Our team is applying MCU STM32F207 to 800x480 touch LCD. We have connected external flash memories both NAND and NOR to our board for huge image data. We want to use MCU RAM for program codes and external memories for the image data.

Can we get the information about how to compile with IAR EWARM compiler for this?

Thanks and Regards

for

information

on how to configure

the .icf file you can read the template included in ST standard library package (I have the STM32F4 library I don't know the STM32F2 serie but I think you can found  the template also for  this micro) The readme file included in template directory say:  - project .ewd/.eww/.ewp: A pre-configured project file with the provided library                            structure that produces an executable image with IAR                            Embedded Workbench.                   - stm32f4xx_flash.icf : This file is the IAR Linker configuration file used to                          place program code (readonly) in internal FLASH and data                          (readwrite, Stack and Heap)in internal SRAM.                          You can customize this file to your need.                                                                                  - stm32f4xx_flash_extsram.icf: This file is the IAR Linker configuration file                                 used to place program code (readonly) in internal                                 FLASH and data (readwrite, Stack and Heap)in                                 external SRAM. You can customize this file to your need.      - stm32f4xx_flash_extsdram.icf: This file is the IAR Linker configuration file                                  used to place program code (readonly) in internal                                  FLASH and data (readwrite, Stack and Heap)in                                  external SDRAM. You can customize this file to your need.                                                                   - stm32f4xx_ram.icf:  This file is the IAR Linker configuration file used to                        place program code (readonly) and data (readwrite, Stack                        and Heap)in internal SRAM.                        You can customize this file to your need.
