[components] sdio driver

Open mxgsgtc opened this issue 3 years ago • 0 comments

mmcsd_detect 函数在检测 sdio设备不成功时,也需要向 mmcsd_hotpluge_mb这个 mailbox反信。

■需求 代码实现是: SD卡的插拔检测有一个thread,thread会loop 读取SD卡探测用的gpio,如果gpio值为1,则认为插入SD卡了,紧接着 调用 mmcsd_change 函数通知mmcsd_core,进行SD初始化。

■bug现象 插入SD卡后, 执行流: mmcsd_change(driver中调用) → mmcsd_detect(组件 sdio) 当执行到:mmcsd_detect的mmcsd_send_app_op_cond 函数时拔卡的话, 会造成此此函数执行错误,此时mmcsd_detect函数就不会发rt_mb_send 导致mmcsd_change 卡住 。 这样的话,在插入SD卡时,就无法执行mmcsd_change 了。
