Not able to run a simple blinky application on nrf5340DK with zephyr

[Pelle]

Hi

I'm evaluating the nrf5340dk devboard and are building a simple application on top of zephyr. I'm using Cmake and ninja on Ubuntu. The code builds and I'm able to flash the board, but nothing happens with the LED.
I've commented out MCUboot from config file to just build and flash the application.

When I look at the .hex file there is an offset of 0x200, not sure if that's correct or something wrong with the build system.
IMO the start address of the code should be at 0x0000 0000 when no bootloader is used. 
Could that be the issue that the reset vector is located at wrong address? How to change that in the configuration?

Hi,

Are you building an existing application or sample from nRF Connect SDK or Zephyr, or is this an application you have made yourself? There is a simple Blinky example in Zephyr, but that does not use MCUboot.

Do you see the same if you build and flash with west instead?

Please check out Working with nRF5340 DK in our documentation for more information on how to use nRF5340 DK.

Best regards,

Marte

Hi
Thanks for your reply!

Sorry forgot to update, but the issue is solved. It was the offset 0x200 that was the problem. When removing that from the config file it worked.

I'm building an own simple application.
