Hello,
you will find a software example for the RM9200-DK for the IAR IDE at the following address:
ftp://at91supp:support@81.80.104.162/OUT/IAR/, file AT91RM9200-BasicTools-IAR4_11A-1_1.zip
This software example has been build for the RM9200-DK, so you will probably have to adapt the initialization files for the RM9200-EK. But, it should help you to get started.
For info, I have checked this software package with the RM9200-EK and you can use it "AS IS" if you want to debug in internal RAM by selecting the workspace Debug 0x200000.
If you want to debug from internal SDRAM using the workspace Debug 0x20000000, you have to adapt it to the SDRAM available on the RM9200-EK board.
Hope this help.
Rgds
