Bugfix initialisation of surface pressure: A reset of the RTE less than one minute before a dive starts may cause problems in the depth calculation because the default pressure is not set yet. To avoid this the first measured pressure value will now be used as stable surface pressure to close the gap till the stable surface pressure is evaluated.

# 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.
