Zephyr is a comprehensive ecosystem, but sometimes you want a better view of your system and end up reaching for shell, UART, printk, RTT, or tracing, all of which work, but all of which cost on-target code, pins, or configuration overhead, or even extra hardware. ZView is a live, non-intrusive, low-integration-cost runtime observability tool that provides an overview of how your application behaves (threads, heaps, allocation and fragmentation, CPU usage, and more) all in a TUI, using only your debug probe via SWD. It uses the debug access port to read kernel memory passively while the target keeps running. No instrumentation, no halt, no extra pins. ZView interprets what it reads, recognizing threads, heaps, and other kernel objects, turning raw memory into actionable runtime insights. This talk covers what ZView is, how it works, its limits, and where it can go next. The goal is to make ZView a standard part of the Zephyr debugging toolkit, with the community's help.
Paulo Santos is a Zephyr enthusiast, collaborator, and an embedded systems developer based in Brazil. Author of ZView and CLUTGen external west projects/modules.
