问题
I'm new to Android Things, so would beg your pardon for any silly mistake. I'm using Raspberi Pi 3 Model B, and installed Android Things 0.5.1-devpreview on the sd card. But it's not booting. The board is fine as it's working fine with NOOBS and LIBREElec. When I start the board with Android Things it just shows the rainbow image of raspberi two times before shutting down. Please help. I've downloaded the zip from https://partner.android.com/things/console/#/622pn5/build and unzipped it (using fedora, so unzipped using Archive Manager), and Flashed the image to SD Card using Etcher. I'm just unable to boot Android Things in Raspberi Pi, this problem doesn't includes any coding (but a development related problem), so I've not pasted any code here. Again beg your pardon for any stupidity as I'm new to Android Things.
回答1:
Try a different power source. I noticed when I used one that's too low for the board the board wouldnt boot up.
回答2:
try using dd to put the image in sd.
It worked for me.
