7i97T -> 7i74 -> two 7i84U (no link) was created by Kuzma30
I am changing CNC system on milling machine with 3 analog axies drives.
I planning use such board 7i97T -> 7i74 -> two 7i84U.
I connected P2 of 7i97T with DB25 7i74, loaded 7i97_7i74D firmware
When I try run linuxcnc I see such logBut in firmware P2 pins configured as SSerial chanells. In log I see that this pins configured as IOPort.

Do the 7I84Us have both FieldA and FieldB power supplied?
Does the 7I74 have 5V power?
Does the 7I74 have 5V power?

I think I may have found the issue:
There's a bad 7i97t_7i74d.bit firmware file around
If your file is dated 2023, it's bad
The current one, fetch-able from Mesa's web store works.

You are right. Problem solved when I configure board and use external 24V voltage for VIN.
