EA LPC3250 SDRAM

I'm using the Embedded Artist LPC3250 development board. It has 64MB of external RAM. In my application, I need to create a few large global arrays. The internal memory of the 3250 is only 256KB so I'd like to relocate the zi-data or all the R/W data to the external SDRAM.

I used Project - Options - Target and added off-chip RAM1 and set it as the default. I then set "Use Memory Layout from Target Dialog" on the Linker tab. That creates a custom scatter file for me (shown below).

However when I build, the linker generates the error:
.\output\armd.sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST.

This error doesn't make sense to me because the section where First is used is the ROM portion.

Based on a SDRAM Phytec example, this project configuration and resulting scatter file should have worked.

Has anybody used the EA LPC3250 in this manner either relocating R/W or ZI to SDRAM? Does anyone have a suggestion on how to create the scatter file needed to put my data in SDRAM?
