This is a production-ready software stack for Arasan’s SD 3.0/ SDIO 3.0/ eMMC 4.51 Host Controller IP that is used to connect to SD, SDIO, or eMMC devices.
The SD 3.0/eMMC 4.51 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 layer 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 SD 3.0/eMMC 4.51 software stack includes functions for initialization, sending of commands, data transfer, power management, SDIO interrupt handling, 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 SD 3.0/eMMC 4.51 software stack complies with the latest SD, MMC and SDIO standards. It supports SD and eMMC cards with the option for a device to boot directly from these cards using the boot mode feature.
