Here's my code: FATFS fs; FRESULT fr = f_mount(&fs, (TCHAR*)"0:/", ( Writes of 512-byte are the least efficient on the SD-Card, it is a single sector, ideally you want to write a cluster to achieve maximum throughput on the FatFs and SDIO/SDMMC level. HOPE THIS HELPS! DON'T STOP TRYING! Exactly as you would on other platforms. After the reset program reads four files. The f_open() function has a FA_OPEN_APPEND flag, which makes subsequent f_write() functions to append data at the end of the file. Fatfs significant slow down in directories with many files.
