  • OS_ERR_ILLEGAL_IN_TIMER (161) without Software Timers

    i get a error 161, but i don't use any software Timers.
    and the only OS-functions which i call in the ISRs are "OS_SignalEvent() ; OS_EnterInterrupt() and OS_LeaveInterrupt().
    i use a MSP430F2618 and the 3 tasks are for communicating with another uC over spi.

    the Error occurs while calling OS_free after a few times (not in the ISR)
    i always use OS_malloc before OS_free.

    The Error is: OS_ERR_ILLEGAL_IN_TIMER -> " Illegal function call in an interrupt service routine:A routine that may not be called from within a software timer has been called from within a timer."

    what could be the Problem?
    Thank you for any help.

  • Gringo, could you please give some more basic information?

    How to report embOS related issues:

    1. Which embOS do you use?
    This should include CPU, compiler and version.
    For example: embOS for ARM version 3.60d with IAR workbench 5.11 (embOS_ARM_IARV5 V360d).
    2. Which CPU and eval board do you use?
    For example: AVR32AP (AP7000) CPU with Atmel NGW100 eval board.
    3. Which start project do you use?
    Did you download e.g. a trial package from the Segger website?

    Thanks.

    Could you please also check which function calls OS_Error()? You can get this information from your call stack window or
    you can set OS_Status again to 0 and leave the while() loop and OS_Error() function. You will return to that function which calls OS_Error() before.
    Please read the forum rules before posting.

  • all right

    Hello,
    i found the Error now, it was a wrong definition of my used Mailbox Size.
    My code was:

    C Source Code

    1. void main( void )
    2. {
    3. OS_IncDI();
    4. OS_InitKern();
    5. OS_InitHW();
    7. HAL_BOARD_INIT();
    8. HalDriverInit ();
    10. // Init functions for Tasks
    11. OS_CREATETASK(&TCB_LABELING, "Labeling Task", Labeling_Task, 70, StackLabeling);
    12. OS_CREATETASK(&TCB_SPI, "SPIProcess Task", SPIProcess_Task, 30, StackSPI);
    13. OS_CREATETASK(&TCB_POLLRXBUFF, "PollRXBuff Task", PollRXBuff_Task, 80, StackPollRXBuff);
    15. //Init function for MailBoxes
    16. OS_CREATEMB(&MBSlaveSend, sizeof(_os_messageEvent) , sizeof(MBSlaveSendBuffer), &MBSlaveSendBuffer);
    18. // create Semaphores
    19. OS_CreateRSema(&SemaStatusLED);
    21. OS_DecRI();
    22. OS_Start();
    23. }
    Display All


    The Error was that my message has 3 Bytes(_os_messageEvent) -> ( 1Byte datalength and one Pointer(2byte) to the data)

    the correct Mailbox definition is:

    C Source Code

    1. OS_CREATEMB(&MBSlaveSend, sizeof(_os_messageEvent) , sizeof(MBSlaveSendBuffer)/sizeof(_os_messageEvent), &MBSlaveSendBuffer);


    i think the memory was overwritten by the Mailbox, or in the other direction the code has corrupted the mailbox.
    The Error: OS_ERR_ILLEGAL_IN_TIMER has nothing to do with Timer or ISR in my case. (maybe internal Timer or ISR of the Mailbox or Some semaphore)

    But thank you anyway...

    - i use the version 3.62c at the moment as a trial ( licence is in progress in the company)
    - with IAR for MSP430 v 4.21 on a MSP430F2618
    - i made my own hardware Board with the MSP430 (and a CC2430, connected to the MSP over SPI nothing else)

    cheers from Switzerland
