I'm trying to upload an asa and asdm image to an asa and keep getting

%Error reading tftp:// (Unspecified Error)

I can ping my computer (the tftp server) from the ASA and vice versa.

This is what I am doing:

ciscoasa# copy tftp disk0

Address or name of remote host []?

Source filename [asa842-k8.bin]?

Destination filename [disk0]?

Accessing tftp://
WARNING: TFTP download incomplete!

%Error reading tftp:// (Unspecified Error)

I also want these images to be the startup and running images

Does the machine running the TFTP server have more than one Network card (including a wireless one) if so disable the other card temporarily and try again.

I'm also assuming the asa can ping

And I'm assuming is connected to the ASA's inside interface?

Install and Use a TFTP Server
Cisco ASA5500 Update System and ASDM (From CLI)
