i´m new in the forum and have not practice on debricking routers, the only tings i know on this issue its what i found here in dd-wrt.
Following the schematic at
http://infodepot.wikia.com/wiki/Asus_RT-N16 and info at http://www.nslu2-linux.org/wiki/HowTo/AddASerialPort "Using a mobile phone data cable (DB9 serial port types)" section, i have builded a serial cable on nokia DLR-3P, but i couldn´t use it because both HyTerminal and Putty (with the rigth setup on COM1 port), doesn´t recognize the device when hitting Ctrl-C on router power on (try few times) ).
Then i build an unbuffered JTAG adapter (with 100ohm resistors) on a piece of parallel cable(15cm) to fix my bricked rt-n16 (tested and retested few times with ohmmeter), but after howers of trouble with starting giveio.sys on a old ASUS P4 motherboard with native Pport 378 EEC (BIOS), i´m now again faceing problems with C:\TJTAG 3-0-1. In within -probeonly and with few other swiches, by powering on the router each TJTAG session with Ctrl-C in between the first 4 sek., i´v tried to get trough the starting process, but no luck at all!!
The Tjtag starting process always get stocked on "Clearing Watchdog" as you see on my pictures!!!
I would very much appreciate any wise solution or ideeas..
thanks.. also for the very intersting forum You all have builded up.
MOD EDIT - PICTS of jtag adapter deleted. See forum rules on picture size. See also the jtag Wiki article and the /ncw switch
now that i have used this switches, is the Clearing Watchdog bypassed, but as you can see on attached picts, the progress still freez on Probing flash at (flash window:xxx)!!
Have you any other ideeas?? ..need your help very much
in Bios menu "Onboard devices config", the pport its adressed to 378 while the pport mode its in ECP..
i´ll try different settings in BIOS as you say.. i´ll keep you informed..
can yuo please advise me shortly, on how to check that no other programs is using or has loaded my LTP1 parallel port driver??.. What should i look at and where??.. is it in the device manager you are talking about??
i appreciate very much.. .. thk
You should also remove the outer sleeve of your cable and space the wires apart - the jtag interface is intended for ribbon cable where signal wires has a gnd wire between them.
You don't need all ground wires as in a ribbon cable but your wires may pick up noise from each other when they are twisted together like they are now. _________________ Kernel panic: Aiee, killing interrupt handler!
sorry i forget it..
I have installed a vergin XP pro(sp2)from CD in a new partition on my HD, just for this case, without any service Pack update, antivirus, firewall or printer software what so ever
if you tell me what and where i shoul look for to check that no other programs is using or has loaded a parallel port driver, especially HP Printer drivers, i´ll look at it... thk
does that mean that there is no other way to revive the rt-n16,other then with buffered interface??
eventually,can you point a place where i can find schematic for the buffered build??
what about the "serial" procedure?.. is there a hope for this procedure?
thk.. i appreciate very much what you do
