I am trying to put a new IOS image on a 2821 box, and TFTP after many many tries with different PCs is not working. I have a USB drive formatted to FAT that has the image on it, and when I do #sh usbflash0 it sees the image and lists the filename correctly. But when I try #copy usbflash0 flash and a few other things, it tells me the source and destination are the same.
I did RTFM as best I could -- I have a library of Cisco books but I did all my Cisco stuff ten years ago when there were no USB ports. One post in this loop says "copy the image from your USB drive..." but doesn't say how. So I think it must be possible.
Thanks in advance for help,
