Need help to wire and config Mesa 7i92TM

So, the BoB has the DB25 numbers.
And the Mesaflash output links the DB25 numbers to stepgen and GPIO numbers.

(So, for example, stepgen.0.step is on DB25 pin 2. pwmgen.0.out is on DB25 pin 14.)

The numbers in Pncconf are the function numbers, eg stepgen.0, pwmgen.0, or for pins where the function is not used, the GPIO number to match the HAL file pin names.
hm2_7i92.0.gpio.016 for example.

This thread might provide some additional information:

Looking at Screenshot_2023-05-27_15-25-11_2023-06-22.png

The first pin is an unused input, being set up as GPIO, and is GPIO 000, and would appear in HAL as hm2_7i72.0.gpio.0000

The next pin is being set up as a PWM. It is pwm number 0, and would be controlled in HAL by the pins hm2_7i92.0.pwmgen.00.enable, .value etc.

The next pin is a stepgen, number 0, and would be controlled by h2_7i92.0stepgen.0.position (etc)

And then there is gpio.004, then the DIR pin for stepgen.0 (not numbered, I am not sure why), then stepgen.4 step and so on.

But, all you need to do in that screen is decide what you want to use each stepgen and PWM for. Then you work out which pins they are on the BoB from the mesaflash output.
