....and one more question after further study....

5/ I notice you copy from the flash into the temporary buffer if we're 
not 512byte aligned, or for the final fragment of size < 512.
You also say:
  *  NOTE: When programming data into a sector that is already partially
  *  programmed, all new data MUST be programmed into previously
  *  unprogrammed 16-byte (128-bit) [Ed: Assume 512-byte now] blocks.
The statement implies you cannot write a block unless the flash has been 
previously erased => all 0's or FF's. So why bother copying these (dst) 
back into the temporary buffer prior to copying the partial (src) over 
the top ?
May as well dispense with the temporary buffer and just back the (src) 
pointer back into whatever crap is in RAM there and write that into the 
512-aligned-dst (similar with the far end).

Seems to me the only way to achieve what I think you're trying to do is 
to make a whole segment copy prior to erase, and then write overwrite 
that huge (8k or more) buffer with (src), then program that. Have I got 
misunderstood something here ?
