Pressbrake CNC Control Setup Questions

You can create a 7I92/7I77 configuration with pncconf and use it as a guide/example to
make 7I77 related modifications to your 7I97 configuration files.

i can't detect the 7i77d connected to it. 
 

This might be because there is no field power connected to the 7i77.

Right, field power, 5V power and the correct firmware
(7i92t_7i77x2d.bin) would be needed to detect the 7I77

Yes this is exactly my idea. Use pncconf to generate something that can serve as a base to adapt the code present here which looks marvelous.
I plugged 5v to 7i77d and to 7i92tm through the 5v 0v connector (2pins connector), and also tried with both cable switches up in 7i92tm, and the 7i77 power switch to the left, and no tb1 power to 7i77, and it also lights up correctly, But no connection.

I'm using the original ribbon cable to connect from the black connector on the 7i92t to the 7i77.

I also pasted 7i92t_7i77x2d.bin in /lib/firmware/hm2 with the terminal cp command... but no new firmware appears in PNC selector, discovery still only finds 1 board.. although it is powered on through the ribbon cable.

should i do something else to be able to detect the 7i77?
I discovered it with 7i92t board name and 10.10.10.10 ip. Should i use other board name? Or do something else with the bin file besides just pasting it in the hm2 folder?

Yes, you need to write the firmware file to the 7I92TM:

mesaflash --device 7i92t --addr 10.10.10.10 --write 7i92t_7i77x2d.bin --reload

Thank you. I didn’t know i had to execute the script somehow. I finally got to the take the card in the readhmid and the discovery, but i still can’t attribute pins to the 7i77, although it appears as a non-selectable board.

Should i attribute all pins now through manual hal programming? Wouldn’t it appear as a board tab like tb1, tb2 etc ?
