@Nick A@Sadiq AhmedHey Nick,I've tried to boot BigTreetech CB1[Provided by Sadiq] and a few more.But when i put Image burned sd card in TF slot and turn on the box but my screen didn’t get any hdmi output[for 3-4 minutes] then i removed the sd card from TF slot.I Don't have that much knowledge about SoC,Bootloader blah blah blah.Can you find any mistake or suggest me a compatible os?
