Hello there,
I am beyond my expertise (that which is already limited) have found a guide. Now the guide uses ili9486 so it was substitute it will ili9341 as well as the build they used official build am using Armbian_22.11.1_Orangepi3-lts_bullseye_current_5.15.80 and int with a new one found in the fbtft library. I also need to translate for Russian with chrome not their are photos of it working but all I get is a white screen. here is my version of the overlay.

};
now i did a dmesg | grep spi and the touch is loading but not the tft just not sure how to fix it I also read though a lot of forums for some sort of template for this device but still stumped.
