eMMC 5.1 Nex Bus Driver

eMMC 5.1 Nex Bus Driver is a production ready software stack for eMMC 5.1 Host Controller IP that is used to connect eMMC devices. The eMMC 5.1 stack can also be used for validating a device during its development and integration life cycles thereby helping designers to reduce the time to market for their product. The modular neX+ stack is architected to be OS and platform independent which eases porting effort. It has a thin OS and hardware abstraction layers making it highly portable. The neX+ stack provides a generic API set to access, control and configure the bus driver, host controller driver and the underlying hardware.

The eMMC 5.1 software stack include functions for initialization, sending of commands, data transfer, power management, bus configuration, client driver matching, host controller hardware configuration and shutdown. The neX+ stack can support a single host controller with multiple slots or multiple host controllers with multiple slots. The software stack complies with the latest eMMC standards. It supports eMMC cards with the option for a device to boot directly from these cards using the boot mode feature.
