Updating debugger firmware
The KW45B41Z-LOC 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 https://www.nxp.com/design/microcontrollers-developer-resources/mcu-link-debug-probe:MCU-LINK.
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, https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-/mcu-link-debug-probe:MCU-LINK.
Install the MCU-Link utility.
Unplug the board’s USB cable.
Install the jumper on JP12.
Connect the probe to the host via USB (use Link USB connector).
Open a command shell and call the appropriate script located in the MCU-Link installation directory, <MCU-Link install dir>.
To program CMSIS-DAP debug firmware: <MCU-Link install dir>/scripts/program_CMSIS.
To program J-Link debug firmware: <MCU-Link install dir>/scripts/program_JLINK.
Remove the jumper on JP12.
Re-power the board by removing the USB cable and plugging it in again.
