A Slice of Zephyr Pi!
summary
Zephyr now runs on RP2040 and RP2350 boards (Pico, Pico W, Pico 2, Pico2W) with community landings that show merge waits from weeks to nearly a year and PRs with hundreds of comments; networking tests show Zephyr's zperf is noticeably slower than the Pico SDK but recent Kconfig tweaks improve throughput. Tooling requires a forked OpenOCD for some boards and the official debug probe works for single‑USB flashing; PIO drivers provide virtual UART/SPI, Rust and RISC‑V builds are emerging, secure boot ships for ARM only, and low‑power modes hit ~50 microamps on RP2350; demos are mixed but functional.
