How to use MCAL with project configured for FreeRTOS MPU for S32K344

HemantK — Wed, 14 Dec 2022 20:01:20 GMT

Hello All,

I have created a simple FreeRTOS MPU project by modifying "FreeRTOS_Toggle_Led_Example_S32K344" and added DIO MCAL to toggle on board LED.

My modified ReceiveTask task looks like this now:

void ReceiveTask( void *pvParameters ) { (void)pvParameters; BaseType_t operation_status; BaseType_t count = 0; uint8_t currentLevel = STD_HIGH; for( ;; ) { operation_status = xSemaphoreTake(sem_handle, portMAX_DELAY); configASSERT(operation_status == pdPASS); Dio_WriteChannel(DioConf_DioChannel_RED_LED, currentLevel); currentLevel =~currentLevel & 0x1; if(count++ > 10) { //testResult = 0x5AU; } } }

But as soon as it try to execute "Dio_WriteChannel(DioConf_DioChannel_RED_LED, currentLevel);", I get memory exception

But no issue is seen if I comment above line of code.

In short can you please guide me as how I can use MCAL with FreeRTOS using MPU.

Regards,

Hemant Kapoor

Hi HemantK,

what is the FreeRTOS package's name you are using?

Best regards,

Dan
