I finally get into the console
what command should be used to reload the firmware from the debug console??
Categories: WGR614L Open Source Router
Has anyone used the debug console on a WGR614 yet.
I have failed in all of my attemps to talk to it.
My hardware is the recomended rs232-3v3 usb adapter cable.
The cable works with othe test equipment.
Thanks

By the way I have noticed in your earlier email about this BPS 38.4 Kbps. Which doc are you using. The one that you should use is this one and it does have the correct baud rate. We would need to get the documentation corrected and we appreciate your effort on this a lot. I will respond to other threads separately.

Nachi,
On one of my routers that won't boot I see an ifniite loop in the serial console. It just starts over and over again.
So I never get to the CFE prompt. Any ideas on this?

It is evident from the dump that every time your kernel is trying to boot. Actually you need to press ctrl+c while rebooting the router to get the CFE prompt. Please try that.. if you have already done so please make sure that your minicom is properly configured.

We've just published an article by BrandonC showing how to recover the WGR614L router using a serial console and cable. I thought this may be of interest to those participating in this thread!
You can find the article here:

I finally got access to the wgr614.
The doc is wrong speed must be set to 115kb not 38.4.
Now that I can talk to it, how do I get control of the wgr614 to try and reload the firmware???
looking at the output from the monitor it appear that there is no way to use it.
attach boot up output from wgr614::
