Hi everyone.
I'm trying to fix a bricked Dlink DSL 502t and load openwrt, and could use some help. Please forgive my lack of knowledge as up until yesterday I'd never done anything in this area.
(As is always does apparently) Upgrading the firmware completely destroyed it, and in my ignorance mtd3 (among others) has been wiped. mtd2 (with adam2) appears to still be intact and functioning.
I've built a jtag cable and I'm trying to connect it to tjag now, but I can't for the life of me get anything to work. The pin layout on the connector is very suspect, as it is labeled
8 9 10 11 12 13 14
1 2 3 4 5 6 7
where as all the diagrams online show for headers in this fashion:
2 4 6 8 10 12
1 3 5 7 9 11
I've been attempting to follow this guide: https://forum.openwrt.org/viewtopic.php?id=7742
but he only very briefly covers the section on how to modify a cable to fit properly (incase you haven't spotted already the header has 14 pins instead of 12)
My cable follows this diagram: http://www.t-hack.com/wiki/images/e/e7/ … altung.gif
If anyone could help me interpret this information, and maybe give me some insight into how the pins need to be connected, or what I am doing wrong, I would greatly appreciate it.
Thanks in advance
ADDED:
I know there is some form of a connection occuring, as hooking the cables up in different ways and probing returns a different CPU chip ID, either all 0s, all 1s or 100000....
