- The RTC plugs into the 14-pin LTC header on the DE10-Nano and does not require an I/O board.
- An RTC board having a metal battery holder is the safest and easiest to fit if you’re using an I/O board.
- Please do not use an RTC that might cause a short circuit on the DE10-Nano or MiSTer I/O board.
To activate and update your RTC connect the MiSTer to the internet and let it run for around 15 minutes. or from the console:
By default the time zone is UTC(GMT). If you want to get the time of your zone, you need to do following:
- Connect to your MiSTer by FTP/SFTP
- Navigate to /usr/share/zoneinfo/posix folder and find there the name of your place or time zone.
- Copy that file to your computer under the name ‘timezone’
- Copy it back to your MiSTer to folder /media/fat/linux with the name ‘timezone’
From the console you can also force the hardware clock to update and read the time from it.
- store datetime to RTC : hwclock -wu
- read RTC : hwclock -u
