Dear Tech support,


I tried to upgrade the debugging firmware from OPENSDA CDC to Jlink Open SDA .

I hold down SW2 and plug in the USB cable on J10/SDA port.

The PC see the the bootloader. 

I  tried all 3 different versions generic and one specific to KL26Z.

The files seems to upload just fine, but after unplugging and re-plugging the usb cable the PC/Teraterm/Device manager cannot find the Jlink debugger.

The debugger light does not blink either.


I need to change from OpenSDA-CDC to Jlink because MCUXpresso won't recognize OpenSDA-CDC.
