Memory allocation failure with heap_3.c

I find that heap_3.c is used in the demo of AT91SAM9XE, but I can not successfully port FreeRTOS to AT91SAM9G20 with heap_3.c in IAR. However, I have ported FreeRTOS to AT91SAM9G20 successfully with heap_2.c. If I want to use heap_3.c, what setting should I modify in IAR? Or what codes should I modify? Thanks for instructions!

heap_3 is the only heap option that does not use the configTOTAL_HEAP_SIZE configuration file setting, and instead uses the heap allocated by the IAR linker - which is set by editing the project options inside the Embedded Workbench IDE. If you are not sure how to set the heap size using the IAR tools then please refer to the compiler’s user guide/manual.
