I found lots of infos online, but i am now stuck again.
I am trying to do a JTAG restore using an old style printer's cable (RS232 DB25) on a EOC2611P access point.
The guides seems to refer to a 3.3V pin, which i don't know to which wire i should i connect it to.
Anybody being succesful even by using a different method here??
3,3V = ???
GND = pin 7
TXD = pin 2
RXD = pin 3
CTS = pin 5
RTS = pin 4

Here are a few links:

Right, admittedly we are not in one of the most partecipated forums on the web...
Further research shows that this voltage doesn't have the necessity to come from one of the small numbered wires, in fact some people are just using 2 small 1,5V batteries in series to get those 3V.
Assuming that i put the positive(+) of that 3V on the last pin coming out from the AP and listed as Vcc 3,3V on the picture, where would i connect the negative (-) of that battery's pack? My guess is on the GND but maybe it's wrong????
