Pictures of the Card:

In the last picture, upper left, we have a FNP jumper. Shorting the pins put the card in recovery mode being recognized as a memory device.
Just flash the correct firmware.

Tnx.

Yeah, will flash Back shiped Firmware.
