Mesa Flash - Mesa 7i94.

Unsupported device???
Well, you might want to wait a bit for PCW ( Peter from Mesa ) to answer this as i do not have a 794 to test with.

sudo mesaflash --device 7i94 --addr 192.168.1.121 --write name_of_the_bitfile <<<this should be the actual name of a bitfile that is in that zip file, not name_of_the_bitfile

First check what bitfile you would need, then check if it already is in the 7i94, if not then flash it.

I've already sent Peter (Mesa) an email about this.

I will be using the SSD bitfile.

Thank you!

I just tried and it works for me:
peter@pcw-HP-EliteDesk-800-G1-USDT$ mesaflash --device 7i94 --addr 10.10.10.10 --readhmid
Configuration Name: HOSTMOT2

General configuration information:

BoardName : MESA7I94
FPGA Size: 9 KGates
FPGA Pins: 144
Number of IO Ports: 2
.......

Did you compile and install the mesaflash from

github.com/jethornton/mesaflash

Thats what I am using

It's working now!

I've just uninstalled and re-installed mesaflash ( github.com/jethornton/mesaflash/blob/master/README.md ).

Thank you for the support!

Glad its working , you probably were running the older version

To amplify on what tommylight was saying, do no write anything to the 7I94
other than a file with a name that starts with 7i94_ and ends in .bit

Hi PCW,

I've re-built the linuxcnc ( github.com/KurtJacobson/RF45-CNC/wiki/Bu...LinuxCNC-From-Source ) after replacing the hm2_eth.c and pins.c files in the directory: linuxcnc-dev/src/hal/drivers/mesa-hostmot2/

When I tried to compile (make) the 2.7 branch I had multiple undeclared errors generated by the pins.c file.

So, I tried the 2.8 branch and It also generated errors but they were all related to the undeclared definition "HHM2_GTAG_INMIX". Then, I opened the pins.c file and commented the lines of code which use this definition and it worked! Please find attached the modified pins.c file.

Then, after launching the linux cnc from the terminal I came across with the window "Confirm automatic update". It says I should update linux cnc.
I ignored this and I was getting errors: "the linux cnc was shutting down and cleaning up"

What linux CNC version should I be using with mesa i794?
Should I update linux cnc?


Best Regards,
Laura
