Sharing is caring - A custom Zynthian box

I also have an Iqaudio Dac Pro but am not able to make it work (I only find Iqaudio Dac and Iqaudio Dac+ in the menu to select and both end up with a booting error). Would you be so kind as to help me out to configure the hardware in Zynthian? What am I doing wrong?
Thanks in advance,

Andrew
