pncconf Mesa 5i25t_7i77_7i74

Hello, I have described the firmware of the 5i25t using mesaflash with bin file 5i25t_7i77_7174. When LinuxCNC starts, these are also present as pins in the Hal configuration.

Now I would like to create a configuration via pncconf.

I need 4 axes + spindle including encoder analog output and PWM generators

Unfortunately, the 5i25t is also found for me on Discovered Device, but I cannot activate any PWM generators. There is also the 7i77 I/O (SS#0) tab, but there are only TB7 and TB8. But I need TB5 for configuration

Is there a way to store the configuration in the lib/firmware/hm2 directory?
Does anyone have this firmware or the corresponding pin file?

Can the configuration even be carried out like this or do I have to use the HAL. edit manually.

It would also be necessary to configure the 7i74 connected to P2 (5i25t) or the 7i70 and 7i71 via pncconf.

Thank you very much for tips

Not sure why discover does not work (and create the 7I77 ss1 tab) ,
as it would have been  probably the best way. I don't think there
is any advantage to using  pin files as that is basically just doing
by hand what discover does automatically.

You may have to create a plain 7I77 configuration and then add the 7I70,7I71
pins yourself.

Thank you for the info.

That means I should use the discovered version and then finish the configuration in pncconf with the generated pins.

Then create an extra Hal file for the two cards 7i70 and 7171 in the Hal or?

Unfortunately, the following error occurs according to the attachment:

I would just create a 5i25 with one 7I77 config (and not use the discover option)

You can try this
forum.linuxcnc.org/39-pncconf/52554-disc...n-unlisted-mesa-fpga
or download the config files from here to compare
forum.linuxcnc.org/30-cnc-machines/31792...-01-retrofit?start=0
Please beware that this config uses serial absolute encoders, so not directly usable for normal encoders, and feedback goes to 7i74, not to 7i77 as usual.
Or this has normal encoders but uses a 7i92 instead of 5i25/6i25
