Overview

We designed and developed a solution to integrate Secure – AWS Wi-Fi EVK with the latest Zephyr along with TF-M integration support. TF-M integration enables “Non-Secured” Zephyr applications(running on the M4 core) to interact with TF-M secure binary (running on the M0 core) using PSA APIs. In addition to that, there is necessary BSP SW porting/development required to execute a minimum demonstration of the EVK TF-M example for the Zephyr platform. Our firmware engineers prepare a minimal BSP having the support of modules TRUSTED_EXECUTION_NONSECURE, ARM_TRUSTZONE_M, ARM_MPU,CONSOLE ,UART_CONSOLE ,SERIAL,GPIO, WiFi, I2C, Counter, Timers, etc. Our QA team carried out testing of the entire integration by exercising all available sample examples of the Zephyr Repository. We executed the necessary changes/fixing and captured all the successful execution logs in the final delivery document.
