I try to build and run a "blinky" example for nRF52840 DK and nRF5340 PDK. And in the case of nRF52840 DK everything works properly. I connected to the boards and saw UART output:
*** Booting Zephyr OS build v2.3.0-rc1-ncs1 ***
But in the case of nRF5340 PDK I saw permanently the same repeated message:
*** Booting Zephyr OS build v2.3.0-rc1-ncs1 *** Flash regions Domain Permissions 00 01 0x00000 0x08000 Secure rwxl 02 63 0x08000 0x100000 Non-Secure rwxl Non-secure callable region 0 placed in flash region 1 with size 32.

Can you say what the difference is between running the same program on nRF52840 DK and nRF5340 PDK? Why doesn't it work properly in the case os nRF5340 PDK and what should I change to fix it?
