SDIO is an interface designed as an extension for 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, barcode scanners. The 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 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. There is an + ongoing work to design a good locking model for the stack. WiFi + driver is able to load a firmware onto the card and initialize + it.

+ + + + SDIO stack: Design a locking model, define how the + interrupts should be processed (on SDIO controller level, MMC + stack level and by child drivers). + + Marvell SDIO WiFi: connect to the &os; network stack, write + the code to implement required functions (such as sending and + receiving data, network scanning, and so on). + + Implement detach path. It cannot be tested on the DreamPlug + used for development, because it does not have an external + SDIO-capable slot. + +
