how to setup time stamp on SD card

MNapi
Senior III

I do have RTC working and SD, I found this code

 FRESULT set_timestamp (char *obj)

   {

   FILINFO fno;

   HAL_RTC_GetTime(&hrtc, &sTime, RTC_FORMAT_BIN);

      HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN);

   int hour = sTime.Hours;

   int min = sTime.Minutes;

   int sec = sTime.Seconds;

   int month = sDate.Month;

   int mday = sDate.Date;

   int year = sDate.Year;

   year+=2000;

   fno.fdate = (WORD)(((year - 1980) << 9) | month << 5 | mday);

   fno.ftime = (WORD)(hour <<11 | min <<5 | sec/2 );

  f_utime(obj, &fno);

   }

but it keeps saying undefined symbol f_utime

I see that ff.c contain this function, I do not know what the problem is

Removed MPU tag, betting your not using those.

PLEASE always state the MODEL/FAMILY of MCU you're using in the TOP POST, it's not hard and conveys useful contextual information.

Check how you're building / configuring FatFS

Make sure you have clock info handled in DISKIO.C unpack a SysTick counter into human / calendar centric data, or use RTC, or whatever..
