Responding to: ???'s previous message
That the author(/copyright holder/whomever can do it) of IAP is reluctant to publish details such as resources usage (not to say that it deserves to be published openly), does not mean it is MEANT to be "reset only". It IS supopsed to be a "write to FLASH", if it is supposed to be useful at all.

[...]the only solution known is to puah any variable that must be known after the write onto the stack [...]

What Dufour said above means, among others, that you CAN'T push any variable on the stack without risking its corruption!

Erik Malund said:
There is no guarantee that the next version of the flash write will not use other (I)RAM locations.

... which is a big, big error from the chipmaker's side (here: NXP).

PS. I wonder whether Bill Houghton or somebody other from NXP is still listening here.
