Getting Started

2.1Setting up a standalone ARM Integrator/CM940T

To set up the core module as a standalone development system:

1.Optionally, fit an SDRAM DIMM.

2.Supply power.

3.Connect Multi-ICE.

2.1.1Fitting an SDRAM DIMM

You should fit the following type of SDRAM module:

•PC66- or PC100-compliant 168pin DIMM

•unbuffered

•16MB, 32MB, 64MB, 128MB or 256MB.

To install an SDRAM DIMM:

1.Ensure that the core module is powered down.

2.Open the SDRAM retaining latches outwards.

3.Press the SDRAM module into the edge connector until the retaining latches click into place.

Note

The DIMM edge connector has polarizing notches to ensure that it is correctly oriented in the socket.

2.1.2Using the core module without SDRAM

The core module can be operated without SDRAM because it has 256KB of SSRAM permanently fitted. However, in order to operate the core module with ARM debuggers, you must change the internal variable $top_of_memory from the default setting of 0x00080000 (= 512KB) to 0x00040000 (= 256KB) before running programs that are linked with the standard libraries.

For further information about ARM debugger internal variables, refer to the Software Development Toolkit Reference Guide.
