Tool/software: Code Composer Studio

Hello, TI Engineers

When I use HALCoGen to gennerate some driver codes, I found a sys_selftest.c file. I don't know what the file is used for? I tried to delete it. After it deleted, the project can not be built. when I check map file, it take account of more than 5000B memory. Could anybody help me to delete it?

Thanks!

Regards!

    Hello Xinyu,

    This file contains the diagnostic features for functional safety. The functions in sys_selftest.c are called in sys_startup.c, for example, checkRAMECC(), can1ParityCheck(), memoryInit(), cpuSelfTest(), etc. It's better to keep sys_selftest.c in your project.

    If you really want to remove this file:

    1. disable all the features listed in SAFETY INIT in HALCoGen

    2. comment out the function call of memoryInit() in sys_startup.c

    3. sys_selftest.c contains data abort handler, and it was called by dabort.asm. So copy this function to somewhere else

    /** @fn void custom_dabort(void)

    *   @brief Custom Data abort routine for the application.

    *

    *   Custom Data abort routine for the application.

    */

    void custom_dabort(void)

    {

       /* Need custom data abort handler here.

        * This data abort is not caused due to diagnostic checks of flash and TCRAM ECC logic.

        */

    /* USER CODE BEGIN (42) */

    /* USER CODE END */

    }

    4. exclude sys_selftest.c from project built

    Hello, Wang

    In addition, I want to know more about selftest of TMS570. If I use HALCoGen to configure drivers of TMS570. Selftest would run periodically on the TMS570 chip. Or I should call the function when I need to do selftest for TMS570.

    Thanks!

    Regards!
