Section I: Hardware Customization
Before creating your customized hardware, we suggest you start with the Linux Hardware Design
Project available on
your board’s Digilent product webpage. The reference design includes the proper
configuration for most of the peripheral devices available on-board your product including the interrupt
controller, timer, clock generator, AXI interconnects, etc. that are all essential for Linux to operate
properly.
