Optimization Settings

The following option must be specified in the main .gpj project file:

-nostartfiles

This change prevents the use of the Green Hills startup library which this component replaces.

Appendix

The following symbols need to be defined in the linker command file for the project surrounding RAM sections that are to be cleared at init.

SymbolNotes
clearedRamStartTo be placed near the top of RAM, before any *bss or *sbss section have been included by the application or OS.
clearedRamEndTo be placed near the end of RAM but before the definition of any heap memory and after any and all *bss or *sbss sections.

These symbols are used by the library to denote the beginning and end of RAM that will be cleared during application init. The intent is to keep the range as small as possible to optimize startup timing while including all RAM that is guaranteed to be cleared at init. Due to the way Nexteer structures their memory map the cleared section may contain initialized sections (*data and *sdata) as well. This will not cause any functional issues but will hinder performance slightly.

Caution: if a variable is outside of the range between these two symbols its value at init cannot be assured. It is recommended that the .map file be analyzed once the changes have been integrated and the project compiles to ensure that there are no variables that fall outside of this range.
