RPi Pico board datasheet, contains Pico board schematic:

Some Zephyr documentation on RPi Pico board, couple version of Zephyr RTOS:

• Zephyr 3.1.0 . . . https://docs.zephyrproject.org/3.1.0/boards/arm/rpi_pico/doc/index.html

• Zephyr 3.4.0 . . . https://docs.zephyrproject.org/3.4.0/boards/arm/rpi_pico/doc/index.html

• Zephyr latest . . . https://docs.zephyrproject.org/latest/boards/raspberrypi/rpi_pico/doc/index.html

Note how supported peripherals list grows across these three releases. RPI Pico board support relatively new in Zephyr in 2022.

Special fork of `openocd` which can be used to flash and to debug RPi Pico via SWD interface . . . but what would the physical device and connection be from PC to RPi Pico SWD pins?
