Why would you want to do that? It is usually much easier to debug the
original code following the designed-in steps of  the  initialization

It is actually not difficult to make the code to  be  startable  from
RAM,  but it requies some modifications, and you have to know exactly
what you are doing.

The fact that you have to ask if this is possible suggests  that  you
should  better try to get the original code running (from flash). [No
offence meant, just speaking from experience.]

You could end up being oddly sad and full of a strange, diffuse  com-
passion  which would lead you to believe that it might be a good idea
to wipe out the whole human race and start again with amoebas.
