CrossStudio's New Project Wizard simplifies the creation of projects for the STMicroelectronics STA2051 processor by creating a project with the appropriate project settings, memory map files and startup files. See Creating a New Project for more information on creating projects.

##### To create a new ST STA2051 project

- Select the File | New | New Project menu item.
- Select STMicroelectronics from the Project Type list.
- Select the required project template type from the Templates list.
- Set the required project name and location directory.
- Click OK.

CrossStudio for ARM supports the ST STA2051 running applications from both RAM and FLASH.

##### To build and debug an application

- Select the project to work on by using the Project | Set Active Project menu option.
- Select the configuration you require by using the Build | Set Active Build Configuration menu option.
- Build the project by using the Build | Build Project menu option.
- Connect to the appropriate target in the target window.
- Download and start debugging the current project by using Debug | Start Debugging.

The following sections describe the ST STA2051 support in more detail. See ARM Target Support for more information.

### Memory Map Files

Default memory map files have been provided in the $(StudioDir)/targets/ST_STA2051 directory for each processor type. These files are used to describe the memory layout of the target and is used for linking and debugging. The placement of program sections within the memory map for both RAM and FLASH configurations is described by the non-target-specific default memory maps $(StudioDir)/targets/flash_placement.xml and $(StudioDir)/targets/sram_placement.xml.

The memory segment layout for both configurations is the same and is described in the following table:

Type | Description | Start Address | End Address
FLASH | On-chip FLASH bank 1 | 0x400C0000 | 0x400C3FFF
FLASH | On-chip FLASH bank 0 | 0x40000000 | 0x4003FFFF
RAM | On-chip RAM Bank | 0x00000000 | 0x0000FFFF

### Target Startup Code

The default startup code is in $(StudioDir)/targets/ST_STA2051/ST_STA2051_Startup.s. It contains the exception vectors and the default exception handlers. The FLASH version of the code (specified by defining __FLASH_BUILD) is also responsible for configuring memory to match the above memory map and copying the exception vectors into RAM.
