Building a Debug Probe with the Zephyr RTOS - Johann Fischer, PHYTEC Messtechnik GmbH, Germany

Sign up or log in to save this to your schedule and see who's attending!

Many of the Arm Cortex-M based development boards supported by the Zephyr RTOS have an on-board chip that acts as a debug probe. This is typically based on (or compatible with) the Arm Mbed DAPLink open source project. This provides the developer with several interfaces: USB MSD for drag-and-drop programming, USB CDC-ACM for console output and a USB HID-based debug channel. The DAPLink project uses the Keil RTX OS and requires the Keil or Arm compilers, which makes it impossible to build it on Linux based systems.

​The talk is about whether it would be possible (and how) to build a debug probe on top of the Zephyr RTOS. Zephyr already has a reasonably stable USB device stack with CDC-ACM and MSD support. The author will give a overview about the structure of debug probe software like DAPLInk, and the USB device stack in Zephyr. Furthermore, the author will introduce the implementation of the components and their interaction in Zephyr.
