FreeRTOS with SD Card Lib

Official Hardware Mega Due

Hey,

I've a Question about the combination of the

#include <FreeRTOS_ARM.h>

and

#include <SD.h>

Libraries. My problem is that I can't read or write to the SD Card after
I startet my tasks with

  vTaskStartScheduler();

Maybe somebody know this problem or some solution for that?
Before I start my tasks the SD Card read/write works fine.

Thanks for your Support:-)

Yeah I've solved my problem!:slight_smile:

You have to disable the interrupts before you read or write from/to an SD card :slight_smile:

noInterrupts(); 
writeToSD();     
interrupts();

An other problem can be the task Stack_Size.

xTaskCreate(Thread_1, NULL, Stack_Size , pvParameter, 3, NULL);
