Raspberry Pi 4 & MESA 7i92

I'll continue to show my ignorance as now I am trying to install the 7i92 bit file for the g540x2d and receive the following message

.pi@cnc:~ $ mesaflash --addr 10.10.10.10 --device 7I92 --write G540X2D.BIT
Can't find file G540X2D.BIT

Is there a special process for installing the bit files as this does not seem clear in the HOSTMOT2 documentation?

Thank you

You would need to download the 7i92.zip file from mesa, unzip it and run the mesaflash command from the directory containing the appropriate bit file

Thank you but no joy. I did navigate to the folder with the BIT file and ran mesa flash. Still no file found.

pi@cnc:~/emc/src/mesaflash/7i92/configs/hostmot2 $ mesaflash --addr 10.10.10.10 --device 7I92 --write G540X2D.BIT
Can't find file G540X2D.BIT

Any advice appreciated-

In linux file name case is significant

Thank you, I noticed the case difference after I submitted my previous note. It appears to have loaded successfully/ Thanks again for the help-

You must power cycle the hardware or use the --reload command to load a new firmware.

Hi PCW

How can I install mesaflash on my Rpi3?
I surf the web but there is no relevant info about it.

sudo apt-get install mesaflash seems not to be on Rpi3 packages.
Maybe do I have to install it from source?

Any info is welcome.
Thanks in advance.

Yes, you can build from source:

github.com/jethornton/mesaflash

Many thanks PCW!

I figured it out and after some searches I finally found this link:

github.com/micges/mesaflash (I posted just in case)

I could build it fine. When I run the command it states:

Mesaflash version 3.3.0~pre (built on Feb 8 2020 14:20:13 with libpci 3.5.2)
Configuration and diagnostic tool for Mesa Electronics PCI(E)/ETH/EPP/USB boards
(C) 2013-2015 Michael Geszkiewicz (contact: micges@wp.pl)

I suppose it will work fine.

And, did it work fine on the RPi3?

Well... maybe I am a newbie in Mesa card matters, but AFAIK the Mesa docs are very poor and sometimes wrong.

This command from the 7c81 manual is wrong:
./mesaflash --device 7c81 --addr /dev/spidev0.0 --write 7c81_5abobx2d.bit

After contact Mesa Electronics a guy told me that it is wrong. I have to try this:
./mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid
But this command does not flash the firmware on the board as the manual states, it just query the default board configuration I think.

Is there any tutorial to fully configure a Mesa 7c81 for LinuxCNC?

Thanks!
