CrossStudio's New Project Wizard simplifies the creation of projects for the ARM Evaluator7T 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 ARM Evaluator7T running applications from both RAM and FLASH.
Warning: Downloading to FLASH on the Evaluator7T will erase part of the Evaluator7T firmware. See Restoring Evaluator7T Firmware for details of how CrossStudio can be used to restore the Evaluator7T's firmware.
The following sections describe the ARM Evaluator7T support in more detail. See ARM Target Support for more information.
The default memory map file $(StudioDir)/targets/ARM_Evaluator7T/ARM_Evaluator7T_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 | 16 bit FLASH bank using ROMCON0 | 0x01800000 | 0x0187FFFF |
RAM | 32 bit SRAM bank using ROMCON2 | 0x00040000 | 0x0007FFFF |
RAM | 32 bit SRAM bank using ROMCON1 | 0x00000000 | 0x0003FFFF |
The default startup code is in $(StudioDir)/targets/ARM_Evaluator7T/ARM_Evaluator7T_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.
Downloading applications into FLASH will cause part of the Evaluator7T to be erased and therefore destroy it. This is reversible as CrossStudio can be used to re-program the firmware image into FLASH.
