    Lyoo,

    The problem you are facing has an issue fix.

    Open your linker command file (sys_link.cmd) and add red ligne as showed in the following example.

    /*----------------------------------------------------------------------------*/
    /* Section Configuration                                                      */

    SECTIONS
    {
        .intvecs : run = VECTORS , load = VECTORS_
        .text    : run = FLASH   , load = FLASH_
        .const   : run = FLASH   , load = FLASH_
        .cinit   : run = FLASH   , load = FLASH_
        .pinit   : run = FLASH   , load = FLASH_
        .bss     : {} > RAM
        .data    : {} > RAM

    /* USER CODE BEGIN (4) */
        .sysmem  : {} > RAM
    /* USER CODE END */
    }

    /* USER CODE BEGIN (5) */
    /* USER CODE END */

    Some of the code in the Real Time Library are using a section named .sysmem.
    This section has to be mapped in RAM.

    In this example, the sys_link.cmd was generated by Halcogen,
    In order to be sure Halcogen will not remove this new statement, it as to be placed in between a pair of
    /* USER CODE BEGIN (x) */     and /* USER CODE END(x) */

    Best Regards,

    Jean-Marc
