Software Features

Pin muxing

Most of the Arietta lines on J3 can be configured for additional functions using the muxing cabability of the Atmel MPU. The default configuration depends from the at91-arietta.dtb file stored on the first micro SD partition and used at startup by the Linux Kernel.

The Arietta dynamic pinout page may helps you to understand what are the available peripherals and how to generate this file.
