I am trying to upgrade the IOS to 12.1(5)T on a 2501.
It had 8MB Flash and I added another 8MB flash. Router recognizes all the
flash chips.
The upgrade fails constantly half-way through the TFTP process. I tried it
via back-to-back serial connection and via ethernet.
I am begining to suspect the new flash 8MB card even though the router
recognizes it as valid.
Anyone had this problem before?
Here is the error message I am getting during the tftp process.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
