Please read this: [https://uavcan.org/Specification/6.\_Application\_level\_functions/#firmware-update](https://uavcan.org/Specification/6._Application_level_functions/#firmware-update)

Also this: [https://uavcan.org/Implementations/Libuavcan/Tutorials/11.\_Firmware\_update/](https://uavcan.org/Implementations/Libuavcan/Tutorials/11._Firmware_update/) The tutorial is for libuavcan, not libcanard, but the general principles are the same so you can use it as a high-level reference.

The Kocherga protocol module implements the UAVCAN bootloader protocol: [https://github.com/Zubax/kocherga/blob/master/kocherga\_uavcan.hpp](https://github.com/Zubax/kocherga/blob/master/kocherga_uavcan.hpp) (and it is built on Libcanard!)
