Check if the image is loaded into Flash correctly. Maybe it is corrupted. Try reloading it over XMODEM.


Also, do you have enough RAM for the image?

Can you post all of the output after router boots? Including image decompression etc.

Do you have another 1841 available? (I would hope so and that it was the source of the alternate flash that you attempted to use) If so I would suggest taking the flash from the router having the problem and insert it into the other 1841 and see if it boots there. This will evaluate whether there might be some physical problem with the flash and whether there is some problem with the image on the flash.


Also it would be helpful to know if this router has booted and run successfully before and this is a new symptom or whether this is a new router and exhibits the problem the first time you try to use it.


I also note that the version of code on the flash appears to be fairly old. It might be good to try a newer image on the 1841 and see if that makes a difference.
