Pico SDK Development

Read the shared embedded contract and keep source/build, device and physical evidence separate.

Read native SDK workflow. Confirm RP2040 versus RP2350, exact board, flash population, SDK revision, compiler and CMake cache. Arduino-Pico is a different framework; its core version is not the Pico SDK version. Preserve a requested CPU architecture and board profile.

Use an out-of-source build with the repository's PICO_BOARD, PICO_PLATFORM, SDK path and toolchain. Avoid changing a populated build directory to another chip or SDK; create a fresh build directory. Build the ELF before producing or copying a UF2. Keep map/ELF and SDK revision together.
