MESA 5I25 with 7I52S and 7I37-TA possible?

So obviously new to MESA and linuxcnc.... thought I was a electronics tech that would have no issues with this ... but wow a little over my head!

I have a 5i25 pci card with a 7i52 to provide 6 axis step/dir (upgradeable to PWM servo in the future) and 7i37-TA for IO (coolant, tool changer etc).

I have linuxcnc 2.8 on mint, mesaflash installed and 5i24_25_svst6_6_7i52s.bit successfully flashed with
sudo ./mesaflash --device 5i24 --write 5i24_25_svst6_6_7i52s.bit

Rebooted and pncconf does not recognize or see a 5i24? Not sure where to go next. Any help is appreciated.

Thks

I dont think pncconf knows about the 5I24
so the closest you could get for a simple step/dir system
would be to specify a 5I25 and say a G540

This will create the boilerplate hal/ini file that should be close
You will have to change the card name from 5I25 to 5I24
and figure out the GPIO bits for the 7I37

Awesome quick reply! But not really what I was hoping to hear!
I guess not really supported for linuxcnc? I should not have assumed just because they were in the "LinuxCNC Supported Boards" menu on the mesa store website.....

Im sure this is doable... just manually. Ill get there but may bug you for more details when I hit the next road block ;)

And a correction to my original post and title...... I have a 5i24-25 but I think you noticed that PCW

The 5I24 is fully supported by LinuxCNC, there is just no graphic configuration tool for
for creating starting hal/ini files. Note that even with a graphic configurator, most linuxCNC
users will need to hand edit hal/ini files.

Just now getting a chance to look at this.... 5i25+G540 in pncconf looks foreign to what I physically have.

I just tried the discovery option and appears successful? Displaying proper I/O connectors... should I proceed down this path or go back to the 5i25 config as you already suggested pncconf does not recognise a 5i24?

The discover option is experimental but worth a try

Note that the foreignness of the hardware is not really significant
to the hal and ini files. The only significant difference between a
5I25/G540 configuration and a 5I24/7I52S configuration will be
the actual GPIO pins used to the 7I37 (and the 5I25 vs 5i24 card name)
