基于ARM的SDIO驱动设计

ARM-based Driver Design for SDIO

在介绍了基于ARM的ark1600芯片和SDIO的特点、内部结构、工作模式、命令与响应之后分析了SDIO的驱动的主要内容、初始化过程和需要获取的卡上信息,说明如何进行寄存器读写和配置。该驱动适用于所有SDIO的通用层部分,在arkmicro公司的ark芯片SOPC验证平台上成功初始化了Toshiba的Type-B蓝牙SDIO卡,获取了该卡的信息,并对其进行了功能上的配置。

This paper introduces ark 1600 chip basing on ARM and SDIO＇s features,internal structure,operating mode, command and response, then analyses the frame of SDIO＇s driver, the information on the card, and tells how to use the new IO command to read from or write into the registers. The driver applies for the SDIO layer of all kinds of SDIO cards and has successfully initialed Toshiba＇s Type-B bluetooth SDIO card on the SOPC platform of ark chip designed by arkmicro CO. Ltd.
