RL-RTX can not work with RL-FlashFs

I don't know much about this. But maybe:

1. In RTX_Conf_LPCxxxx.c, please enable the "Check for the stack overflow". Make sure you provide enough space for all the stacks.

2. os_sys_init() ->

http://www.keil.com/support/man/docs/rlarm/rlarm_os_sys_init.htm

[start]
The os_sys_init function initializes and starts the Real-Time eXecutive (RTX) kernel.

The os_sys_init function does not return. Program execution continues with the task identified by the task argument.
[end]

Since you choose to use an OS on your platform, it is better to initialize and start the (RTX) kernel first, before you do anything else.

First thanks to try to answer to my question
To Per Westermark : I'am not sure to understand what do you really mean. That's not I never get out of the main function, it's I never go in the main function. So I never go to the rest of my program which for the moment is very "light" because I have just an init task which launch a task that switch the led of my demo board.

__task void led (void) {

  LED_Init (); /* Initialize LED display module    */
  for (;;) {
    LED_Out (leds);/* Update LED Driver  */
        leds=leds<<1;
        if(leds==0x10)
                leds=0x01;
    os_dly_wait (20);
  }
}

__task void init (void) {

        static FILE *f = NULL;

        if (finit() == 0) {
        f = fopen ("M:\\toto.txt","w");

        if(f!=NULL)
                fclose(f);
        }
  /* start task led */
  t_led    = os_tsk_create (led, 1);
  os_tsk_delete_self ();
}


int main (void) {

os_sys_init (init);
/* Initialize RTX and start init    */
}

To John Linq :
I have

#ifndef OS_STKCHECK
 #define OS_STKCHECK    1
#endif

but I check I never get into

os_stk_overflow (OS_TID task_id)

So I think there is no stack overflow (and moreover it is a really small program).

next you are right I should do

os_sys_init (init);

before doing everything else so I put the "FlashFS" call in the init task (like I post). but that don't change anything.

When I launch the program in debug mode I found that I go to

void _sys_exit (int return_code) {
   /* Endless loop. */
   while (1);
}

and of course I stay in it because it's a "while(1)" that why I never go to main, I go to _sys_exit before the main function is call

Does the flash file system requires dynamic memory? In that case - have you supplied a large-enough heap?

yes it does. Keil report that you must define at least 0x400 bytes of heap.

Thanks a lot!!
I forgot to set the heap size (it was 0x00) and now it seams to work well!!

Thank you all.
