MiSTer Real Time Clock (RTC) Addon Installation Guide
The DE10-Nano board does not include an on board hardware clock, The MiSTer software can with internet access via a WiFi or Ethernet connection set the time using NTP (Network Time Protocol) servers. However using a hardware real time clock (RTC) addon module allows the MiSTer to maintain real world time without internet access and even when the main power to your MiSTer is switched off.
Plugging in the Real Time Clock board is easy, it is always best to turn the MiSTer off before plugging anything into the DE10-Nano board. Now plug the RTC board into your DE10-Nano’s LTC connector, the LTC connector is highlighted in the image below. The RTC addon should be installed facing inwards towards the DE10-Nano.
The Real Time Clock board should easily plug into the LTC connector with a very small amount of insertion pressure, you certainly should not have to cut away or modify the plastic socket surrounding the LTC connector on the DE10 Nano board to allow for the installation of an RTC module.
Setting up the RTC to get real time saved is automatic and is just a matter of connecting the MiSTer to the internet and then leave it once booted up on the main menu core screen for around 15 minutes. This will automatically set and save the real time to the addon RTC module.
The real time can also be manually updated and stored using the Linux terminal / command line interface on MiSTer, the MiSTer will still require an internet connection to update the time manually. Access the terminal / command line by pressing F9 on the keyboard, the default MiSTer login uses root as the username and 1 as the password.
Then enter the following command and then press enter on the keyboard:
hwclock -wu
This should now store the systems current date time to RTC board. Next enter the below command and press enter on the keyboard, this will read back the date time stored on the RTC board to the command prompt.
hwclock -u
The date and time should now be set and always displayed in the main menu core, even when the MiSTer has no internet connection.
