Unable to debug because my MCUXpresso is showing no probes are available!

[Koushik278-008]

I connected my PC to the FRDM-MCXN947 Microcontroller I, installed the SDK files, and imported a program to my MCUXpresso IDE. After I Start debugging it shows that no Compatible probes are available. This is my first day with MCUXpresso and I am having this issue! What do you think I should do to do this project successfully?

It would be good to check the followings:

• make sure your PC is connected to the FRDM-MCXN947 MCU-Link USB port (J17)

• the MCU-Link probe is detected by your OS. The probe is shown in "Bluetooth & other devices". Example:

• retry debug after using the "Clean Up Debug" button

• try "LinkServer -l5 probes" to list the probes. Example:

My PC is connected to the FRDM-MCXN947 MCU Link - (J17) Port. And as it was said in the website the LED was blinking. But I can't find the device in my bluetooth!

Hi @Koushik278-008

I'm not sure what might be the problem.

Other things to try:

• try to connect the board to a different USB port of your PC, without using a USB hub
• try to connect the board with SWD disabled (J19 installed), then reconnect it with SWD enabled (J19 removed)
• try LinkServer command line tool to list the probes. Example: c:\NXP\LinkServer_1.6.133\LinkServer.exe -l5 probes
• check the probe status LED (D11): it should pulse slowly if the CMSIS-DAP firmware is running properly
• check the probe USB COMM LED (D10): it should stay on

Also, you could try to (re)program the MCU-Link firmware (CMSIS-DAP or J-Link):

• put the probe in ISP mode (jumper J21)
• open a command prompt, change directory to "c:\NXP\LinkServer_1.6.133\MCU-LINK_installer\scripts" (or use the path to LinkServer \ MCU-Link installer version you have on your PC) and run program_CMSIS.cmd or program_JLINK.cmd
• remove the ISP jumper (J21)
