Bugfix data synchronization after RTE start:
In previous version invalid data may be transferred in case the communication is corrupted directly after RTE startup. Root cause was that the data was evaluated without caring if a communication error was reported. In the new version the startup condition and evaluation of data is only done if valid data has been received by the RTE => SPI communication is up and runnig.

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

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