Failed to boot BBAI64 suddenly

General Discussion

Hi experts,

I was using BBAI64 just fine until a little while ago, but it suddenly wouldn’t boot.

So I took the following actions, but this message was displayed.

  1. remove all power
  2. insert sd card and hold down the boot button and keep it pressed
  3. insert power
  4. wait for lights to start flashing and then safe to let go of the boot button

How can I fix this?

It depends, if you have nothing of value in emmc then reflash (all will be lost) with the IoT flasher image. It comes down to this, waste time debugging or just start over. It just depends on the value locked inside the SoC.
