3660 ROMMON Error

[kcgeorge1218]

Hello -

Trying to upload a code to a 3660 router via xmodem and after copy the code to the flash, it comes back with an error -

"Erasing flash at 0x30000000sector erase failed at location 0x30000000, status 0x

20202020.

flash sector will NOT erase...aborting"

I have tried it a couple of times and I am out of options. Please advise.

Thank you.

Hi GK,

I believe this is hitting a BUG but before I confirm , do you by any chance have the output of "sh flash all"?

I would also suggest checking and make sure that the flash is well seated and then try the load again.

Hi Rick -

I gave that a shot too...am trying it again.

Hi Ankur -

Unfortunately I did not. Any work around this or shd I try a different code ?

Initially, I was trying to TFTP a 12.4T code to the 3660, when that didn't work, I tried the xmodem procedure and that's when I get to see the error.

Thx

Hi GK,

If this is the bug which I presume is , give a try with this workaround

Workaround:

-----------------

1. Boot from IOS image on PCMCIA card

2. Erase flash SIMM

3. Copy IOS image from PCMCIA card to flash SIMM

OR

1. Invoke xmodem with '-r' option so that IOS code is xmodemed into

RAM and executed.

Hi Ankur -

I tried the xmodem with the -c option. Would that have made a difference ?

My other option is I have to find another 3660 and try to copy the flash image onto the flash card and try to boot..

[kcgeorge1218]

Giving the -r option a try now.

Hi George,

Can you give xmodem -r a try?

Is there a bug alert for the 12.4(13b) code ??

[ankbhasi]

Hi George,

I don't think so. The problem is with Boot ROM version 12.0(6r)T.

Did xmodem -r option worked for you?

Have the xmodem with -r running....shd take another 10 mins.

[kcgeorge1218]

The xmodem -r worked.

Hi George,

Happy to know it worked for you.

Now you can erase flash as your router is up with the IOS after the xmodem and then after erase do a copy tftp flash so that image will be loaded on flash as right now it is in DRAM.

Thx Ankur for the help. Much appreciated.

I had to revert back to the old code, 12.1(5)T12. The 12.4(13b) gives an error when I try to TFTP it. TFTP protocol error - too large to handle.
