Toggle Port C Pin

Shubhang S

Hello,

I am trying to toggle the Port C Pin 0 using the debugger (No eval board attached) for the device STM32F407 with the following code:

        #include        "stm32f4xx_hal.h"

        void delay()
        {
                for(int i = 0; i < 100000; i++);
        }

        int     main    (void)  {
                while(1)
                {

                        GPIOC->MODER = 0x01;
                        GPIOC->BSRR ^= 1;
                        delay();

                }
        }

When stepping thorough the code, the GPIO in peripherals Window does not show any change to the values of MODER and BSSR. Its always 0 and does not work for other ports also. What is wrong?
