OSTC4/5 joined code:
In the previous version code differences between OSTC4/5 were identified using the ENABLE_GPIO_V2 compiler switch. In the new version this is done using the display version as indicator which OSTC model is in used. Since this is detected by Firmware the information is forwarded from there to the RTE. This causes a little delay in the GPIO initialization but this applies only to the cold start of the RTE which should not happen very often.

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.
