I would like to port Cortex-A9.
so i look up FreeRTOS Cortex-A9 Demo for QEMU guide and stucked..
c/c++ Eclipse CDT
clean:
-$(RM) $(SECONDARY_SIZE)$(OBJS)$(C_DEPS)$(ASM_DEPS)$(SECONDARY_FLASH)$(EXECUTABLES)$(SECONDARY_LIST)$(S_UPPER_DEPS) FreeRTOS_ARM_Cortex-A9.elf
-@echo ' '

and error message is
recipe for target `clean' failedmakefile/FreeRTOS_ARM_Cortex-A9_QEMU/Debugline 75C/C++ Problem

how can i create "FreeRTOS_ARM_Cortex-A9.hex "?.,..

I have no idea where you got the code and I have never built for Cortex-A9 myself nor used QEMU, so cannot give direct support other to say that there are three Cortex-A9 ports in the FreeRTOS Interactive site they may be able to help you as a reference:
