Опубликовано 20 июня, 2011 · Жалоба

Добрый день. Помогите побороть FreeRTOS, на данный момент все собирается, запускаю в Debug и в Debug Log вижу:

Mon Jun 20 12:45:17 2011: Interface dll version 2.3.5.0
Mon Jun 20 12:45:18 2011: Device : MSP430F5438

Mon Jun 20 12:45:18 2011: External voltage : 0.0 V

Mon Jun 20 12:45:18 2011: VCC voltage : 3.0 V

Mon Jun 20 12:45:21 2011: Download complete.

Mon Jun 20 12:45:21 2011: Loaded debugee: U:\IAR Projects\FreeRTOS_7.0.1\Debug\Exe\freertos7.d43

Mon Jun 20 12:45:21 2011: Target reset

Порядок действий такой:

1. Скачал FreeRTOS 7.0.1 c www.freertos.org.

2. Создал в IAR Embedded Workbench for MSP430 4.20 пустой проект.

3. Добавил к проекту файлы из папки Source(tasks.c, list.c, queu.c), папку Include, все содержимое папки FreeRTOS\Source\portable\IAR\MSP430X.

4. Из папки FreeRTOS\Demo\MSP430X_MSP430F5438_IAR добавляю FreeRTOSConfig.h его немного правлю и в результате получаю:

5. Пробую собрать, получаю следующие ошибки:

Error[e46]: Undefined external "vApplicationSetupTimerInterrupt" referred in port ( U:\IAR Projects\FreeRTOS_7.0.1\Debug\Obj\port.r43 )
Error[e46]: Undefined external "vConfigureTimerForRunTimeStats" referred in tasks ( U:\IAR Projects\FreeRTOS_7.0.1\Debug\Obj\tasks.r43 )

6. Добавляю в port.c реализацию данных функций:

/* The MSP430X port uses this callback function to configure its tick interrupt.

configTICK_VECTOR must also be set in FreeRTOSConfig.h to the correct
interrupt vector for the chosen tick interrupt source.  This implementation of
vApplicationSetupTimerInterrupt() generates the tick from timer A0, so in this
case configTICK_VECTOR is set to TIMER0_A0_VECTOR. */
void vApplicationSetupTimerInterrupt( void )
{
const unsigned short usACLK_Frequency_Hz = 32768;

    /* Ensure the timer is stopped. */
    TA0CTL = 0;

    /* Run the timer from the ACLK. */
    TA0CTL = TASSEL_1;

    /* Clear everything to start with. */
    TA0CTL |= TACLR;

    /* Set the compare match value according to the tick rate we want. */
    TA0CCR0 = usACLK_Frequency_Hz / configTICK_RATE_HZ;

    /* Enable the interrupts. */
    TA0CCTL0 = CCIE;

    /* Start up clean. */
    TA0CTL |= TACLR;

    /* Up mode. */
    TA0CTL |= MC_1;
}

    TA1CTL = 0;

    /* Run the timer from the ACLK/2. */

    /* Start up clean. */
    TA1CTL |= TACLR;

    /* Continuous mode. */
    TA1CTL |= MC__CONTINOUS;
}
/*-----------------------------------------------------------*/

7. Все собирается, делаю демо проект, следующего содержания:

#include <stdio.h>
#include <msp430x54x.h>

#include "../include/FreeRTOS.h"
#include "../include/task.h"
#include "../include/queue.h"

void vHelloWorldTask( void *pvParameters ) {
    for(;; ) {
        printf( "Hello, world\n" );          
        vTaskDelay( 100 );
    }
    vTaskDelete( NULL );
}

void main( void ) 
{ 
    //Stop watchdog timer to prevent time out reset
    WDTCTL = WDTPW + WDTHOLD;   
    
    if( xTaskCreate( vHelloWorldTask, "HelloWorld", 100, NULL, 1, NULL) != pdTRUE ) {
        printf( "Can't create task.");
    }
    
    vTaskStartScheduler();
    for(;; ) {}    
}

8. Получаю Target Reset и все.
