2 development. It might become handy for you to add serial console to your
3 device as well as using JTAG to debug your code.
8 and its pins are routed on the Printed Circuit Board to allow
13 least 4 signals (without modem signaling) to work : VCC, GND, TX and
14 RX. Since your router is very likely to have its I/O pins working at
16 to change the level from 3.3V to your computer level which is usually
22 the top or bottom layer of the PCB, and connected to the TX and RX.
24 Once found, you can easily check where is GND, which is connected to
26 at 3.3V and connected to the supply layer, TX is also at 3.3V level
33 using a speaker or a LED to determine the 3.3V signals. Additionnaly
34 most PCB designer will draw a square pad to indicate ping number 1.
49 to make it perform commands like reads and writes at arbitray locations.
50 Additionnaly it can be useful to recover your devices if you erased the
55 to allow controlling the CPU behavior using JTAG.
61 connected to GND.
