How to enable GPIOs which are DISABLED after reset

Hi,

I'm creating a project with the MKE04Z64VLD4 microcontroller with MCEXpresso (v10.3.1 [Build 2233]) and its built-in Pins and Clocks tools. I've downloaded the MCUXpresso SDK (2.5.0) from nxp using MCUXpresso SDK Builder.

Problem is I try to use pins 36, 37 (PTC7,PTC6) as GPIO outputs but writing to them has no effect on the pin.

The BOARD_InitPins() function created by the Pins tool includes calls to GPIO_PinInit() for each pin, but calls to GPIO_PinWrite() seem not having effects on the output.

Is there any other step required for using those pins?

Victor
