NRF5340-DK/ peripheral_uart

I've just received a new NRF5340-DK and am trying to compile and test the 'peripheral_uart' sample.

I'm using SDK 1.50.

When I loaded it into Segger via "Open NRF connect SDK Project" I specified the board as "NRF5340DF-NRF5340_CPUAPP"

I build the program via "Build Solution" in the segger drop-down list.

It compiles fine. When I start it (via Debug) the COM port displays  "*** Booting Zephyr OS build v2.4.99-ncs1  ***". The board does not display the blinking LED that says it's advertising.

I am able to build and run 'blinky'.

I am able to build and run the same application on my NRF52840DK. Note that when I did this I had to load the S140 soft device onto the board. I could not find a NRF53 equivalent to the soft device.

I'm sure that I'm doing something stupid - I just don't know what it is.
