Pico SDK Prebuilt UF2s

This repository is used to provide pre-built UF2s of some of the universal Pico Examples. The available UF2s are:

• blink_universal.uf2 - Blinks the LED on Pico-series and Pico W-series boards
• nuke_universal.uf2 - Erases the Flash on any RP-series microcontroller based boards. On Pico-series boards this will flash the LED when finished, and then on all boards it will reset back to BOOTSEL mode.
• hello_universal.uf2 - Prints "Hello, world!" over USB and UART (using GPIO0 for UART TX, with baudrate 115200). On RP2350 based boards, it reboots between Arm and Risc-V architectures every 10s.

These can be dragged & dropped onto any RP2-series microcontroller based board, although the LED will only work on boards with the same LED GPIO as the Pico-series boards (GPIO 25).

Building

The UF2s are built by .github/workflows/build.yml, using the same Arm and RISC-V toolchains, picotool, pioasm, CMake and ninja the Pico VS Code extension uses for a given SDK version.
