Execute FreeRTOS from RAM

Hi all I’m using ARM9_STR91X_IAR project , and I can execute it from FLASH successfully . Now I want to copy the image from flash to ram and execute it from ram . I have IAP bootloader to do copy work then jump to ram . There is a link file : lnkarm_flash.xcl I don’t know how to modify it to support execute from ram . Thanks.

This is an IAR file.  Take a look in your IAR installation directory for a RAM equivalent. Dave.

I refer some example file lnkarm_ram.xcl in the IAR installation directory . And I modify the FreeRTOS’s lnkarm_flash.xcl of the following : // Code memory in flash //-DROMSTART=0x00000000  Marked by Paul 96.4.25 //-DROMEND=0x00080000            Marked by Paul 96.4.25 //-DROMSTART=0x00080000 //-DROMEND=0x003FFFFF //-DVECSTART=ROMSTART            Marked by Paul 96.4.25 // Data memory -DRAMSTART=0x4000000 -DRAMEND=0x04018000 -DROMSTART=RAMSTART -DROMEND=RAMEND …. But when I make my workspace , it will generate some errors during linking : Building configuration: RTOSDemo – ARM Updating build tree… Linking Error[e16]: Segment DATA_Z (size: 0x123c8 align: 0x2) is too long for segment definition. At least 0x68e3 more  bytes needed.

You are now putting your executable code and data both in RAM and there is not enough space.

My Board only have 96 KBytes SRAM . So if I want put executable code and data both in RAM , it must need more then 96 KBytes of SRAM ?
