[En-Nut-Discussion] Write to flash in Ethernut 3

[scostas]

Hi all:

I've been working with Ethernut 2 for a time, and now I want to upgrade
some systems to Ethernut 3. But in the old systems I use the external
521Kbytes Flash to store data. How can I write data to the 4Mbyte Flash
chip availabe in ethernut 3? I now that it can contain the code being
executed, so how can I now the current size to be sure I don't overwrite
it with my data?

Thanks in advance.
