Hi Vincenzo,
Please refer to the TivaWare Utility library where you will find API to support SPI flash.
Below is an excerpt of the features. See the SPIFlashQuadRead() to read the SPI flash in Quad-mode. I assume the microSD you are interfacing with will support Quad SPI mode.
This below post may also help where Bob mentioned about the performance bottleneck on the Quad-mode. The post is lengthy. You will need to go to the end of the post for Bob's analysis.
