I am able to program the ESP using Atmel Studio and the Arduino IDE with no issue after putting the chip into program mode by connecting GPIO0 to ground. The problem is the code never executes. I get the message:
Indicating that the chip has entered the proper boot mode and the code should be running, but the chip freezes, doing nothing. Note: Boot mode 1 is programming mode and boot mode 3 is boot from internal flash. I assumed this was me setting up the SDK wrong or using a version with errors so I flashed the latest AT command firmware to see if the problem was in the hardware. The chip gave the same problem. A normal boot message followed by nothing. Occasional, after resetting the chip, I'd receive a stacktrace like this:
During this time I am also aware that the chip was throwing off a lot of RF interference as every time this stack was printed, every device connected to wifi within a ~10m radius of the chip was disconnected and could not re-discover any network for around 10 seconds. Is it possible this chip is simply defective? Is there an issue with my power supply? I am providing the 3.3v regulator with a 5v 2A USB power brick. All of the capacitors are electrolytic.

Hi Helen,
We do not have any experience with the bare bones ESP chip-sets. OpenEVSE uses the Adafruit Huzzah ESP8266 module which is inexpensive and very stable. We are sorry we could not help answer your question.

I recently purchased a bare-bone ESP8266-12E module(http://www.kynix.com/Detail/1324534/ESP8266-12E.html) but am having major issues with stability. Here is a schematic of what I am using.
