To create a new Logic Product Development SDKLH79520-10  project

CrossStudio for ARM supports the Logic Product Development SDKLH79520-10 running applications from both RAM and FLASH.

Warning: Downloading to FLASH will erase the and re-program the FLASH memory thus removing the boot loader firmware shipped with the board.

The following sections describe the Logic Product Development SDKLH79520-10 support in more detail.

Memory Map Files

The default memory map file $(StudioDir)/targets/LPD_SDKLH79520_10/SDKLH79520_10_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
RAM External SDRAM 0x20000000 0x21FFFFFF
FLASH External FLASH 0x40000000 0x40FFFFFF
RAM Internal SRAM 0x60000000 0x60007FFF

Target Startup Code

The default startup code is in $(StudioDir)/targets/LPD_SDKLH79520_10/SDKLH79520_10_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.
