Very nice share. Thanks!
My Only doubt is when using a usbttl. Have you had any luck?
In the diagram it says +3.3v to pin 2. (No problem there)
But then it says - 3.3v to pin 10. (not too clear)

Is - 3.3v the same thing as ground?
Also the diagram says that usbjtagnt pin 2 must Also be connected to flash pin 10???

So bottom line, how am I suppose to connect usbttl - 3.3v and jtag pin 2 to flash pin 10?

Any clarification would be Greatly appreciated!!!!!

Thanks guys!!
