I'm working on a custom board with an STM32L476ZGT6 and set up code through the STM32CubeMX utility and followed along with the sample code for the eval board. I want to be able to copy files to the SD card when I connect my device and am able to get the connection and move the file to the SD Card and it will show up as being completed, however once I disconnect the device I lose the file. I've traced through the code and I do all the writes successfully, I just can't seem to save the file there once I unplug my device, any help would be greatly appreciated.
