How to restore MCU-Link firmware

[Maccha_Neko]

I obtained an FRDM board and installed MCUXpresso on a Linux (under VMware....Host OS is Windows11).

When I launched the debugger, there was a firmware update available, so I proceeded with it.

 However, during the USB reconnection, it took a long time, and I encountered an error.

Since then, the FRDM board is recognized as a USB device, but MCU-Link is no longer detected.

Is there any way to recover it?"

HI @Maccha_Neko 

Which chip's FRDM development board are you currently using?

If you want to update your firmware.

1. Download the linkserver software and install it.

Search | NXP Semiconductors

2. Enter the ISP mode.

3. 

Double click the program_CMSIS.cmd

And press enter.

I appologize for the late reply.
I'm using FRDM-MCXN947.
I tried it according to your instructions, it was successful.
The FRDM board works well again.
I appreciate your help.
