  • STM32L4xx NJTRST needed?

    Hi,

    when dugging the mentioned MCU (KEIL IDE) i am not able to stop the debugger once the program is started. Do i need the NJTRST pin for this purposed (it is not connected). Is there a way to use JTAG without having NJTRST connected at all?

    Regards
  • Hi,


    NJTRST is not necessary to halt the device.
    Please refer to the interface description for further information.

    Does it work in J-Link Commander (jlink.exe)?


    Best regards,
    Niklas
