Hi,

I am a beginner in freertos. Please Help me

When I compile this small below program it has compiled but it is not make.i am getting Link Error.

Link Error: Undefined: “vApplicationStackOverflowHook” Referenced from “vTaskSwitchContext” in.

(and i am using Coldfire MCF52259 Microcontroller)

#include “FreeRTOS.h”
#include “task.h”
#include “queue.h”
#include “timers.h”
void mytask(void *pvParameters)
{
while(1)
{
MCF_GPIO_DDRTC=0x0F;
MCF_GPIO_SETTC=0x0F;
vTaskDelay( 500 / portTICK_RATE_MS);
MCF_GPIO_CLRTC=0x0F;
}
}
int main(void)
{

xTaskCreate(mytask,(signed char*) "mytask", configMINIMAL_STACK_SIZE, NULL, 1, NULL);
return 0;

}


This is FreeRTOSConfig.h file which i have used for this above program

#ifndef FREERTOS_CONFIG_H
#define FREERTOS_CONFIG_H

/* Library includes. */
#include “common.h”

Hello,
it is because you have asked to check for stack overflow in your FreeRTOSConfig.h:
configCHECK_FOR_STACK_OVERFLOW
Set it to 0 if you want Stack overflow disabled.
Altough I recommend to have it enabled. Simply add something like this to your application:

void FRTOS1_vApplicationStackOverflowHook(xTaskHandle pxTask, signed portCHAR pcTaskName)
{
/
This will get called if a stack overflow is detected during the context
switch. Set configCHECK_FOR_STACK_OVERFLOWS to 2 to also check for stack
problems within nested interrupts, but only do this for debug purposes as
it will increase the context switch time. /
(void)pxTask;
(void)pcTaskName;
taskDISABLE_INTERRUPTS();
/
Write your code here … */
for(;:wink: {}
}

If you are using ColdFire V2 (MCF52259) with CodeWarrior, then you might have a look at my Processor Expert component for FreeRTOS: it supports many cores, including ColdFire:


I hope this helps.
