This is a flash algorithm for the RP2040 chip, used in the Raspberry Pi Pico board. It implements the CMSIS-Pack ABI, so it's compatible with any tools that use it, including probe-rs.

Run the following requirements:

cargo install cargo-binutils && rustup component add llvm-tools-preview rust-src

Building requires nightly Rust.

Just run build.sh. It spits out the flash algo in the probe-rs YAML format:

flash-algo$ ./build.sh 
instructions: sLUUIACIGUoBRguI...wRwAgcEc=
pc_init: 0x00000000
pc_uninit: 0x0000007c
pc_program_page: 0x00000088
pc_erase_sector: 0x00000084
pc_erase_all: 0x00000080

The algo module contains the FlashAlgo trait, and an algo! macro to generate the glue functions for a given struct implementing it. This is generic for all chips, so feel free to reuse it!

main.rs has the actual implementation for RP2040.
