Project may not build with latest IAR EW430 v5.52.1(minor)
The AIR-ZNP projects for the MSP-430G2553 may not build properly in the latest version of IAR -- v5.52.1. This may in fact be an IAR bug. But it is easy to work around.
You will see:
Linking Error[e183]: Static overlay map generation (-xo) is not supported for the MSP430 processor. Error while running Linker
Workaround
In IAR EW430, go to Project -> Options -> Category: Linker -> Tab: List. Uncheck the Static Overlay Map checkbox.
