** [tickets:#156] atsam4sa16c - wrong flash definition**
**Status:** new
**Milestone:** 0.9.0
**Created:** Mon Jun 26, 2017 11:18 AM UTC by Robert Schwarzelt

Hi,
Flash Definition of `atsam4sa16c` in `src/flash/nor/at91sam4.c` seems to be
wrong.
`atsam4sa16c` does not have 2 Flash Banks with 512kB each. It's just a single
one with 1024kB.
Fix found below worked fine for me (on `atsam4sa16c-au`).
Regards Robert
