asteele 0 Posted March 29, 2023 Hello, I'm trying to get Android running on my board. I flashed Android 12 using Balena Etcher to the microSD card, then inserted the card and plugged the board in. Nothing happened other than the red power light appearing. I have a monitor plugged in via HDMI, and a wireless keyboard + mouse. Power is from the DC input jack. I also tried removing the microSD card & powering on, but that also didn't do anything. When the microSD card is removed and I plug the USB-C into my computer, I see this the D & E drives: but when the card is inserted, nothing changes on my computer. I inserted the microSD card into my computer directly, and this is what that looks like: I don't know where to go from here, as nothing I do seems to have any effect.

tooz 52 Posted March 30, 2023 hello @asteele, it's likely that you're using an inadequate power supply that's not providng enough power to the board. the partitions seem correct though Share this post Link to post Share on other sites
tooz 52 Posted March 31, 2023 another thing to check is whether the jumper's attached or not -- if it's attached the board stays in maskrom mode Share this post Link to post Share on other sites
asteele 0 Posted March 31, 2023 Thanks for the reply! I will try on a beefier power supply and report back. Share this post Link to post Share on other sites

tooz 52 Posted April 6, 2023 hello @asteele, does the issue persist if you're using other monitors? with the information provided, the other solution i can think of for now is to re-burn the sd card (or get another sd card to burn even) does the board work ok with emmc?

Both externally powered. Both via HDMI, though. Quote with the information provided, the other solution i can think of for now is to re-burn the sd card (or get another sd card to burn even) does the board work ok with emmc? No, when I remove the SD card I also get no display or any kind of information out of the eemc. I can get another SD card and see if that makes a difference.

asteele 0 Posted April 12, 2023 @tooz I tried with a new SD card but that did not change anything. I did figure out the problem, though. I was flashing the image "Tinker_Board-Android12-v0.0.3-20221002.img". When I tried using "Tinker_Board_2-Android11-v2.0.8-20220503.img", it booted correctly and worked as expected. Thanks for your help troubleshooting. Share this post Link to post Share on other sites
