Building a Debug Probe with the Zephyr RTOS

Linux Foundation via YouTube

Overview

Explore the process of constructing a debug probe using the Zephyr RTOS in this informative conference talk. Delve into the challenges of creating an alternative to the ARM Mbed DAPLink open source project, which is typically used in Arm Cortex-M based development boards. Learn about the key components of a debug probe, including USB MSD for drag-and-drop programming, USB CDC-ACM for console output, and CMSIS-DAP based debug channel over USB HID. Discover the limitations of the DAPLink project's reliance on Keil RTX OS and proprietary compilers, and understand how Zephyr RTOS can provide a Linux-compatible solution. Gain insights into the structure of a debug probe, Host Interface Circuit, and Serial Wire and SWD protocols. Examine the implementation of CMSIS-DAP in Zephyr RTOS and explore the possibilities it offers for building versatile debug probes on open-source platforms.
