hm2dpll, pin hm2_XiXX.N.encoder.MM.timer-num does not exist.

How does one configure hm2dpll for encoders?

This hal fragment is throwing the error:

Is this maybe not working for muxed encoders?

What configuration are you using?
( and how many encoders have you enabled )

OK there does seem to be a bug in the encoder DPLL setup
I think its possibly a firmware bug, I will look into it

Note that the proper pin would be:

hm2_7i80.0.encoder.timer-number


EDIT:
it looks like most 7i80 bitfiles were made before encoder timestamps were added to the firmware
so they likely need to be built from source to get encoder timestamps working

Component Pins:
Owner Type Dir Value Name
23 s32 IN -1 hm2_7i76e.0.encoder.timer-number

(I had to rebuild the bitfile to get this)

I am building from source.

A git clone of master from github.com/LinuxCNC/hostmot2-firmware

Thats at least a year or two out of date
i would fetch the source from Mesa and re-build

PCW wrote:

How?

Download the 7i80.zip file from Mesa
The complete hm2 source is in configs/hostmot2/source

Hmm...

Somehow the zipfile is incomplete.

Replacing the 'src' directory of the git clone (where there is a makefile for building a debian package) with the 'configs/hostmot2/source' directory from 7i80.zip ends with:

I am at a loss to know how to correctly modify the makefile containing:

Which new vhd file takes the place of the missing d8o8.vhd ?

You could extract the current source list from the appropriate project file (or just use the project file as is)
