  • sprintf crashing

    Unfortunately sprintf is crashed. Any idea ?
    Our target is:
    1. embOS for TI MSP430 (build Debug (D)) with IAR workbench ver. 5.10.4 (5.10.4.50168)
    2. MSP430F5437 CPU with internal developed board

    3. start project which we use is Start_F5438
    Thx

  • Hello,

    we are not aware of any problems with sprintf() and embOS.

    I tried to reproduce the problem with IAR simulator and our embOS start project but I cannot see any problem here.
    My task looks like this:

    C Source Code

    1. char s[20];
    2. static void HPTask(void) {
    3. sprintf(s, "Test = %d", 123);
    4. while (1) {
    5. LED_ToggleLED0();
    6. OS_Delay (50);
    7. }
    8. }


    What exactly happens when you talk about a crash?
    Did you try to call sprintf() without embOS?
    Is the character array as first paramter for sprintf() bigh enough?

    Regards,
    TIl

  • Yes, depending on the string functions like printf() and sprintf() uses a lot of stack.
    Please ensure that your task stack size is big enough.
