Hi,
I'm new here and it is my first time with LPCXpresso and the LPC1857 (Hitex Eval Board).

My project is an data logger and I wil store measured data form a accelerometer in the SDRAM temporary.
I have an example program for the Hitex Eval Board, it is called memtest, I will use this project as for testing the SDRAM and my project.

Now my question:
In the project properties from the memtest project the SDRAM (adress 0x28000000) is not listed in the Memory Configration Editor.
Only the internal Flash (0x14000000) and five RAMs (adress 0x10000000,0x10080000,0x20000000,0x20008000,0x2000c000) are listed.

Is it necassary that I add here the SDRAM?


On the website "http://support.code-red-tech.com/CodeRedWiki/EnhancedManagedLinkScripts  " I found that only the firts RAM in the Memory Configuration Editor is used for data or bss.
But I will use the SDRAM for saving the measured data in an Array.
Should I do this procedure?
Is it enough to add the SDRAM in the Memory Configuration Editor and the Linker manage the location from the usable storage itself?

Thanks

Stefan

Yes, you can add your SDRAM to the memory configuration editor. **But** you will also need to ensure that your application contains code that enables the SDRAM before it is used. This typically means that you will need to add a call to your SDRAM init code from within the cr_startup_lpc18xx.c file.

For more information on using the Memory Configuration Editor itself, please read the LPCXpresso 6 User Guide.
