STM32F4 with ECC2 kernel problem

[kamejoko80]

Hello everyone,

I've encountered a problem regarding to ECC2 kernel type.

When build the source I got the following error message :

Code: Select all

C:\gnu\ARM\bin\arm-none-eabi-ar.exe: creating libee.a
LD
libee.a(ee_altick.o): In function EE_oo_run_next_task':

collect2.exe: error: ld returned 1 exit status

Check out the source and it seems doesn't support multi task for ARM cortex-M4 (just only __MONO__ BCC1 and BCC2) , is it right ?
I’m using “EE_RT-Druid-2.4.0-juno-win32-x86_64″, and here is my OIL file :

    TASK Task2 {

    };

    EVENT TimerEvent  { MASK = AUTO; };

    COUNTER Counter1 {

        MAXALLOWEDVALUE = 0xFFFF ;
        TICKSPERBASE = 1;
    };

    ALARM AlarmTask1 {
                COUNTER = Counter1;
                ACTION = SETEVENT { TASK = Task1; EVENT = TimerEvent; };
                AUTOSTART = TRUE { ALARMTIME = 250; CYCLETIME = 500; };
    };

    ALARM AlarmTask2 {
                COUNTER = Counter1;
                ACTION = ACTIVATETASK { TASK = Task2; };
                AUTOSTART = FALSE;
    };

};

Thanks and Best Regards

Hi,

yours is a classic First-Time-I-Touch-OIL error :) (To be honest we should add a check for this kind of inconsistence in RT-Druid, but we have no time...).

In your configuration you are using multiple stacks without turning on the multistack switch in CPU_DATA OIL field. Try the following:

Code: Select all

     CPU_DATA = CORTEX_MX {
         MODEL = M4;
         APP_SRC = "code.c";
         //COMPILER_TYPE = KEIL; 
         COMPILER_TYPE = GNU;
         MULTI_STACK = TRUE; /* <-- Toogle this */
      };

Errico
