WiFi and Secure Socket Offload in Zephyr

Explore WiFi and secure socket offload capabilities in the Zephyr operating system through this informative conference talk. Delve into the Zephyr WiFi offload architecture and learn about implementing a WiFi offload driver for the TI CC3220SF SoC. Discover how secure communication, secret storage, and encryption are handled by the offload chip. Gain insights into the Zephyr network stack, TCP/IP offload options, and the addition of TLS to socket APIs. Understand the process of establishing secure channels and provisioning certificates/keys to devices. Led by Gil Pitney from Texas Instruments, this presentation covers topics such as GPGPU on ARM, Neural Network Acceleration, and Zephyr WiFi offloading, drawing from his experience speaking at Linaro Connect conferences.
