Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Define state of new GPIO out pins: Some new GPIO pins were initialized but not used. This may cause some random activations e.g. of the red debug LED. To avoid this the output levels are set to inactive levels (e.g. to LED_OFF)

# How to Create From Scratch a Project for _CPU1-Upper_ Code #

The main CPU (aka. _CPU1 Discovery_) firmware is splitted in two parts:
- The proper _CPU1 Discovery_ firmware, with the main code.
- The _protected upper memory_ firmware, which is programmed during _OSTC4_ production, and contains (amongst other things) code used to upload and install firmware upgrades.

## Make a specific project ##

Follow the same procedure than for [CPU1-Discovery](Detailed CPU1-Discovery Project.md), (same processor, same includes) but include the `CPU1-Upper` source directory.
