ZView, a Zephyr RTOS runtime visualizer
Real-time system observability for Zephyr RTOS, delivered over SWD.
Stop guessing your stack margins and heap health. ZView provides a zero-footprint, high-fidelity visualization of your Zephyr application's runtime, delivered over SWD with zero instrumentation.
No UART, no RTT, and no manual code changes. Just Kconfig and your probe.
This page covers the standalone pip installation. Everything else, including using ZView from a west workspace, is in the main documentation.
Installation
pip install zview
Or from the root of the repository:
pip install .
Prerequisites
Any Zephyr build works, and a few Kconfig options add to what ZView can show. The zview snippet that sets them ships with the west module, not with the pip package, so set them in your prj.conf as listed in the prerequisites.
How to Use
# ELF, runner and target read from the build directory
zview -d build
# Or passed explicitly, e.g. nRF5340 DK via JLink
zview -e build/zephyr/zephyr.elf -r jlink -t nRF5340_xxAA
zview --help and zview <command> --help list every command and argument. The main documentation covers what each one does, how to pick -t for your runner, navigation, and offline recording and replay.
