This is a flash algorithm for the RP2040 and RP2350 chips, 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 to install the requirements:
cargo install cargo-binutils
The rust-toolchain file will get you the targets and components you need.
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 and RP2350.
