7i96 hm2: firmware contains unknown function gtag-195

Using Stretch image from download with PREEMPT RT and with Linuxcnc 2.7.14

On startup I get message
hm2: firmware contains unknown function (gtag-195)

Anyone knows anything about this?

Yes, the 7I96 requires LinuxCNC 2.8 for support of the SSR (isolated output) modules

Thanks , I just tried master and installed 2.9 so not getting that warning any more, Did not try the outputs yet.

What I am getting now is that somehow output step velocity has too much jitter. The motors stutter . This is stepper system and P is 1000 FF1 is 1 . I constantly have some following error and its going back and forth like untuned servo. It seems it has nothing with 7i96 but its from PID output or input

Can you post your hal/ini files? sounds like a setup error of some kind

No problem here they are

A couple of things

1.
addf hm2_[HOSTMOT2](BOARD).0.write servo-thread
should be the last addf (after the PID calculations)

2.
all lines like
setp pid.n.maxerror .0005
should be changed to
setp pid.n.maxerror .013
(or just commented out)

3. all lines like
net n-vel-cmd => pid.n.command-deriv
should be commented out

That seems to have fixed it !

Thanks Peter
