Software Workflow

To create software for an SoC partial reconfiguration design, you create a device tree overlay that describes the static portion of your design (the base revision). Then, you create device tree overlays for personas in each PR region.

In this application note, you create and run a PR software example based on the GHRD. You start with a base device tree for the SoC, distributed with your kernel. Then you carry out steps to adapt this device tree to the PR example design.
