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. The &os; driver is + implemented as an extension to the existing MMC bus, adding a + lot of new SDIO-specific bus methods. 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. Migration of the MMC stack to the new locking + model is necessary in order to work with SDIO cards effectively. + The &os; CAM implementation is believed to be a good choice. + There is an ongoing work to implement an MMC transport for + CAM.

+ + + + SDIO stack: finish CAM migration. The XPT layer is almost + ready, what is missing is a SIM module, for which a modified + version of SDHCI controller driver will be used, and a + peripheral module, where porting the mmcsd(4) driver is + required. + + Marvell SDIO WiFi: connect it to the &os; network stack, + write the code to implement required functions, such as sending + and receiving data, network scanning and so on. + +
