Hi, I have B-U585I-IOT02A board. I'd like to log data to an uSD card. Is it possible to connect external SD Card reader along with FATFS ? If so, which protocol to use SPI or MMC and which physical ports? I don't use onboard: gyroscope, magnetometer, lcd interface, touchscreen interface.

One could perhaps check schematic vs data sheet to see if you've got any hope of exposing the SDMMC interfaces.
SPI should at least be exposed on the Arduino rails.
