I want to create a multi-core project in MCUXpresso, for the RT1170-EVK.
I want to use the M7 as the master and the M4 as the slave.
However, with this setup, I cannot use ConfigTools to generate the pinmux.c code.
I can use ConfigTools as per usual, until I click on 'Update Code'.
At this point, I get a warning:

When I press 'OK', the code in pinmux.c is not changed (as one would guess from the fact that it is greyed out). I cannot tick the box next to 'Pins'.
I assume it is related to the warning that I get in the ConfigTools view:

I can do the Pinmux as per usual in the M7 Master project, but I need to configure some pins in the M4 Slave project.
Does anyone know how I can resolve this?
