Error Log messages: Target Status: IP_TAP_CNTL_-16 is null

Other Parts Discussed in Thread: HALCOGEN

Hello, 

I built my project to generate the .elf file with Arctic Studio. But when I loaded image to the TMS570 board and debugged with Code Composer Studio, it couldn't use printf to print out the message on the console. What do I want to ask is there are some Error Log messages: Target Status: IP_TAP_CNTL_-16 is null. What did this mean?

Besides, I download the TMS Safety MCU Demos, but I don't know how to send commands from PC through SCI. Should I push any buttons in the keyboard or on the TMS570 board? 

I hope anybody can help me to solve my problem! 

Thank you in advance.

    Vanessa,

    I see the same error message from time to time. But I see the printf output to the console independent of the error message.

    There is one addition required to the linker command file from what HALCoGen generates to get printf to work. See highlighted line below:

    SECTIONS
    {
        .intvecs : {} > VECTORS
        .text    : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .const   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .cinit   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .pinit   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .bss     : {} > RAM
        .data    : {} > RAM

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

    Let me know if this works for you.

    What commands do you want to send via SCI?

     

    Regards,
