TDA4VM: FUSA Mechanism about illegal operation and instruction trapping && stack overflow detection

Part Number: TDA4VM
Other Parts Discussed in Thread: SYSBIOS

Hi:

    We are doubt about the FUSA Mechanism :

  1.    "Illegal operation and instruction trapping" for C66X/C7X/R5F;
  2.    "Stack Overflow detection " AND " Stack Underflow detection" for  C66X/C7X;

   Do these mechanisms need to be implemented by our own code ? Or is this a feature of IP that has been enabled by default ?

    Thanks a lot !

    Hi Ivan,

    These mechanisms are referring to the OS handling and follow-up when illegal operations, and stack overflow/underflow are encountered.

    The TI SDK does not explicitly implement these mechanisms, in that the default behavior from the TI SDK implementation of whichever OS is in use Sysbios / FreeRTOS / SafeRTOS / Autosar / other,  may not meet your safety needs.  As such, implementation / understanding is responsibility of safety integrator.

    Regards,
