Problem with 7i80db_16_7i76x2_7i77x2D

I have a 7i80db that I have flashed with the 7i80db_16_7i77x4.bit. This works perfect.

I shall add a toolchanger with a stepper motor and have tried stepgen in software, but it is to slow and I also prefer not to add the base thread, so I should make a try with the hardware stepgen.

I flashed the 7i80db with the 7i80db_16_7i76x2_7i77x2D.bit
After reconfiguring my hal-file, linuxcnc starts again without error.
My problem is that I don't get any signals from the input on the 7i77. I have 24V on INPUT-00 but it shows off in HalView.

Somthing is probably wrong with the config, but since linuxcnc starts and all pins I have used shows up in HalView, I don't understand what the problem is.

Any suggestons?

Are you using watch or halmeter to check the pins? ("show" only shows the state of the pin when its was selected)

If there is an issue it may be because that;s a pretty uncommon configuration
and uses 2 sserial modules so a driver bug is possible

I was using halshow - Watch tab. It normaly follows the actual stat of the input as far as I have seen.

Maybe a bug then.

Can you run mesaflash with the --readhmid option and post the results here?

When I run " mesaflash --device 7i80 --readhmid " I get " mesaflash: unrecognised option `--readhmid' "

I'm running mesaflash on a windows machine. There is a program in the utils catalog that is called readhmid.exe but nothing happens when I run that.

--Verify gives this report

fetch the latest mesaflash (for linux) with:

sudo apt-get install mesaflash

and try again

That was better.
Here is the output:

OK that looks kosher.
What does your config line that enables the sserial ports look like?

loadrt hm2_eth board_ip="192.168.1.121" config=" num_encoders=6 num_pwmgens=0 num_stepgens=1 sserial_port_1=000xxx"

I have tried sserial_port_1=000000 with same result.

Input is like "hm2_7i80.0.7i77.1.0.input-01"

You might try including the sserial config for both sserial port 0 and 1
