Remapping the "Focus" button on Pyxis

I am trying to remap the "Focus" button on my PL mount Pyxis because for PL mount it's useless since PL lenses lack auto-focus. So it makes sense to have the button toggle "Focus Assist" on PL mount cameras.

I'm sure this is user error...

In the Menu/Settings/Setup "Set Function Button" page, I select "One Shot AF" set to toggle, I select "One Shot AF Parameter" to "Focus Assist" and I select/highlight "LCD" for "One Shot AF Parameter Displayed On"

I exit the menu and try to use the button (directly below the Iris button) to toggle Focus Assist and no go. I can manually choose focus assist from the LCD touch screen as a baseline for determining if focus assist is working with the "focus" toggle button.

What am I doing wrong here?

Thanks,
Cheers,
Corey

I do not own a Pyxis, so I just consulted the user manual.
Your procedure seems to be correct.

When you tested this - you did use the built-in LCD, right?

Because if you were using the external LCD you would have to set it the parameter to be displayed on to the EVF.

Just a wild guess by me:
As far as I remember the Focus Assist toggle per default is mapped to the F1 button.
Can you check this and if yes, un-map that? Maybe there is a bug preventing double-mapping.

Also try to map any other function to the One Shot AF button to see if any other is working. Maybe the whole remapping for that button got borked.

I have the same problem on the Blackmagic Pocket Cinema Camera 6K G1. You simply can not use that button and assign a different function. I think it's a firmware bug.

How do we open a "bug/defect" for this?

I have the same problem with the BMCC 6K FF. I use manual lenses, and I have tried to remap that button to no effect.
