STM32F439 Development Board Data Corruption Issue

pankaj4 · ‎2025-04-22

Hi,

I am working on the STM32F439 development board. I am creating a test.csv file and logging data using FATFS on an SDIO SD card. I can view the data through USB MSC on a Windows PC. However, when I open the file in .csv format or edit some data from the PC, and then reconnect the board to the PC, the data gets corrupted or changes.

Does anyone know about this problem? If so, please help me.

Thank you!

Best regards,

Pankaj
