  • [SOLVED] JTRST or NRST ?

    I am debugging a custom board with a STM32G431C8 MCU and have the JLink connected with the 5-wire JTAG connection. My "reset" is the MCU JTRST pin not the NRST pin. Is this correct for debugging with the 5-wire Jtag?
  • TRST: Test reset signal to reset the TAP controller and/or debug logic.
    J-Link does not really use this signal.

    nRESET / NRST: Reset pin of MCU. May be used on STM32 MCUs to do a connect under reset.

    TRST is not a replacement for NRST.
