ArduPilot bootloader. This implements the same protocol originally
|
|
developed for PX4, but builds on top of the ChibiOS HAL
|
|
|
|
It does not use the full AP_HAL API in order to keep the firmware
|
|
size below the maximum of 16kByte required for F4 based
|
|
boards. Instead it uses the ChibiOS APIs directly
