The same on my side. When I first start the command line tool jlink I can see the device as above. then exit the tool and open the debugger view in Keil. then I can see the cpu in the swd chain.

However burning does not work.

I tried not with the command line tool and all my 51422 devices does not work. Only the 51822 does work. This looks strange to me. I already downloaded the latest segger jlink firmware.
