7.2Tool options for own projects

Valid load module files for MB91360 devices can only be achieved if the language tool configuration is appropriate. If you use the provided samples or templates, you do not have to worry about these settings.

The most convenient way to create own projects is to copy the provided Template-Project from the sample-directory and use it as “blank sheet”. However, if you intend to create projects “from scratch” without the template, the following settings are important.

Target MCU (“Project – Setup” menu) : make sure “MB91FV360” or “MB91F362” is selected as the target MCU device.

Linker Settings (“Project – Setup tool options – Linker – Disposition”) : MB91360 devices use a fixed memory map for code stored in Flash-ROM or data assigned to the internal RAM. In addition, certain Flash-sectors have special meanings, such as the boot-sector (application always starts from 0F4000) or the kernel of the debugger stored from 0F0000. Therefore, make sure the following memory map is applied:

Memory Type	Used for		Area	Sections
Data RAM	Stack		3D000..3DFFF	STACK
Data RAM	Variables		3E000..3FFFF	DATA, INIT
Flash ROM	User Code		080000..0EFFFF	CODE
FlashROM	Kernel		0F0000..0F3FFF	1.1.1.1.1	Reserved !
FlashROM	Boot-Sector,		0F4000..0FFFFF	START,	CONST,
	constants	and		@INIT, VECTORS
	vectors

Table 4: Memory Map

Your linker settings should look like this:

-ro CODE_AREA=0x00080000/0x000EFFFF -ro ROM_AREA=0x000F4000/0x000FFFFF -ra STACK_AREA=0x0003D000/0x0003DFFF -ra RAM_AREA=0x0003E000/0x0003FFFF -sc STACK/Stack=STACK_AREA

-sc DATA/Data+INIT=RAM_AREA -sc CODE/Code=CODE_AREA

-sc START+CONST+@INIT=ROM_AREA

Also refer to the detailed memory maps in the appendix.

￿Always check the “map”-file (use the context menu in the project-view and select “open list file”) to see the used sections and addresses !
