Fast Cyan Flashing

Troubleshooting
1

With certain programs flashed, I’m seeing the Photon go from green, to fast cyan - and continue with a fast cyan… the system seems to self-reset and will sometimes come out with the correct state of pulsing cyan.

Good process:

  1. Slow Green ~ 1 sec (Looking for Internet)
  2. Fast Cyan ~ 1 sec (Connecting to Cloud)
  3. Slow Cyan (Connected)

Current process:

  1. Slow Green ~ 1 sec
  2. Fast Cyan ~ 30 sec (reset (quick flash of red/purpleish), try again)

Question: Can my code possibly cause this type of issue? If so, where should I start looking? This would seem to be part of the bootstrap - something before the code even loads - but not being able to debug the state, I’m not sure where to look to troubleshoot the issue.

Note, sometimes hitting the reset a couple of times will result in the correct processes happening.

Anyone ever see this or know where to start troubleshooting the issue?
