Package Installation Instructions

To install this support package into CrossWorks for ARM:

If you have not done so already, follow the MAC7100 CPU Support Package installation instructions.
Download Freescale_MAC7100EVB.hzq.
Click the Tools > Install Package menu option.
Select the Freescale_MAC7100EVB.hzq file in the file browser.
Click the Install button to install the package.

Using the MAC7100EVB Board Support Package

To create a new MAC7100EVB project

Select the File > New > New Project menu item.
Select Freescale from the Project Type list.
Select the required project template type from the Templates list.
Set the required project name and location directory.
Click OK.

CrossStudio for ARM supports the MAC7100EVB running applications running in both Single-Chip and Expanded mode.

To build and debug an application

Select the project to work on by using the Project > Set Active Project menu option.
Select the configuration you require by using the Build > Set Active Build Configuration menu option.
Build the project by using the Build > Build Project menu option.
Connect to the appropriate target in the target window.
Download and start debugging the current project by using Debug > Start Debugging.

If, during downloading, you see the error message Memory erase operation failed: no driver installed for memory range then it is likely that you have selected an Expanded mode configuration with the MAC7100 configured for Single-Chip operation or vice versa. Please ensure that you have selected the build configuration (Expanded or Single-Chip) that matches the operating mode of the MAC7100 (see below).

The following sections describe the MAC7100EVB support in more detail.

Operating Modes

Both Single-Chip and Expanded modes are supported. Please configure your board for the correct mode using the MODA and MODB DIP switches before downloading any application to the board.

Single-Chip Mode

The memory map for Single-Chip mode is:

Address Range	Description
00000000-0007FFFF	Internal Program FLASH
40000000-40007FFF	Internal SRAM
FE000000-FE007FFF	Data FLASH

Warning: Note that the MAC7100EVB User Manual specifically states that the external bus cannot be used in single-chip mode.

Expanded Mode

The memory map for Expanded mode is:

Address Range	Description
00000000-001FFFFF	External AM29F160DB-70 FLASH, 4 wait states on CS0
00200000-0021FFFF	External CY7C1021B-12 SRAM, 0 wait states on CS1
00300000-0030FFFF	SMSC LAN91C111, 0 wait states on CS2
40000000-40007FFF	Internal SRAM
FE000000-FE007FFF	Data FLASH

Target Startup Code

The default startup code is in $(StudioDir)/targets/Freescale_MAC7100/MAC7100_Startup.s. It contains the exception vectors and the default exception handlers for operating in Normal Single-Chip mode and Normal Expanded mode. When configured in Expanded mode, the project settings for the startup code will set up chip selects CS0, CS1, and CS2 for the memory map above, set the PLL to run at 50MHz and run the system clock from the PLL.
