FreeRTOS Demo in Eclipse Mars and GNU Tools ARM Embedded 5_2_2015q4 for CP-JR ARM7 LPC2368

Posted by christianhaller on February 17, 2016

Hello, I opended the following project FreeRTOSV8.2.3.exe > FreeRTOS > Demo > ARM7LPC2368Eclipse with current eclipse-cpp-mars-1-win32-x8664 and GNU Tools ARM Embedded gcc-arm-none-eabi-52-2015q4-20151219-win32.exe and GNU ARM Eclipse Build Tools gnuarmeclipse-build-tools-win64-2.6-201507152002-setup.exe under Windows 7 x64

While installation I replaced all . by _ because I read that . in path could cause problems.

I get the following error: Program "arm-elf-gcc" not found in PATH

Resolution from http://stackoverflow.com/questions/20412100/discovery-options-in-eclipse-c-c Kepler hides "Discovery Options" by default. Go to Window->Preferences-> C/C++ > Property Pages Settings and check display discovery option page. Then, open your project preferences and change arm-elf-gcc to arm-none-eabi-gcc like the rest.

I tested this but I couldn't find the option.

Resolution from https://wiki.ubuntuusers.de/Archiv/GNUARM-Toolchain/ Das PPA installiert arm-none-eabi-gcc, nicht arm-elf-gcc wie im Rest des Tutorials. Das Target arm-elf wird ab GCC 4.8 nicht mehr unterst├╝tzt. In der Bedienung unterscheiden sich arm-none-eabi-gcc und arm-elf-gcc nicht.

GCC after 4.8 no longer support arm-elf-gcc.

What can I do now?

This is my board: http://www.micro4you.com/files/lpc2368/ARM7_LPC2368.pdf I plan to flash the generated .hex-file via UART-0 with Flash Magic.

Thank you.

Do you have the arm-none-eabi-gcc compiler installed on your host and in the system path? It is not part of the Eclipse install and installed separately.

Yes I wrote: GNU Tools ARM Embedded gcc-arm-none-eabi-5_2-2015q4-20151219-win32.exe

C:Usersblueicehaller>arm-none-eabi-gcc arm-none-eabi-gcc: fatal error: no input files compilation terminated.

Can I get it to work if I create symlink named arm-elf-gcc to gcc-arm-none-eabi ?

That means the compiler is installed. What is the issue you have then? If it is calling arm-elf-gcc but the compiler is arm-none-eabi-gcc then you will need to update the project to use the right compiler.

I believe I found the location where I have to set this, see "Properties for RTOSDemo.png" I also changed line 60 ~~~~ 55 RTOSSOURCEDIR=../../../Source 56 DEMOCOMMONDIR=../../Common/Minimal 57 DEMOINCLUDEDIR=../../Common/include 58 UIPCOMMONDIR=../../Common/ethernet/uIP/uip-1.0/uip 59 60 CC=arm-none-eabi-gcc # previous value: arm-elf-gcc 61 OBJCOPY=arm-elf-objcopy 62 LDSCRIPT=lpc2368.ld ~~~~ Should I change something other than "Compiler invocation command"?
