The RP2350 microcontroller, utilized in devices like the Raspberry Pi Pico 2 W, features capabilities for dual instruction set architectures (ARM and RISC-V) on a single die. There is ongoing discussion about its support and recent updates from probe-rs and the architectural design of the processor that raises questions about efficiency and performance. Additionally, community feedback highlights a particular variant used in the Raspberry Pi Pico 2 W and the implications of utilizing Rust programming to leverage its features in embedded systems. A mention of a prior post sparks further inquiry on the implications of its architecture, with some uncertainty around the nature of dual CPU functionality.
