I created a text file using Notepad in windows 7 and saved to a sd dard. I plug this ds card into my company's FX3S based board. I can read back this file using FX3SFileSystem sample code. But after I write a file to the sd card, this card become unaccessable. I got FR_NO_FILESYSTEM error when I read back the file. Please give me help.
Please share the detailed steps on how you created a file from the UART console.
