pncconfig error

Hello, I am using a 4 stepper motor machine and the mesa 6i25 card with a 7i75 breakout card and the gecko drivers used are the G214V. I wanted to do the pncconf wizard to configure my mesa card and I chose the 7i76*2 firmware as I have to connect the step, dir,fullstep, enable, error of each driver... but I get the following error. Can someone help me?

Can you post your hal/ini files?

hello, here it is.

What firmware is loaded on the 5I25?

what does

sudo mesaflash --device 5i25 --readhmid

report?

How is the 7i76 powered ?

I get mesaflash: command not found

maybe is it because I am using ubuntu? I do bash LaunchCNC.sh to launch either pncconf or stepconf.

You may need to install mesaflash on your system

github.com/LinuxCNC/mesaflash

Bottom of page has install instructions

thank you, this is what i get when i do mesaflash:

OK that's 7I77 firmware

For a 7I75 I would probably choose firmware with stepgens but no SSerial like 5i25_g540x2.bit

I didn't get,so which firmware shall I chose in the config?
