CrossStudio's New Project Wizard simplifies the creation of projects for the Analog ADuC7020 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 Analog ADuC7020 running applications from both RAM and FLASH.
The following sections describe the Analog ADuC7020 support in more detail. See ARM Target Support for more information.
The default memory map file $(StudioDir)/targets/Analog_ADuC7020/Analog_ADuC7020_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 |
SRAM | Internal SRAM | 0x00010000 | 0x00011FFF |
FLASH | Internal FLASH | 0x00080000 | 0x0008FFFF |
The internal SRAM is also mapped to address 0x00000000 in both RAM and FLASH configurations in order to allow the exception vectors to be modified at runtime.
The default startup code is in $(StudioDir)/targets/Analog_ADuC7020/Analog_ADuC7020_Startup.s. It contains the exception vectors, target specific startup code and the default exception handlers.
