Creating EA LPC3250 OEM Projects

CrossStudio for ARM supports the EA LPC3250 OEM board with loading and debugging applications into SDRAM and into the NAND flash.

To create a new EA LPC3250 OEM Board project

• Select the File | New | New Project menu item.
• Select Embedded Artists from the Manufacturers category list.
• Select the required project template type from the Project Templates list.
• Set the required project name and location directory.
• Click OK.

To build, load and debug an application running in SDRAM

• Select the project to work on by using the Project | Set Active Project menu option.
• Select the SDRAM placement by clicking on the project node in the project explorer.
• 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.

To load and debug an SDRAM application into the NAND Flash.

• Connect to the appropriate target in the target window.
• Right click on the project node in the project explorer and select Program NAND. Note that the NAND flash must have been initialised by downloading the NAND Flash Init application which is supplied in the loader solution.
• Start debugging by using Debug | Reset and Debug.

Embedded Artists LPC3250 OEM Project Specifics

Target Reset Script

The reset script for EA_LPC3250_OEM_Target.js supplies the reset script to set up the clocks and SDRAM. The reset script executes a program in IRAM to set up the clocks and SDRAM. This progam can be built with this project which in turn uses the NXP LPC3200 CDL which has been built into the library EA_LPC3250_OEM_lib.a.

Building EA_LPC3250_OEM_lib.a

The project (click to load solution) builds the NXP LPC3200 CDL library. This project requires the global macro LPC3250_SAMPLES to be defined to be the root of the installed NXP LPC3200 CDL, for example LPC3250_SAMPLES=c:/nxpmcu_lpc32xx_cdl_v201/nxpmcu/software.

Flash Loaders

The loaders (click to load solution) solution has projects to build the flash loader and secondary boot loader for the NAND Flash. This solution also contains the NAND flash initialisation application. Note that the library is used by the secondary boot loader to initialise the clocks and SDRAM.

Board Specific Files

The file EA_LPC3250_OEM.c provides a led and button pressed function.
