STM32L452CE, programming failure

Staff: Steve M.

  • Hello I'm using Cyclone FX programmer to program my STM32L452CE. 

    1. I am using PORT H debug pins to program it with SWD configuration.

    2. As I am giving power externally to the controller I have not connected any power jumpers and deselected the Provide Target Power setting in Image creation application.

    3. I have connected SWDIO(PIN7), SWCLK(PIN9), GND(PIN4) and RESET(PIN15) pins from PORT H to my controller.

    3. After pressing start button to program, I observed $0007: An error occurred while entering debug mode.

    Can I get a solution to this problem asap.


    Thanks,
    Anirudh

    • Hi Andirudh,

      Thank you for reaching out to us on this issue. Even though you are powering your target device externally, you still need a VCC connection to our Cyclone to recognize target power from the device. Make this connection at Pin 1 of Port H and let us know if this solves the issue.

      Steve
