If you are using the Manually Save and Load Snapshot Image mode, there is no need to apply kernel patches. You can skip this section.

Linux® for MPU Source Code

The Linux® kernel for Microchip’s Atmel® AT91 SoCs, which are based on Arm® architecture, is maintained in a Git repository hosted on GitHub®. This repository is a fork of the official Linus Torvalds' git tree.

Our objective is to integrate all the AT91-related material in the official Linux kernel. Until this process is complete, the linux4microchip/linux GitHub website provides the Linux4SAM Linux kernel source tree for AT91 devices.
