I think I have found the issue.
As on i.MX RT1050 Processor Reference Manual, page 998-999, here below the GPIO registers allowed on RT1050 family

but on evkbimxrt1050_ew_gui_smart_thermostat from SDK_2_10_0_EVKB-IMXRT1050, the IGPIO module is configured to use CLR, SET and TOGGLE register (instead of directly DR register)

I see that GPIO library is provided for both method

I tried to modify the IGPIO module configuration

and now Termo and all Display examples are working
