Porting newlib is not difficult, but advice for the beginner is thin on the ground. This application note is intended for software engineers porting newlib for the first time.

The detail of all the steps needed are covered here, and have been tested using newlib versions 1.17.0 and 1.18.0 with the OpenRISC 1000 .

For those who already have some experience, the entire porting process is summarized in the final chapter, with links back to the main document (see Chapter 9). It's a useful checklist when carrying out a new port.
