Stuck on the Rainbow Screen - with IOT only

Sat May 26, 2018 6:24 am

I have a rasp pi 3. I installed IOT, wrote an app and got it running just fine. It's been good for several weeks.

Yesterday, the pi wouldn't boot. Stuck on the Rainbow screen.

There was lightning in the night, so I thought maybe the flickering power supply might have caused this.

I reinstalled IOT, but got the same result.

I installed NOOBS on the SD card, and the pi booted up normally. I put IOT back on the card, and I'm stuck on the rainbow screen again.

So I guess both the pi and the SD card are OK. Something went wrong with IOT (an auto update perhaps?). I'm puzzled a new installation of IOT gets the same result. I used etcher to install IOT. Is there an image file of IOT I could just put onto the the card maybe?

I'd be grateful for any suggestions as to how to get this going again.

Thanks,

John Pedersen

Googling does not find a Operating System called IOT ??

If it's a Raspberry Pi 3B+ and Win10IoT then you have an OS that is not compatible with your hardware. You have to wait until Microsoft release the next version (or see if there's a 3B+ ready beta).

Oops, sorry, I meant Android Things, not IOT.

Android Things is what I flashed onto my SD card, following these instructions: https://developer.android.com/things/ha ... aspberrypi

And that's what won't boot up (though it did before, and I've reinstalled it a couple of times and had it working fine. Not any more...

Sorry for the confusion.

Same answer. They need to update their bootcode & kernel for the new hardware.

You'll have to ask the Android Things developers for that.
