Release Notes




Using the MAC7111LCEVB Board Support Package

To create a new MAC7111LCEVB project

CrossStudio for ARM supports the MAC7111LCEVB running applications running in both Single-Chip and Expanded mode.

To build and debug an application

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 MAC7111LCEVB support in more detail.

Operating Modes

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

Single-Chip Mode

For Single Chip Mode programming you must remove the FLASH-EN jumper and move the MODB switch to the OFF position. 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

For Expanded Mode programming you must insert the FLASH-EN jumper on J5, insert the FLASH write enable jumper on J14, and move the MODB switch to the ON position. Note that J14 is not populated on the board as delivered by Freescale.

The Freescale MAC7111LCEVB Users Manual (Revision 1.1, October 2004) schematics indicate that the board is delivered with an Am29F200B device fitted. However, in our experience the production board has an Am29F400BB device fitted. This device is pin-compatible with the Am29F200B but has twice the memory. The MAC7111LCEVB loader will support loading to a board with either an Am29F200B or Am29F400BB device fitted. If your board is populated with any other device, you will need to modify the loader appropriately.

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.
