Conexio Stratus Board Definition Files

Before we can compile and flash the application firmware to the Stratus device, we need to gather a few files for this board. First, we need to install the board definition files or the board’s devicetree in the ZephyrRTOS. Zephyr utilizes devicetree to describe the hardware available on its supported Boards, as well as that hardware’s initial configuration. An introduction to the devicetree is well documented here.

Step 1: Fetching Conexio Stratus Pro Board Definition Files

Stratus Pro

Stratus developers are asked to directly download the board files in zip format below extract/unzip, and copy the conexio_stratus_pro folder and place it in the NCS directory:

Option 1: Device Tree for nRF SDK v2.6.0

ncs/v2.6.0/zephyr/boards/arm

14KB

conexio_stratus_pro.zip

Conexio Stratus Pro Board Definition Files for v2.6.0

You should now see a folder named conexio_stratus_pro among other supported board files. Using the board target as conexio_stratus_pro_ns you can build Zephyr applications for the Stratus Pro board in non-secure mode.

Step 2: Patch MCUBoot file for Stratus Pro Board

Stratus Pro uses MCUBOOT as the main bootloader to properly execute and bootup applications. Download the conexio_stratus_pro.conf file below and place it in the following directory of the NCS:

ncs/v2.6.0/bootloader/mcuboot/boot/zephyr/boards
