ESP12F doesnt work after I recycle the power.

Hi,
I have setup auto programming of ESP12F module with CH340G. The program runs well once i upload program via arduino. As long as board is powered up it runs. But once i recycle the program doesnt run!!

How to solve this issue?

However I have noticed that once i connect the reset to ground, the program runs normally. Everytime there is a recycle in power i do not prefer to do hard reset.

I'm sure this is not the entire schematics. :?
What did you do to GPIO2 and GPIO15?
Why did you connect the DTR line to the enable (EN)-pin of the ESP, this should be the reset-pin if you actually want the ESP to reset. :idea:
