5.4.3. LIBRSU Library

The RSU library offers a complete set of RSU APIs which are callable from your applications. The library is built on top of the Intel® RSU driver and it uses the Linux* MTD framework to access the QSPI flash.

The LIBRSU Library uses the term “slot” to refer to a sub-partition which is intended to contain an application image. It also uses the term “priority” to refer to the fact that the images are loaded by SDM in the order defined by the configuration pointer block.

For information about LIBRSU configuration file, data types, and APIs, refer to the LIBRSU Reference Information section.
