SdFat SdSpiCard error

Other Hardware Storage

I am using the Adafruit Feather M0 adalogger to log I2C sensor data using a sketch modified from the SdFat datalogger sketch. The sketch worked fine previously on the Adafruit 32u4 adalogger but gives the following error now. Any suggestions?

Arduino: 1.6.5 (Windows 8.1), Board: "Adafruit Feather M0 (Native USB Port)"

Edit libraries\SdFat\SdFatConfig.h and change line 81 to read;

#define SD_SPI_CONFIGURATION 1

If SD_SPI_CONFIGURATION is defined to be one, SdFat uses the standard Arduino SPI.h library, as opposed to the custom implementation within the SdFat library.
