FreeRTOS SYSTickTimer frequency

Hi

I am trying to run freeRTOS on STM32f407 so I want to know at what frequency my clock will run let me share you my clocking diagram too.

another doubt how to enable SysTick_Handler.

other external interrupt I have enabled like this

NVIC_SetPriority(TIM2_IRQn, 0x00);

NVIC_EnableIRQ(TIM2_IRQn);

NVIC_SetVector(TIM2_IRQn, (uint32_t)&TIM2_IRQ_Handler);

Note :

#define configSYSTICK_CLOCK_HZ ( configCPU_CLOCK_HZ )
#define configCPU_CLOCK_HZ ( ( unsigned long ) 16000000 )

is it correct

Hello,

First , please use CubeMX to generate a FreeRTOS project.

Second, in CubeMx, FreeRTOS needs system tick not a timer for its kernel tick. Need to select another timer for HAL:

Example TIM6:

Third, the system tick FreeRTOS kernel is running at 1ms rate:

From FreeRTOSConfig.h:

#define configTICK_RATE_HZ ( ( TickType_t ) 1000 )

Attached an ioc file.

Hope that helps.

What @mƎALLEm means is that you need to use the proper formatting for the code that you did include in your post.
