cisco 3620 & xmodem'ing flash from rommon


Hello all,

I erased my flash recently and decided to reload through the rommon. I used the command

xmodem -c c3620-ios-etc-etc.bin

to prepare the router to accept a file, and sent it via xmodem on hyperterminal.

After about an hour when it finishes... it automatically starts trying to erase the flash? and I see a list of sectors coming up until it stops with the message:

"flash sector will NOT erase...aborting"

What does that mean!? Is the flash corrupt or damaged ?

It's done this twice in a row?

I've also tried using another option with the xmodem command, the -r option copy's the image to DRAM for launch...

and that worked fine... apart from the fact that when I reboot again, as it was running from DRAM, it's all lost.

help me please.. google throws up nothing with regard to that error message.

can you try and manually erase the flash with the ´erase flash´ command and then try the procedure again ?



thanks for your response.

I have just erased the flash, and it showed a whole series of e's across the screen IIRC as it cleared the flash, but again, i'm getting the same error at the rommon prompt when I xmodem the file down to the router and it tries to clear the flash again before installing....
