uf2-util is a small utility for generating .uf2 files. This program was designed specifically for the rp2040
and as such it assumes you have two separate binaries. A bootloader that is around 252 bytes, and then some
much larger third-stage binary.
It will automatically calculate and incorporate the bootloader crc checksum into the generated uf2.
Use the cargo package manager to install uf2-util.
cargo install uf2-utiluf2-util --bootrom bootloader.bin --progdata app.bin --out app.uf2Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
