Problems in running IOS image from tftp

roberto.sassi — Mon, 11 Mar 2019 20:11:22 GMT

Hi everybody,

I have a Cisco 5505 that had its disk erased (erase:disk0) and now I am trying to load a new image (822 or 813) from a tftp server.

From the ROMMON prompt I have configured the relevant parameters and run a tftp command.

The tftp transfer seems to complete successfully but then it gets stuck on "...loading".

I have tried different versions of IOS and I always experience the same problem, even though, with older versions of IOS (7.x), the device manages to reboot itself but then it crashes with the following error:

"Error : Uncompression of the image failed.

invalid compressed data--format violated"

Could it be an hardware related-issue or a licensing problem maybe? or am I missing anything obvious?

also, I need some help in regards to the license: once restored, how do I get my 50 users license back?

Any help would be appreciated,

thanks in advance,

Rob

Can you copy the exact procedure you are using? And the exact name of the file you are trying to load? Also which Tftp server you are using?

Hi Paul,

thanks for your reply. this is the procedure I am following:

1 - Assigned 1.1.1.2 address to my laptop and connected the laptop to the ASA via console cable

2 - On the ASA, at the ROMMON prompt I enter the following commands:

ADDRESS=1.1.1.1

SERVER=1.1.1.2

PORT=Ethernet0/0

IMAGE=asa822-k8.bin (I have also tried the following IOS versions: 831, 802, 723)

tftp

This is the outout after running the tftp command:

ROMMON Variable Settings:
ADDRESS=1.1.1.1
SERVER=1.1.1.2
GATEWAY=0.0.0.0
PORT=Ethernet0/0
VLAN=untagged
IMAGE=asa822-k8.bin
CONFIG=
LINKTIMEOUT=20
PKTTIMEOUT=4
RETRY=20

tftp asa822-k8.bin@1.1.1.2

very strange, it looks like the image gets installed. Is it possible for you to try with another TFTP server? I use TFTPD32.

...worked at the first try, Paul!

Changing TFTP server did not even crossed my mind...I've been using Solarwinds for years and never had a problem...

thank you very much for your advice..
