How to install Segger Firmware in MCX A and MCX N

[Angel_OLG]

One of us customer is being trained on the MCX A/N families. The customer has the following boards: FRDM-MCXA153, FRDM-MCXA46, and FRDM-MCXN947.

They have issues to program the boards using the default P&E Firmware, and we can fix the issue by installing the SEGGER Firmware. Is there any guideline to install the firmware on this  MCX Families?

Regards!

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.

1. 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.
2. 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’.
3. Navigate to the MCU-LINK_installer_Vx_xxx directory, where Vx_xxx indicates the version number. For example, MCU-LINK_installer_3.119.
4. Follow the instructions in the readme.txt to find and run the firmware update utilities for CMSIS-DAP or J-Link versions.
5. 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).

Hello @Alice_Yang , good day!

Thanks for your quick answer. I'm assuming the same process apply to the MCX A153, jumper JP8 and then follow the steps. Am I correct?
