Hi @Angel_OLG
There is an on-board debugger on the board. It supports J-Link and CMSIS-DAP probes.
Please refer to the steps below to update the debugger firmware to J-Link (FRDM-MCXN947).
To update the firmware using the firmware update utility (which is included in the LinkServer installation package), the MCU-Link must be powered up in ISP mode. Follow these steps to configure MCU-Link in ISP mode and update the MCU-Link firmware.
- Disconnect the board from the host computer, short jumper J21, and reconnect the board. The D11 (Red) MCU-Link status LED lights up and stays on. For the D11 LED details, see MCU-Link status LEDs.
- Download the LinkServer utility from https://nxp.com/linkserver and install the LinkServer installer. For example download and install ‘Linkserver 1.4.85 installer for Windows’.
- Navigate to the
MCU-LINK_installer_Vx_xxx directory, where Vx_xxx indicates the version number. For example, MCU-LINK_installer_3.119.
- Follow the instructions in the
readme.txt to find and run the firmware update utilities for CMSIS-DAP or J-Link versions.
- Disconnect the board from the host computer, open jumper J21, and reconnect the board. The board enumerates on the host computer as a WinUSB or HID device (depending on the firmware version).
