Me too, but that's not what is taking the time.

Sorry if I was not clear enough. I always meant to refer to using kermit binary protocol in combinationwith the loadb command. > I am aware that you have suggested in many places AGAINST the use of > S-record, but there is a genuine use for it. > When using U-boot in a non-Linux bareboard embedded system, you need a > way to give your users the capability > to upload now software.

You could probably wrap the parts in a FIT image, transfer it in binary mode, and use a script to extract the parts and move them into place.
