time stamp in new file of sd card

Hello Siva

What is the reference you are using for time stamps?

do we have internal RTC in tiva series?

if  not present internally  do we have any other source for getting time stamp ?

which part of the structure should i update for fat file system to get actual time and date?

Hello Siva

Yes there is a RTC in Tiva but it requires the use of a 32K oscillator. To update the time stamp on a file the function call is f_utime

Do u have  any example code for generating time stamp from RTC second counter.

IS  back up battery and 32 khz clock  mandatory for RTC to run contionously?

does the RTC run in hibernation mode or alwayS?

Hello Siva,

No there is no code example for the same.

The back up battery is required if you plan to use Hibernate VDD3OFF Mode. The 32K clock is required. The RTC runs as long as it is enabled and is not dependent on the fact that hibernate mode needs to be enabled
