MCU Link Firmware update.

We will need the firmware to update the LPC55s69 on the board, the MCU Link firmware version 2.263 is compatible with the MCX.

You may need the EVK connected to the computer under DFU mode, in the schematic of the EVK does not mention the DFU but has the named jumper of ISP [JP21] MCX - N or [JP8] MCX - A, sure you put the LPC55s69 in ISP, not the MCX, review the schematic below.

MCX - N

MCX - A

When you have installed this version on your computer, go to the locations.

ROOT: C:\nxp\MCU-LINK_installer_2.263\scripts

Then open the CMD prompt console and run the script for CMSIS.

The console asks if you have the appropriate jumper, if yes click enter again.

If everything is right the message successfully will appear.

Then in the MCUXpresso, you can see the debugger probe.

Happy Debugging.
