    Description

      Got a simple simple GUI running on MIMXRT1064-EVK: i.MX RT1064.

      3-4 screens. Navigate to next / previous screen using Prev/Next buttons.

      The last screen has a Qt Chart (Bar graph).

      Works fine using the Bare Metal and Desktop kits.

      But when using the FreeRTOS kit, the GUI locks up every single time I try to navigate to that last screen with the Qt Chart.

       

      I click the Next button, which essentially hides the current screen, and shows the next screen. Everything hangs. The Next button doesn't get repainted, the last screen never gets displayed.
