I’m going to delete your post in the other thread.  Double posting is discouraged and you’ve made progress here.

Did you do a package install?  If so, when the buildbot is done building chris’ changes, you’ll be able to update (should be good now).

in a terminal window, type:
sudo apt update 

when that is done type:
sudo apt dist-upgrade 

your linuxcnc should be updated.  No reason to redo the OS install :)

Commenting out hm2_5i25.0.dpll.01.timer-us gets my setup to run, how can i fix this so this component i am commenting out works?
Everytime i run pncconfig i have to edit this, just wondering if commenting this out could cause issues for me later?

No issues with deleting or comenting out that line, as far as i can recal.
It just means the DPLL timer is not in use.

Today I had same error trying to use pncconfig and a 6i25 with 7i76 card.

"parameter or pin 'hm2_5i25.0.dpll.01.timer-us' not found"

After uncommenting the line in the hal "setp [HMOT](CARD0).dpll.01.timer-us -50" as suggested.

another error showed up

"./my_linuxCNC_machine.hal:22: parameter or pin 'hm2_5i25.0.stepgen.timer-number' not found "

mentioning the timer number I just uncommented the next line in the hal file

# setp [HMOT](CARD0).dpll.01.timer-number 1"

Then the Axis UI started and I could do the first moves. So this thread helped me to get up and running.

Is that any problem? Or is that just a glitch in the pncconf sofware?

p.s.obviously 6i25 card is treated as 5i25, and all the names are 5i25 the system works like this.

Yes, pncconf assumes that the firmware includes a DPLL but most PCI configs do not.

One simple solution if you still want to change things with pncconf
is to use firmware that includes a DPLL:

Thank you for reply.

I understand I should change the bitfile on the 6i25, is that correct?

Is that done using mesaflash software? Have to look into that.

Yes and yes.
Although you should make sure the 5i25 and 6i25 use the same firmware.

I do not really know what am I doing (yet again :-) , there is a pattern )

I copied the 5i25_7i76.bit file into the /bin folder
Then typed

mesaflash --device 6i25 --readhmid there was an error message no device found, so I tried
mesaflash --device 5i25 --readhmid, a list of names and pin functions shows up.

Then typed:

mesaflash --device 5i25 --write 5i25_7i76x2.bit

Some messages appear, finally it asked me to power cycle or use reload.

type:

mesaflash --device 5i25 --reload

Then I tried to uncomment the lines with dpll timer back in the hal file.

Result: machine starts.

Was that correct?

Dear all,

I just did a fresh install of 2.9.1, using "www.linuxcnc.org/iso/linuxcnc_2.9.1-amd64.hybrid.iso" from "linuxcnc.org/docs/html/getting-started/getting-linuxcnc.html" followed by a setup with pncconf with the exact same settings as my previous working 2.8.4 setup.
At startup od linuxcnc I unexpectedly get this error "parameter or pin 'hm2_5i25.0.dpll.01.timer-us' not found"

Anyone who has a clue how to solve this?

Any help is very much appreciated :)
