Re: Xmodem on 2950

alk1000 · ‎03-05-2006

Hi All,

The flash –on a CAT 2950- was mistakenly erased using erase flash.

I am trying to upload a new version using xmodem to get 2 sorts of errors as detailed below.

Nothing mentioned on Cisco website regarding this issue.

Any thoughts are appreciated.

Regards,

You missed to initialize the flash. You need to Initialize Flash with init_flash first, then load_helper, then xmodem the file.

Hi,

try this,

Switch# init_flash

Switch# load_helper

then try to use copy xmodem: flash:

Still if u find problem thn,

boot the flash externaly using,

Switch# boot xmodem:

and then copy the ios either thro. xmodem or thro. tftp from the priviledge mode.

I hope this will solve ur problem

Hi Guys,

Thanks for your replies.

I didn't miss initialising the flash as it already initialised (check the output I already attached). Even thought i re-initialised it but to no avail.

joel-metz · ‎03-09-2006

are you doing this through hyperterminal and using the send file feature? If so make sure xmodem is selected in drop down arrow. I ran into this problem with my hyperterminal setup before.

Hi,

As joel said, Pls make sure that you are using send file command with xmodem protocol.

Still if u find problem, pls try to boot the ios externally thro,' Switch: boot xmodem:

and then upload the ios thro. tftp or thro. xmodem.

Problem solved!

You won't guess what was wrong.

The IOS image I was trying to copy was corupted.

I re-downloaded it and it worked from the first time.

Thanks guys for your appreciated contributions.
