连接ESP32与SD卡时遇到"SD mount failed"错误可能是因为硬件连接问题、SD卡异常、库配置错误、电源供应不足等原因。解决方法包括检查硬件连接，确认SD卡正常，检查库的支持和配置，确保正确的电源供应，检查SD卡是否被格式化，查看串口输出以获取更多信息。尝试升级或更改SD卡库、检查初始化时序、设置适当的SPI时钟速率...

I am getting an error that the sd card cant be mounted when the ESP32 comes out of deep sleep. The board is coded to wake up on a timer from deep sleep and mount the sd card and take a picture. My question is how can I get the SD card to mount properly? I am providing 3volt...

SD_Test中有非常详细的API方法,运行一下看看现象: /* * Connect the SD card to the following pins: * * SD Card | ESP32 * D2 - * D3 SS * CMD MOSI * VSS GND * VDD 3.3V * CLK SCK * VSS GND * D0 MISO * D1 - */
