lloydhussell 0 Posted October 20, 2023 Hello. I booted the Tinkerboard2S and plugged it all in like my old dev board. Nothing came up on the screen. I wanted to flash, and then for some reason there was a jumper left across the power on and maskrom pins. I took it off and then I was able to flash Android12. Plugged everything back in but no signal. How can I fix this, as the guides are very limited. Thanks. Share this post Link to post Share on other sites
tooz 53 Posted October 23, 2023 hello @lloydhussell, if the maskrom pin is inserted, the tinker board 2s enters rom istead of system, and having no hdmi output is expected. Share this post Link to post Share on other sites
lloydhussell 0 Posted October 23, 2023 Yes, sorry. I made this and then figured it out right after but couldn't delete the post because it hadn't been approved by a mod yet. However, I couldn't actually see any instruction for this in the tinkerboard guides. Could you point me to where it is, so I can use it as a reference for others in the future as well. Or if its not there, can it be added please. Share this post Link to post Share on other sites
