STM32G474RE-Eval microSD support

My design requires a microSD with the G474RE MCU.  The Eval board schematic shows the design and some code in the \driver\BSP.  However, I do not see the application example.  My requirements are to read and write multiple data files.  Where can I find an example with these features?  Any other eval examples I can port over?

Hello,

You can refer to this example located in the STM32G4 Cube HAL package:

https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Applications/FatFs/FatFs_uSD_Standalone

The folder to look at is “Application” and not “Examples”
