Thanks, it seemed that my custom_board.h had a few unintended UART descriptions. Removed all UART lines. However I never used UART in my project which is strange.

Hi Tim

This post deals with the same error code as you. Please have a look.

Best regards,

Simon

Okay the implementation is done, but not working completely. When I start up the device, I check if something is written to the flash and copy those values to the RAM. Then the code reaches a loop where it waits for an event. However after a random time the controller generates a NRF_BREAKPOINT_COND. Error ID: 0x00004001

Without the flash functions it works great. The software has been tested in a different project on the dev kit and I do not get the error over there.

Thanks, currently rewriting my code to implement this!

EDIT: as this might be useful for other users, the example uses the command line interface. A lot of info can be found in the cli.c file.

Hi Tim

Have you looked at the fstorage functions? They provide read, write and erase functions without the need of the SoftDevice. The flash_fstorage example in the SDK should be helpful.

Best regards,
