Hi Eric,

why you not use the small model ?
It generates faster and tighter code.
And only such variables, which are large and slow should be placed in the xdata space.

Nevertheless I see no reason to switch the EXTRAM inside the main(). Only, if xdata variables preintialized it can fail.

Also, if not the full 64kB xdata was needed, you can set the xdata start always above the internal xdata space (tell it to the linker).

Also you can copy the startup.a51 into your current project and modify it.
