SDIO is an interface designed as an extension of the existing + SD card standard, to allow connecting different peripherals to + the host with the standard SD controller. Peripherals + currently sold at the general market include WLAN/BT modules, + cameras, fingerprint readers, and barcode scanners. + Additionally SDIO is used to connect some peripherals in + products like Chromebooks and Wandboard. A prototype of the + driver for the Marvell SDIO WLAN/BT (Avastar 88W8787) module + is also being developed, using the existing Linux driver as + the reference.

+ +

SDIO card detection and initialization already work, most + needed bus methods are implemented and tested.

+ +

WiFi driver is able to load a firmware onto the card and + initialize it. A rewrite of the MMC stack as a transport + layer for CAM framework is in progress. This will allow to + utilize the well-tested CAM locking model and debug features.

+ + + + SDIO stack: finish CAM migration. The initialization of + MMC/SD card is implemented in the XPT layer, but cannot be + tested with the real hardware because of lack of any device + drivers that implement peripheral drivers and SIMs for CAM + MMC. The plan is to use a modified version of BeagleBone Black + SDHCI controller driver for SIM and a modified version of + mmcsd(4) as a peripheral driver. + + Marvell SDIO WiFi: connect to the &os; network stack, + write the code to implement required functions (such as + sending/receiving data, network scanning and so on). + +
