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.
CrossStudio for ARM supports the ST STA2051 running applications from both RAM and FLASH.
The following sections describe the ST STA2051 support in more detail. See ARM Target Support for more information.
The default memory map file $(StudioDir)/targets/ST_STA2051/ST_STA2051_MemoryMap.xml has been provided. This file is 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 definitions have been provided for both RAM and FLASH configurations. The default target definitions are ST STA2051 - RAM and ST STA2051 - FLASH.
The RAM target definition configures memory to match the above memory map.
The FLASH target definition maps FLASH at address 0.
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 BUILD_FLASH) is also responsible for configuring memory to match the above memory map and copying the exception vectors into RAM.
