Hi, i'm finish to test FATFS and when I execute command

fresult = f_write(&Fil, "teste escrita realizado com sucesso \r\n", 35 ,&bw);

The fresult return:: FR_INVALID_OBJECT : The file/directory object is invalid or a null pointer is given.

Why is this happen? Someone can help me ?

Glad you solved - yet much good would result if you'd detail your "fix." (many would have responded - your post provided little code or detail - making that difficult)

Did you "cure" with early use of FOpen (or similar) function - which was absent when you earlier received unwanted result? Thanks...
