[Solved] My spark goes to flashing green forever

Troubleshooting

Hi @rei_vilo Thanks for the reply. After I had made the above post, I went back and flashed the cc3000 and the tinker on the second core that I was also having the problem on. That went very well and the unit is now working fine.

Not sure which core I had a problem with late yesterday but I had attached a jumper in the wrong place drawing a lot of current through the regulator. This is maybe a real stretch but I am wondering if a core that might be damaged in this way could cause my AP to get in a latched up state causing difficulties with a second core.

There is a lot of IFs here but am just trying to put all the facts together for a clear picture of the situation.

I’m glad one of your cores works fine, and sorry for the other one.

I had the same problem with a short on another board —not Spark Core. So I guessed the regulator was killed. But investigating and replacing it would have taken too much time, so I bought another board.

Now, the CC3000 is rather like random: sometimes it works, sometimes it doesn’t. Texas Instruments has now much more stable WiFi radios with the CC3100 and the CC3200. The later combines the WiFi radio with an ARM Cortex M4 on a single chip. Really nice and very reliable.
