I've been using an Edison breakout board for many projects over the past few months and had zero problems with it.
On Friday, I was putting the Edison into my Roomba so I could start scooting around. When I plugged the Edison in, I noticed that DS3 stayed on longer than usual. Then I saw that DS1 and DS2 were blinking quickly in unison. I left it unplugged over the weekend to see if it would sort itself out. Came back today, same thing is happening. The serial port seems to connect, but I see no output in PuTTY. I'm unable to reflash the board, as the EMMC doesn't show up when plugged into my computer. I've reseated the SoC and used different power sources (2 different USB cables and 2 different power supplies). Same thing happens every time.
I have not tampered with the hardware of the breakout board. I typically use USB devices and python scripts for my projects.
Any idea what could be causing this behavior? Is it more likely the SoC or the board?
Well, I think I figured it out.
After having it plugged in for a while, I noticed a strange smell.
And a bright orange spot on U39.
So I'm going to get a new kit and see if that fixes it. If not, I'll be back!
