This is a timeout while waiting for data from from the SD. It is at one of three places in the RP2040 SDIO driver. ``` libraries\SdFat\src\SdCard\Rp2040Sdio\PioSdioCard.cpp (3 hits) Line 385:...

I suspect that using the high bit of ax for the overrun flag is causing the problem. I wrote this example many years ago and needed to save memory so...

What happens if you run the [QuickStart](https://github.com/greiman/SdFat/blob/master/examples/QuickStart/QuickStart.ino) example?

Try the following. ``` #define SD_MISO 2 #define SD_MOSI 15 #define SD_SCLK 14 #define SD_CS 13 SPIClass sdSPI(VSPI); #define SD_CONFIG SdSpiConfig(SD_CS, USER_SPI_BEGIN | SHARED_SPI, SD_SCK_MHZ(10), &sdSPI) ... sdSPI.begin(SD_SCLK, SD_MISO, SD_MOSI,...

I did compile the following. But can't test it. ``` #include "SdFat.h" SdFat SD; #define SD_MISO 2 #define SD_MOSI 15 #define SD_SCLK 14 #define SD_CS 13 SPIClass sdSPI(VSPI); #define SD_CONFIG...
