📺 Raspberry Pi Pico RP2350 - Massive Performance Boost Trick

This video explores the performance differences between Cortex-M33 and RISC-V Hazard 3 cores on the 🍓 RP 2350 microcontroller. Initially, the RISC-V cores were surprisingly slower than expected due to using suboptimal compiler setups on Windows with 👩‍💻 Visual Studio Code. Feedback from the core designer revealed that the default toolchains lacked important optimizations, especially for floating-point operations.

By switching to 👩‍💻 Linux and manually configuring the toolchain and compilers, significant performance improvements were achieved. The optimized setup showed the RISC-V cores outperforming Cortex-M0 cores and, in some cases, even matching or exceeding the Cortex-M33. The video concludes that to fully unlock the RP 2350's potential, developers should use the right compiler and setup, ideally on Linux, for the best performance.
