I am having all kinds of trouble with this beast and am wondering if I fried it.
I actually have 2 of them that are acting the same way.
Is there a simple test to see if the board is still good ?
I have been trying to get some of the examples to work. Blink, and fade.
They dont recognize the USB port.
One of them says that it is not connected when it clearly is.
The other board that I just tested gave me this:
Sketch uses 257672 bytes (24%) of program storage space. Maximum is 1044464 bytes.
Global variables use 26572 bytes (32%) of dynamic memory, leaving 55348 bytes for local variables. Maximum is 81920 bytes.
esptool.py v2.7
Serial port /dev/ttyUSB0

This is when it is trying to upload the compiled sketch and is an indication that it will not work:

Furthermore, I have a brand new board that works just fine.
I sure would like to know what happened so I wont repeat it.
thanks
