# Forum: ARM programming with GCC/GNU tools LPC1768 + FreeRTOS not working

Hey,

since weeks I am trying to get freeRTOS to work on a NXP LPC1768 Cortex
M3 with CodeSourcery G++ Lite Compiler (using Eclipse IDE).

I have tried an altered CMSIS startupfile (with interrupt vector table
adapted to freeRTOS handlers) and the included startup-file of the
codeRed demo-project. Neither of them is working.
The university I am attending gave me the evaluation board where the
cortex m3 is placed onto, so it is not a commercial version. However
nobody at university can tell me what the problem is, or why it is not
working.

Within the main() function I just create one simple Task which is
supposed to toggle a LED, but already the creation of the task fails and
the programm does not even come to start the scheduler.

I have added the eclipse project in the hope that somebody can help me.
Maybe somebody has a working hardware of the lpc1768 and can test the
project, or somebody can tell me just by looking at the code where the
problem is.
Would really appreciate any kind of help.

Best regards,
peter

Try instead of

 xTaskCreate(vTask1, (const signed char * const)("Task 1"),configMINIMAL_STACK_SIZE,NULL,tskIDLE_PRIORITY,NULL );
  int main( void ) { init_System(); /* Create one task. */ xTaskCreate(vTask1, "Task1",configMINIMAL_STACK_SIZE*10,NULL,tskIDLE_PRIORITY+1,NULL ); GPIO_SetValue(1, 0x02); /* Turn on P1.1 */ /* Start the scheduler so our tasks start executing. */ vTaskStartScheduler(); /* If all is well we will never reach here as the scheduler will now be running. If we do reach here then it is likely that there was insufficient heap available for the idle task to be created. */ for( ;; ); return 0; } /*-----------------------------------------------------------*/ void vTask1( void *pvParameters ) { //for( ;; ) //{ GPIO_SetValue(1, 0x02); /* Turn on P1.1 */ vTaskDelay(2000/portTICK_RATE_MS); /* Insert delay */ GPIO_ClearValue(1, 0x03); /* Turn off P1.1 */ vTaskDelay(2000/portTICK_RATE_MS); /*Insert delay */ GPIO_SetValue(1, 0x02); /* Turn on P1.1 */ vTaskDelay(2000/portTICK_RATE_MS); /* Insert delay */ //} } 


Does it turn on? -> Init OK Port OK

Does it turn on, off, on, off -> Task has been executed
