Hello,

just got a 7i92 for the first time. I used only 6i25 so far with a 7i77 and it was a bundle pre-programmed.

Do I need a special 7i92 firmware to operate with the 7i76 ? If yes, where do i get it ?

Thanks for help.

You should check with mesaflash for what is already in it,

mesaflash --device 7I92 --addr 10.10.10.10 --readhmid

That will show the pins for the existing firmware.
Go to mesanet.com, choose "anything io" or similar on the left side menu, find the 7i92 and there is a link to a zip file with all the firmwares for it.

13     33   IOPort       None

My 7i92 is a M version with a DB25 connectore on P2.

Here above, when I see that there is no IO connections on P1 and many IO connections for steppers on P2 , I would say that the firmware on this 7i92M is set for Steppers so for a 7i76.

But I don't read anything crystal clear that this 7i92 firmware is for 7i76. Am I correct/wrong ?

Thanks for your insight.

Yes that looks like it is for 7i76 on P2 so just plug it in and power it up.
Be sure to check the jumpers and read the manuals for the cards Before powering up.

t is always a best advice to flash the newest avalable
7i76x2 bit file

mesaflash --device 7i92 --addr 10.10.10.10 --write yourbitfile
mesaflash --device 7i92 --addr 10.10.10.10 --reload
repower
mesaflash --device 7i92 --addr 10.10.10.10 --readhmid > test.pin

Note that you do not need to power cycle the 7I92 if you use the reload command, the reload command does the same thing
(reload FPGA from Flash memory)
