7i43 GPIO Configuration Error

New EMC user here, I'm in the middle of converting an old Milltronics Partner II that had a dead controller. I'm using the Mesa 7i43(200k) w/ the 7i33 PWM servo card and the 7i37 I/O card. I've installed the live cd w/ the latest emc version and all of that is working just fine.

I can read the encoders in emc and then jog the servos around but I can't seem to get the GPIO working. If I set a pin as output emc won't load and I get the following error:

Debug file information:
mill.hal:75: parameter or pin 'hm2_7i43.0.gpio.017.is_output' not found
5242
PID TTY STAT TIME COMMAND
Stopping realtime threads
Unloading hal components

(Full file attached to msg)

In addition to that I can't seem to see any change on input pins when I try to view them in the Hal config. I'm lost as to where to proceed. I was amazed how easy it was to get the servos working and the mesa card talking to EMC. Can't wait to get the GPIO working so I can finish up and start making chips soon.

Thanks for the help,

Forgot to post my hal and ini file.

GPIO17 is very unlikely to be available in a servo config, as most servo configs put the servo interface (PWM and encoders) on the first connector = I/O 0..23 = P4
probably I/O 24..47 (P3) will be GPIO so for a 7I37, GPIO40 through 47 will be the outputs

This is most likely a problem with pncconf.
You are using EMC 2.4.6 ?
There is a bug about component numbering for the 7i43.
The fix has not been released yet unfortunately.
I'll try to think of a work around - plus try to remember what exactly the problem was.

this is the commit for the fix so sounds like your problem:

"fix 7i43 firmware array - connectors not in right order

I failed to see the connector numerical order is not the same
as the components logical order. So setting gpio on connector3
would actually be setting it on connector 4. If there was
enough special components to span both connectors their
numbering would be wrong too."

things you could do;

- hand edit the files you have. ( not fun but you learn lots )

- download the latest bugfixed version from EMC's buildbot.
buildbot.linuxcnc.org/
This would replace your released version of EMC with the buildbots version.
buildbot makes its versions from the repository that includes the latest bug fixes.
You would get the latest bug fixes almost as soon as they are fixed.
I like this one.

- you could copy a new version of pncconf over the old ( its found at /usr/bin/pncconf )
you need sudo to do this.
this would be overwritten on the next release but then would be fixed anyways.

no idea when the next release will be. ( I've asked )

Thanks for the help that worked. I admit I took the easy route and used the buildbot to get the latest version. It was nice to have a working test panel too! Now I can move on to other things, getting closer to making chips!

Oops the test panel is not supposed to be available.
I had the seemingly unfixable problem that it would always work the first time but not after that until PNconf was reloaded.
and tests wouldn't work until the command 'halrun -U' was run in terminal.

Is this true for you too?
I've wanted that test panel to work for a very long time!

It worked w/out running any other commands. I will have to try going back to it twice w/out restarting pnconf.
