HI
目前我司在使用TI的AM3352芯片时，在调试sdio WIFI时，使用mmc3的sdio连接的AP6256。当sdio数据线使用，GPIO1-17,GPIO1-18,GPIO1-19,GPIO1-28这一组时SDIO始终异常，当SDIO数据线使用gpio1-12,goio1-13,gpio1-14,gpio1-15时SDIO就通信正常，wifi也可以正常使用。为了调试我把GPIO1-17,GPIO1-18,GPIO1-19,GPIO1-28这一组配置为普通GPIO,然后去拉高拉低引脚，目前只有GPIO1-28可以正常拉高拉低。感觉GPIO1-17,GPIO1-18,GPIO1-19这三个脚没有正常工作。目前调试没有什么进展，希望公司工程师能够给与指导。现附上设备树配置。谢谢！
