I think that there was some bad carachters that i can clean with a pullup resistors on tx, but this isn't the problem in this situation not accept any command.
What can I do?

Thanks

you should try to fix it with resitor (and maybe use a really short cable!), then you should see clearly the uboot messages just after powering on the router. you should be able to send the "tpl" command when you see "Autobooting in 1 second..."

anyway you were using dd-wrt, not openwrt

Hi nebbia88

now I try with a resistors.

Yes this is a bad flash with a dd-wrt image it seems that dd-wrt is not compatible (or the image that i used) with this router.
If i can debrick now i will try the openwrt image.

thanks

Hi nebbia88

I tried using a pullup resistor on tx but the result is the same.
Only way to view correct data is to set serial with 115200 7bit 1stop nn and this is the result:

When I saw "Autobooting in 1 second..." I sent the tpl comman but nothing happened.
What I', doing wrong?

Thanks

You need to get the timing exactly right

retry, retry, retry

OK
but
While type the command tpl , on the console you can see the typed characters?

Now I cleared the text:

no you do not see what you type! it's normal.. but the booting process should stop.

paste "tpl" from clipboard, works better than hand-typing..

Ok I retry

Thanks

nothing to do!!

I tried thousand of times, I tested my adpter rs232-ttl (and work better)
I tried also with openport a sw that have an autosend  function, but uboot don't stop the autobooting.

I checked on serial output this line:
[    0.000000] sys id = 10123 Atheros AR724x rev 1.0 (0x0123)

My wr841n V8.4 has the ar9341 chip (this is the reason that is bricked I thinks) can this cause that the uboot not is responding?

Someone has any Idea??

thanks

no, uboot is OK (you see for example "file: ag934x.c,line", so it's the for your CPU ) and uboot is what should respond to serial.

the fact you probably flashed a firmware for v7.x version (that has ar7241) has nothing to do with uboot!

i found other suggestion for resistors:

http://i1086.photobucket.com/albums/j44 … 91cf54.jpg

what voltage did you get if you measure tx vs gnd on the "ttl side" of your adapter (with router off!)

Are you sure tx is connected properly?

Sounds like you cannot send anything to your router
So double check the cables

I also had the same dubt therefore I tested the adapter connecting the two wires (tx and rx ttl side) together and in this mode i can see the commnad sent.

Then I suppose that the adapter is working well.

Thanks for your reply

What about flow control option ?
