@Nick A I have one of those T95 H616 AXP313a tv boxes. I have successfully compiled a mainline U-Boot image and it boots fine, all with UART input/output, but none of the images from your github repo work.
I only managed to boot MiniArch images up to 6.19 kernel but I couldn't get HDMI, Ethernet, WiFi or Bluetooth to work at all. Got any idea what could be missing? I can help in debugging if you'd like.
I attached the extracted and decompiled DTS from the stock Android 10 firmware of the device.
Thank you
