7i80db16 7i85s only one stepgen out was created by billykid
I had a 7i80 with a 7i85s and a 7i37 working with 3 stepgen, I tried reconnecting it and only a step dir signal comes out of the y-axis and that's it. I loaded the firmware 7i80db_16_7i85sx3d.bit. I don't understand what could have happened, I put it away and all three axes worked.

What does mesaflash --readhmid report when  the 7i80db_16_7i85sx3d.bit firmware is loaded?

Here is the file, you can see that  stepgen 03  has only dir , I don't understand why I put aside this combination: 7i80-7i85s-7i37 went 3 motors in step dir. I only need it as a transition because then I will switch to the 7i97t in analog, but for now I wanted to use step dir for 4 motors without any encoder or anything else.
in practice only the stepgen 3 one doesn't work

Anyway, I solved it with 7i80db_16_7i85sx2d.bit and replacing stepgen00 with stepgen04, now everything works. I'll leave it like this, as I'll switch the 7i97t to analog soon. Thanks!
