I'm having trouble getting the openSDA working on the tWR-K24F120M board.
I can see the openSDA port as COM6 in device manager, is there somewhere to enter the COM port number into KDS or does it find it automatically?
My setup is:
But I get this when going into debug:

And then this in the error window:

Error message from debugger back end:

What did I do wrong?

Hi Piotrek,
Before debug , you should update bootloader.
Enter bootloader Mode , then load J-Link Application.
Detail steps please refer to below :
And you only need refer to red box I log. the JLink driver i attached to you !
