Delay functions (HAL_Delay,DWT_Delay,for loop.... ) doesn't work on my STM32f429 board, is this caused by hardware ?

There are some posts about generated code about HAL_Delay being different from CubeMX 5+. Similar issue here?

some projects you have to enable systick, is it running ?

void initSysTick() {
 int ticks = 0x6000; // 32MHz 1mS count
 SysTick->LOAD = (uint32_t)(ticks - 1UL); /* set reload register */
 NVIC_SetPriority(SysTick_IRQn, (1UL << __NVIC_PRIO_BITS) - 1UL); /* set Priority for Systick Interrupt */
 
 SysTick->VAL = 0UL; /* Load the SysTick Counter Value */
 SysTick->CTRL = SysTick_CTRL_CLKSOURCE_Msk |
 SysTick_CTRL_TICKINT_Msk |
 SysTick_CTRL_ENABLE_Msk; /* Enable SysTick IRQ and SysTick Timer */
}

If you are in debug mode, open the HW peripheral window and manually look at your GPIO and try to change off/on state. Just to make sure the HW and the GPIO registers are ok.
