O2+ failure - what does blink pattern indicate?
-
The topic was not helpful.
I've fried all of my expansion docks. When replacements arrive I'll use one and uart receive to listen to tx0 on the broken device to see how far it boots.
If that experiment yields sensible results I'll post to help out the next person with this issue.

Hi, i have similar problem
But my booting is runs about 23-24 seconds before stops
I can get boot log from UART, powerup without UART connect, and after yellow led turns on - connect UART, so few first lines were corrupted.
this is bootlog
https://gist.github.com/YADeM/6537ccd51b827da95512aa44b5e2842c
Also i try to check power - all is ok - i powered by AMS1117-3.3 with 200uF capacitor
Maybe someone have problem resolve?
-
@Pavel-Helmer Ironically I'm setting up right now to monitor the boot process. I'll post my results as well. Will look at your results in a bit.
thanks!
Bill

@Pavel-Helmer Here's an example of a boot that completes. You'll find the EEPROM read at 16.89 seconds.

That was easy - kernel panic. Will try to re-flash.

...and more...Anyone pick up any bits of wisdom from the two lines prior to the kernel panic?
--Bill

The spidev thing is not a kernel panic but an entirely routine kernel warning that is the loud evidence of an argument between upstream developers, but looks like that was not your question was about.
Was this a warm reboot without a power cycle?
-
@Chris-Stratton This was a cold boot.
Apparently the device was in the process of failing and has now failed hard. There is no output at all on power up. The device won't factory reset via the breadboard dock reset button.
On to the next problem....
thanks!

@Chris-Stratton I take that back! Or at least some of it. Was sitting here wondering which of the 30 problems I'm going to tackle next. I wondered, since that failed device has cooled.....
I grabbed the device out of it's new home, one of the fried expansion docks, and put it back in the breadboard dock. Applied power, and voila! The LED came up and went into the same failure pattern as before. Is there a possible heat issue?
Immediately I tried to replicate this magical feat. Now the device is back to providing no external clues - looks dead.
