I am no longer adding custom drivers. There are now hundreds of "Arduino like boards".
SdFat version 2.x probably will fail with a compile error for LGT8F328P if USE_STANDARD_SPI_LIBRARY is zero.

I don't have this hardware so you must solve this problem.
from sdfat-beta.
As per (dbuezas/lgt8fx#24)
The SPI of LGT8F328P has more features than ATmega328P SPI. One of these features is 4 byte input and 4 byte output buffer. (Translated databook v1.0.5 page 195: -Input/output both have 4 buffer register.) If your SD card library not handling this buffer, SPI will not work as expected. Maybe your SD card library could use the SPI library from this lgt8f package.
But if your SD card library use hardware SPI, it won't work.
For SdFat v1.x (I haven't played with the 2.x series), In SdFarConfig.h (Arduino/libraries/sdfat), set:
#define USE_STANDARD_SPI_LIBRARY 1
As per the comments:
* If the symbol USE_STANDARD_SPI_LIBRARY is zero, an optimized custom SPI
* driver is used if it exists. If the symbol USE_STANDARD_SPI_LIBRARY is
* one, the standard Arduino SPI.h library is used with SPI. If the symbol
* USE_STANDARD_SPI_LIBRARY is two, the SPI port can be selected with the
* constructors SdFat(SPIClass* spiPort) and SdFatEX(SPIClass* spiPort).
... works great then. Software SPI also works (see the rest of the comments and examples included w/SdFat)
