Why Mesa 5i20 does not start?

I already changed the cables. nothing changed.
Now I will change two boards 5i20.

Here are configs.
LinuxCNC is 2.7.5

The outputs are close to what is expected with those configs

Based on the HAL file, I certainly I would expect GPIO 65 and 67 to be stuck on as you found

( Because 7I37 outputs are active low, if you enable FPGA GPIO outputs without setting the invert attribute,
the 7I37 output will be enabled as soon as LinuxCNC starts up)

If any 7I37 outputs are on when LinuxCNC is _not_ running, that suggests a FPGA fault

Why?

And setp ...065.out 1 or 0 does not make anything. These keys are just in open state.

are any GPIO pins low when LinuxCNC is not running?

No, only then LinuxCNC starts.

Anyway, I can't change output at 64-71 or 40-47 pins.
I tried open_drain too.
No luck.

On the other machine, I have not been able to obtain from the mesa 7i37 any outputs. Instead, I set card for LPT port. And it worked.

Why 65 and 67? Where did you get information?

No, only then LinuxCNC starts.

This strongly suggests that the problem is configuration, bitfile or OS/PC related, not a bad 5I20

What PC hardware, linuxCNC version, OS , and md5sum of svst8_4.bit do you have?

Why 65 and 67? Where did you get information?

They are not set in hal file, therefore will start up at a 0 level, turning the 7I37 outputs on as soon
as they are set to is_output

Why 69 and 71 are OFF?
