Why does the Nios® V Micrium MicroC/OS-II(uC/OS-II) program halted during program execution?

Environment

  • Intel® Quartus® Prime Pro Edition
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.4 and earlier, you may experience Nios® V uC/OS-II program halted during program execution. The event may occur when the following conditions are met:

    1.  You are using the Nios V uC/OS-II BSP package.

    2.   You enabled hal.enable_runtime_stack_checking

    This is due to the expected behavior of the Nios V program. If alt_sbrk() is called from within a uC/OS-II task, it will trigger an ebreak exception notifying the user of a stack overflow condition and halt the program.

    Resolution

    Users may disable the 'hal.enable_runtime_stack_checking' setting in the Nios V uC/OS-II program.

    This is scheduled to be fixed in a future release of Intel® Quartus® Prime Edition Software.
