I am struggling with installing OSPI from scratch. Unfortunately it is not so simple. I got stuck with configuring the RTC.
– Following devices are added to /etc/modules
– dtparam=i2c_arm=on is enabled in /boot/config.txt
However the hwclock is not accessible. I got this:
[email protected]:~ $ sudo hwclock --debug hwclock from util-linux 2.25.2 hwclock: cannot open /dev/rtc: No such file or directory No usable clock interface found. hwclock: Cannot access the Hardware Clock via any known method.
It works fine on the old image with the same settings. I assume that something more is missing from the configuration.
