it'll take a day or two till I can get to it but I'll prep my RT for jtag (clean holes & install header) and see if I can help.
I really would be a big help if you could remember what bricked the router in the 1st place.. A bad flash or config is one thing.. The router coming up bricked one morning after happily running or a lightning storm is another.
Good night.. Get some rest.. You will need it _________________ [Moderator Deleted]
well.. i´ll try to write down as much as i remember
If the following detail could help, i can tell you that once with homemade cable i got the right "EJTAG Version" on "TJTAG3.0.1" prompt, but that happed only 1 time in all my testing, with still no respons on IPMCode
Concerning the way i bricked the asus device, if i remember correct, i think that i was playing stupid with "router table" setup, thats because i had another old router (trust speedshare-turbo 108MB)connected to the rt-n16 trough LAN-ports
At moment of bricking, the software in the rt-n16 was the original.. i think it was "Asus 1.0.9" or something like it
The router now gives no sign of life..
Only WAN and LAN 1 to 4 led are lighted for a short moment on power cycling. After the brief moment every led goes off, unless an activ ethernet cable is plugged in to rt-n16 LAN-port

3.0.1 will NOT work !!! Something is wrong here, just can't figure it out, you get the processor ID... one thing is curious, and thats the parallel port stats, I usuall get something like this:
Intial value of Control register is 0000000C
Intial value of status register is 000000FF
11111111 (000000FF)
Status bit 7 Busy Inverted pin 11 = 0
Status bit 6 *Ack pin 10 = 1
Status bit 5 Paper-out pin 12 = 1
Status bit 4 Select pin 13 = 1
Status bit 3 *Error pin 15 = 1
* means low = true, e.g., *Error
see the Intial value of Control register is 0000000C _________________ Want JTAG support - Donate a router

Hi again Tornado,
as far i can see, there is also a difference between yours and mine on "Status bit 7 busy inverted pin 11", where yours it´s on 1 while mine it´s on 0
Please, tell me if there´s something i can do to help..
i´ll appreciate it.. I will keep on trying
Hi,
If you think that it could help, i can try jtagging on another motherboard (asus P5Q-E, core2cpu-3,2GHz).. in this case the p-port will not be a native one, but on a PCI-slot, with an "I/O" other than 0x378
Please, will you tell me wich flash chip /fc:xx i have to pick up for rt-n16, so i can try to insert it manually..
Maybe if you feel like, you can tell me shortly how or where to find info for using /start:xxx and /length:xxx
What do you think is the best TJTAG version i should use for testing??

works for me... It took a while to prep the router cuz my jtag holes were filled with factory solder. I had to clean that out and install a header before I could test.
I used both 3.0.2 RC2-1 & the new one Tornado sent me to test 3.0.2 RC2-3. Neither had a problem recognizing the processor, flash, impcode and set the instruction length properly.
You have a problem with your rig, your setup, or your router is broke (that is why I asked what caused it to need jtag)

You have a problem with your rig, your setup, or your router is broke (that is why I asked what caused it to need jtag)
What is the rig:?: is this the PC??
..eventully, how can i check for problems on the rig and/or in the setup?? ..where should i look for??
Have you noted the difference between your prompt and mine concerning "bit-7 busy inverted pin-11", yours it´s =0 while mine it´s =1, does it mean something?? ...whats the differnce between MIPS and LV mode??
If you think that it could help, i can try jtagging on another motherboard (asus P5Q-E, core2cpu-3,2GHz)

Dear Tornado and barryware,
i appreciate very much your effort.. very kind of you both,
but really don´t think that i´ll spend anymore time on this, expecially if there is a big possibility that it´s an hardware brick..
Please.. would you like to point me a good router to buy, maybe a new stable wireless model(300Mbps or dual-band), possibly with a well-defined JTAG and Serial recovery procedure..

If you can send the bricked router to Barry or me, maybe we can de-brick it ? _________________ Want JTAG support - Donate a router
