Arduino Notes

Arduino code can be compiled to run. Please note that no support can or will be provided if your application runs Arduino code.

The following page comprises collective notes from individuals who have had had success getting Arduino code to run are listed as follows. At a high level, you'll need to package your code for the appropriate soft device, adjust the linker settings, then flash with nrfjprog.

Soft Device 7

Adjust linker settings:

FLASH (rx) : ORIGIN = 0x27000, LENGTH = 0xc9000 
RAM (rwx) :  ORIGIN = 0x20002280, LENGTH = 0x3dd80
uicr_bootloader_start_address (r) : ORIGIN = 0x00000FF8, LENGTH = 0x4

Packaging

nrfutil pkg generate --hw-version 52 --application-version 1 --application ~/application.hex --sd-req 0xCA --key-file /path/to/private.pem app_dfu_package.zip

Limitations

Arduino BLE won't work. Use another bootloader, or re-write your application with the nRF SDK.
