MCUXpresso doesn't connect to target

Ladies and Gentlemen,

I've got MCUXpresso 25.6 [Build 136] recently installed on my Linux Mint 22.1 Cinnamon machine.

I'm trying to get familiar with the development system and uC programming, too.

I connected an LPC11U37H LPCXpresso board (it is original from NXP, but was in the drawer for a few years). Also, I wrote a very primitive program, just trying to configure the microcontroller. (clocks, peripherals, etc)

When I try to debug my code, it builds without failure but MCUXpresso cannot connect to the debugger board:

However, if I close MCUXpresso and try to use LinkFlash 25.6.131 - it is automatically installed together with MCUXpresso - then I see, this SW connected to the probe with no issue:

My own code doesn't work yet - no surprise - but I could only debug it inside MCUXpresso.

Here's the output of LSUSB:

I have read this post from Helmut, but it didn't help:

Please give me advice, what shall I set to use this board?

Found a solution - after a few days of try-and-error:
Left side, in the project explorer window, right-click on the project name.
In the pop-up menu, select Debug As -> 2 MCUXpresso IDE Link Server (inc. CMSIS-DAP) probes.

And, voila! It works.
