Last night, I loaded the upgraded raspbian, loaded the particle-agent and all worked as it should. Tinker and flash LED etc.
I enabled I2C, and everything came to a stop, if I try to flash firmware to flash LED I get an Error 500.
I setup another SD card, I did get Tinker to work but still can’t get the Flash LED firmware to load (Error 500).
I have tried new SD cards with updated and upgraded Raspbian and particle-agent, with only ssh enabled, but still can’t get anywhere. Guess I will need to wait until @jvanier gets back, unless someone else knows the solution to this problem.
