Hi Ray,

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
snd-bcm2835
i2c-bcm2708
i2c-dev
rtc-1307

– 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.
