Introduction

sdo-client-sdk is a portable implementation of the Secure Device Onboarding (SDO) protocol. This component is portable across multiple environments, including to various microprocessors (MPUs) and microcontrollers (MCUs).

At present, sdo-client-sdk is tested to following platforms showcasing SDO capabilities:

  1. Linux* x86 machine (with Ubuntu* OS version 20.04): Reference implementation
  2. NUCLEO-F429ZI STM32 Nucleo* development board running STM32F429ZI Arm* Cortex*-M4 MCU over Arm* Mbed* OS.
  3. NUCLEO-F767ZI STM32 Nucleo-144 development board running STM32F767ZI Arm Cortex-M7 MCU over ARM Mbed OS.
  4. WaRP7 WaRP7 development board running i.MX 7Solo Arm Cortex-A7 MPU over ARM Mbed Linux OS.

Other linux platfoms Raspberrian, yocto based build for different platforms(A7) can be used for SDO build also.

The SDK is to be linked with a customer application that initiates and drives the onboarding functionality. The SDK comes with a sample application that demonstrates how to onboard. The SDK also contains required documentations and an API guide.

The sdo-client-sdk is organized according to the following directory structure:
