I have just started exploring Brillo+Edison.
I have tried helloLED example and flashed Edison with helloLED.
After flashing board keeps on rebooting. Following is the debug.
Any idea on this error?

I recommend you to take a look at the following thread: . Another user posted a quick guide about flashing Brillo. He mentioned that he faced an issue with the Wi-Fi/Bluetooth drivers, but he was able to solve it. You might be getting a similar issue.
If the board reboots itself during power cycling, then the issue might be with the power supply. Make sure the power supply works fine. If you are powering the board through the USB port, consider checking the cables or changing the USB port.
On the other hand, I recommend you to contact https://developers.google.com/brillo/ Brillo | Google Developers. They are the experts with Brillo. Hopefully they will provide you a better assistance.
I found that after successful build, as per instructions, if I give
fastboot devices -> provision -> fastboot reboot
After fastboot reboot the board keeps on rebooting as I mentioned earlier.
But if I power cycle the board i.e. connecting the USB cable again to power ON the board then problem disappears.
Any thought on this? Am I missing something?
I have given supply from the USB port on the back side of the CPU. Earlier I was using front USB port to provide supply to Edison.
I think front USB ports won't be providing sufficient current.
I haven't faced problem again. I'll update here my further observations but right now this is the status.
