Hi
My router got bricked and yet when I have a new one, I decided that I can fix my DIR-300 with a JTAG cable.
Since I have really small knowledge in electronics, I need a little bit of help.
I found out that my JTAG on DIR-300 looks like this:
and this is the scheme
I know that this scheme will work bad with my JTAG input and it may destroy my router.
There are changes that must be done in the scheme with the order of the cables.
Can anyone make me the right scheme with right numbers ? Please I would really appreciate.
When I get that info, my friend will make the cable for me and I'll post effects of debricking my DIR-300.
XXX(pin hole in my router according to the picture above) - XX parralel's
TDO(5th pin) - 13th parralel's
TDI(3rd pin) - 2nd parralel's
TMS(7th pin) - 4th parralel's
TCK(9th pin) - 3rd parralel's
GND(6th pin) - 20th (or 25th... or both at once ?) parralel's ?
I need just 1 GND connected right ?
Correct me if I'm wrong.
EDIT:
I need just these 5 pins ?
Sorry for my lack of knowledge, please understand...
