# Raspberry Pi RP2350 Pico SDK Examples - Early Access

## RP2350 Instructions

Everything below this section is from the stock pico-examples, so ignore URLs etc., but generally instructions are the same.

The Pico SDK default continues to be to build for RP2040 (PICO_PLATFORM=rp2040), so to build for RP2350, you need to pass
By default, the Pico SDK targets builds for RP2040 (PICO_PLATFORM=rp2040). To build for RP2350 instead, pass

Is it worth mentioning that you can also use e.g. -DPICO_BOARD=pico2 or -DPICO_BOARD=pico2_w and that will "automagically" select RP2350 for you?

`-DPICO_PLATFORM=rp2350` to CMake (or `-DPICO_PLATFORM=rp2350-riscv` for RISC-V).

Most, but not all examples, currently work on RP2350 however you should be able to do a full build with any of the above platforms (PICO_PLATFORM=host however currently fails on some examples)

For RISC-V compilation, you should take a compiler from here: https://www.embecosm.com/resources/tool-chain-downloads/#riscv-stable
