I received my board yesterday and I am unable to boot it from the official Debian image (totally no HDMI output), and then I tried to use the sd image from the GitHub release v2.11.5, but it still failed. The screen showed it got stuck at mipi_0p9: disabling, and pressing the keyboard won’t help. What should I do now?
Is the sdcard.img file on GitHub release also a Debian image? I tried the Debian image and it did not work and I contacted the seller, he informed me that I need to upgrade the uboot using the image from GitHub, and gave me the link to the Github release.
