Adding ESP32/Xtensa Silicon and Custom Boards To PX4 - Henry Kotzé, AutonoSky

Friday October 9, 2026 14:00 - 14:20 CEST

South Hall 1 B (Floor 1)

This talk will introduce a new MCU architecture that PX4 only recently supported: the Xtensa ESP32. Using it as a walk-through, we'll demonstrate the software components needed to add your own custom board, contribute to or expand existing MCU architecture support, and highlight how PX4's compile process is designed to be agnostic to the underlying MCU architecture.

Some highlights will be:
How PX4 interacts with NuttX at a low level, and why that relationship is central to bringing up new hardware

The role of the High Resolution Timer (HRT) in PX4's timekeeping, and what it takes to implement it for a new architecture

The difference between Menuconfig and boardconfig, and when to use each when defining your board's peripherals and pin allocation

How PX4's build system sets up the compilation environment for NuttX, and how to configure it for your specific board

How PX4 is designed to be MCU-agnostic, and what that means in practice when working at the boundary between PX4 and NuttX
