ERROR screen and HiFiBerry DAC + RTC [SOLVED]

Hi to you all,

A friend of mine and i build both a Zynthian which was a great challenge.
When i started up my Zynthian, i got a “Zynthian ERROR”-screen while his Zynthian did work.

Only difference was that I had a HiFiBerry DAC+RTC and he had a regular HiFiBerry DAC.
We found the error and I would like to share our solution to you.

I changed two files in the Zynthian map.
Working with WinSCP (or Putty) you could change the parameters of a file.
The information that needs to be changed is as follows:

Insert the following text in /boot/config.txt

dtoverlay=i2c-rtc,ds1307
dtoverlay=hifiberry-dac
dtparam=i2c_arm=on

Insert the following text in /etc/modules

i2c-bcm2835
i2c-dev
rtc-ds1307

That’s all.
After rebooting everythings works well.
