Pico Boot2 File Generator

Description

This tool generates the Boot2 stage for all flash chips known in a database for a Pico.

These files can e.g. be used to support new combination of a Pico with a new flash chip.

Refer https://github.com/earlephilhower/arduino-pico/tree/master/boot2.

Usage

Prerequisites: Python 3 and arm-none-eabi-gcc toolchain in the path.

You can also use the already pregenerated files in generates/.

These were generated using arm-none-eabi-gcc 10.2.1 (Q4 Major).
