Description
Was working in build from 6/2/2025 (Last time I flashed the device). Was going to add some new functionality so updated and SD Card stopped mounting:
++++ Exception System.Exception - CLR_E_VOLUME_NOT_FOUND (1) ++++ ++++ Message: ++++ nanoFramework.System.IO.FileSystem.SDCard::MountNative [IP: 0000] ++++ ++++ nanoFramework.System.IO.FileSystem.SDCard::Mount [IP: 0004] ++++ ++++ ESP32_S3_ALL_UART_SDCARDISSUE.Program::Main [IP: 000b] ++++
How to reproduce
Code that was working:
Configuration.SetPinFunction(Gpio.IO04, DeviceFunction.SDMMC1_COMMAND);
Configuration.SetPinFunction(Gpio.IO05, DeviceFunction.SDMMC1_CLOCK);
Configuration.SetPinFunction(Gpio.IO06, DeviceFunction.SDMMC1_D0);
// Boards with SDIO/MMC interface with 1 bit data lines ( e.g. ESP32 Olimex EVB , POE )
_SDCard = new SDCard(new SDCardMmcParameters { dataWidth = SDCard.SDDataWidth._1_bit }, new CardDetectParameters { autoMount = false, enableCardDetectPin = true, cardDetectedState = false, cardDetectPin = 46 });
try
{
_SDCard.Mount();
Debug.WriteLine("Card Mounted");
File.AppendAllText("D:\\sdcard.txt", "Hello from SD Card!");
string txt = File.ReadAllText("D:\\sdcard.txt");
Debug.WriteLine($"Read from SD Card: {txt}");
}
catch (Exception ex)
{
Debug.WriteLine($"Card failed to mount : {ex.Message}");
Debug.WriteLine($"IsMounted {_SDCard.IsMounted}");
}
Expected behaviour
Used to mount and allow file read and writes per code supplied (Exact code from project that was working)
