Updating debugger firmware

The MCX-W72-EVK board comes with a CMSIS-DAP-compatible debug interface (known as MCU-Link). This firmware in this debug interface may be updated using the host computer scripts. This firmware is typically used when switching between the default debugger protocol (CMSIS-DAP) to SEGGER J-Link, or for updating this firmware with new releases of these. This section contains the steps to re-program the debug probe firmware.

NXP provides the MCU-Link utility, which is the recommended tool for programming the latest versions of CMSIS-DAP and J-Link firmware onto MCU-Link. The utility can be downloaded from MCU-Link Debug Probe.

These steps show how to update the debugger firmware on your board for Windows operating system. For Linux OS, follow the instructions described in MCU-Link user guide, MCU-Link Debug Probe.

1. Install the MCU-Link utility.

2. Unplug the USB cable of the board.

3. Install the jumper on JP20.

4. Connect the probe to the host via USB (use Link USB connector).

5. Open a command shell and call the appropriate script located in the MCU-Link installation directory, <MCU-Link install dir>.

   1. To program CMSIS-DAP debug firmware: <MCU-Link install dir>/scripts/program_CMSIS.

   2. To program J-Link debug firmware: <MCU-Link install dir>/scripts/program_JLINK.

6. Remove the jumper on JP20.

7. Re-power the board by removing the USB cable and plugging it in again.
