Linux

The Nao uses a Linux 5.4 real time kernel for intel processors (linux-intel/preempt-rt).

Most of the kernel configuration is done by the meta-intel layer for yocto. Special modifications for the Nao robot are contained in the meta-nao layer and mainly consist of patches and kernel modules by aldebaran for chestboard communication.
