Punchboot is a secure and fast bootloader for embedded systems. It is designed to:

• Boot as fast as possible
• Integrate with the SoC's secure boot functionality
• Authenticate the next piece of software in the boot chain
• Support A/B system partitions for atomic updates
• Support automatic rollbacks
• Minimize software download time in production
• Be useful for day-to-day development

Punchboot is designed for embedded systems and therefore it has a minimalistic apporach. There is no run-time configuration, everything is configured in the board files.

Punchboot could be useful if you care about the following:

• Boot speed
• Secure boot
• Downloading software quickly in production

Punchboot tools is the host tools used to interact with the punchboot bootloader. The punchboot tool is a CLI what works on both linux, windows and in the future macos.
