I built my system with a Pi4, recalbox works fine out of box. Having a little 1.8' TFT SPI screen I managed to install it on the GPIO and it works nice.
Since my goal is not to use it as main screen but only as a secondary one I followed this tutorial Second miniTFT screen for scraps and videos for giving it the utility described in the page "Second MiniTFT etc etc."
The problem is that whenever i boot the system, also after i setted all the value as described, my system recognize the little TFT screen as main screen.
Could you help me solving this problem? Thank you.
