You don't provide much information (like which software you use to do
the copying - U-Boot, Linux, ... ?), but let me guess...

Let me guess: you do this in U-Boot, and forget

* that U-Boot commands take are usually interpreted in hex, i. e.  if
  you  enter  a byte count of '3285336' than this is 52974390 decimal
  or 50+ MB which definitely *is* outside the available flash


* that the U-Boot "cp" command operates on 32 bit words (= 4  bytes),
  so when you want to specify a byte count you have to use the "cp.b"
  variant of this command
