How big is your CF again? How big is the IOS you are trying to load? Upload the IOS that require only 64mb. Try using TFTPDNLD process as this is alot faster.

Ok then. Reload the router and let it go into ROMmon. On the first prompt type "i" and hit return. Load the IOS again using TFTPDNLD. Make sure you load the IOS that requires only 64mb and not the larger one.

Ok. Now I'm getting confused. Your post shows that the router is unable to boot but you are more concerned about the CF upgrade from 64mb to 128mb. Am I understanding your issue?
If this is your issue, my question is this: Is the 128mb CF formated by the router?

Hi,
Actually i have no much more idea but i know this router is support 128
MB flash and my DRAM is 512.

What is the result of the command "dir flash:"?
04-10-2010 02:55 AM
hi,
Readonly ROMMON initialized
rommon 1 > dir flash:

Right, this can mean either the following:
1. There is no CF in the CF slot of your router; or
2. CF is faulty
Have you tried loading the IOS into the DRAM using the "-r" option?

hi,

when try to upgrade 128MB flash.

Hi Arup,
Kindly leave the 128mb CF out of the picture as of the moment. The current issue is that your router WILL NOT BOOT. I would like to solve this issue first before tackling the 128mb issue.
If you say that the 64mb CF works in other routers, kindly insert the 64mb CF into the router and see if it will boot.
