my first post here. I have a small problem with transfering IOS image to 2621 router.
When I try to tftp the IOS from rommon i get the following error:
TFTP error 0 received (Undefined error code).
TFTP: Operation terminated.
When I try to send the IOS with XModem i get this error:
ERR:Image size exceeds free flash space
And when i try to dir flash: in rommon i get the following error:
device does not contain a valid magic number
dir: cannot open device "flash:"
I know that the unit itself cannot be faulty, because it worked previously, prior to handing it to me the flash was erased probably.
