Hello, @Sam_ECU
Sorry for the late answer. I have investigated your files and I think you do not export the Simulink project properly. Even after you press the Deploy button and the model is building, it is not enough to just import the folder evkmimxrt1010_gpio_pollingConfig into the MCUXpresso IDE. You also have to press the Export button from the Hardware Settings -> Hardware Implementation -> Target Hardware Resources-> Tools Paths. This Export button will add some files in the evkmimxrt1010_gpio_pollingConfig folder to make it compatible with the MCUXpresso IDE.
So, for a short recap, you have to:
1. Build the model from Simulink which will result the folder evkmimxrt1010_gpio_pollingConfig and other files.
2. Export the generated project from the model, pressing the Export button as I described above.

3. Follow the steps from https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/iMXRT-Model-won-t-solve-when-activating... for getting the generated project into the MCUXpresso IDE.
I will also attached, my generated project to try it and tell me if it works.
Hope this is helpful.
Regards,
Stefan
