MCU-Link Pro is not being detected

[JamesH_Scion]

Hi everyone.

I have recently run into some troubles with my MCU-Link Pro (The exact package here: MCU-Link Pro).

When attempting to auto update the MCU-Link Pro with LinkServer CLI, the update failed part of the way through. Both LinkServer CLI and MCUXpresso IDE can no longer detect the debugger when it is both in and out of ISP mode. This means that I cannot upload a repaired firmware to it.

I have tried to connect to it with two different Windows 11 machines, with two different working micro-USB cables. I have followed the correct procedures to put it into ISP mode, and the red LED next to the J4 jumper stays lit.

My Windows machines play a sound to indicate that the MCU-Link Pro has either been plugged-in or removed from the USB.

Thank you for your help.

Hello,

Same issue here with my MCU-Link Pro. I tried upgrading it using MCUXpresso IDE v24.12 with LinkServer v25.3.31, but the upgrade failed, and since then the device is no longer detected at all.

With the probe in ISP mode attached, the CMSIS-DAP update script give me this

Thanks in advance for your help!

Hello @JamesH_Scion 

Please try to manually update the firmware.

If the issue persists, please take a video or capture screenshots to show all the steps you've taken. Additionally, please connect to another PC using a different USB cable for testing.
