Simple testing code for teensy 3.2 doesn't work

[23ars]

Hi guys,

I have a question related to teensy 3.2. I wrote a simple C code

#include "MK20D7.h"



int main(void)
{

	PTC->PDDR=1<<5;//set direction

	PTC->PSOR=1<<5;
	int i;
	while(1){


	}
    return 0;
}

for setting high the pin 13 on Teensy. After I uploaded the hex with Teensy Loader, nothing happened. I verified the controller's datasheet, I verified the memory map, everything seems OK, but the led is not lighting.

To be sure that my Teensy board is working, I wrote the next code in Arduino IDE and uploaded and the led was blinking.

int led = 13;


void setup() {                

  pinMode(led, OUTPUT);     
}


void loop() {
  digitalWrite(led, HIGH);   
  delay(1000);               
  digitalWrite(led, LOW);    
  delay(1000);               
}

Maybe I'm missing something. I would appreciate every answer!

PS: I used Kinetis Design Studio and code is compiled with arm-none-eabi-gcc.

as the problem is with KDS maybe the overall initialization is not the same (enabling the ports etc). Did you check with the KDS community if this program is complete? the KDS example I have looks somewhat different. did you try the PE?

Maybe I'm missing something.

Perhaps enabling the clock to PORTC in the SIM clock gate registers?

I would appreciate every answer!

Even the "answer" to just use Arduino instead of KDS?

And perhaps also the mux setting in the port config register for that pin?

Thanks a lot! I didn't try the PE...
