Is RM48x + HalcoGen + Code Composer Studio + GCC toolchain supported

Other Parts Discussed in Thread: HALCOGEN

I am not sure if this is the correct forum to post, but before I go into deeper details, I just wanna know in general:

Is there official support for using Halcogen and CCS for GCC toolchain for an RM48x based embedded project? I am asking because when I start a new project and add files form Halcogen, I am getting errors when building the assembler source files. I am only having trouble when using GCC toolchain. The TI toolchian works well.

Kind regards,

Erik

    Erik,

    yes we do support GCC too chain with halcogen for RM48x.

    If you could post little more details about the issue, I can certainly get some help from our Halcogen team.

    Karthik,

    That's good news.

    Ok, here is what I did.

    1. I Created a new CCS Project with these Settings:

    2. I started a new Halcogen Project, configured for dropping the generated code directly into my project folder. I used the following Settings:

    Device: RM48L952PGE

    Name: Test_GCC

    Location: D:\CCS_Workspace\TestGCC

    Create Directory for project NOT checked

    Tools: GCC Tools.

    3. I added the include directories to the project settings of CSS.

    4. After building the project, I get these errors:

    'Building file: ../source/sys_core.s'
    'Invoking: GNU Compiler'
    "D:/Programme/ti/ccsv6/tools/compiler/gcc-arm-none-eabi-4_8-2014q3/bin/arm-none-eabi-gcc.exe" -c -I"D:/Programme/ti/ccsv6/tools/compiler/gcc-arm-none-eabi-4_8-2014q3/arm-none-eabi/include" -I"D:/CCS_Workspace/Test_GCC/include" -g -gdwarf-3 -gstrict-dwarf -Wall -MMD -MP -MF"source/sys_core.d" -MT"source/sys_core.d" -o"source/sys_core.o" "../source/sys_core.s"

    Any help would be greatly appreciated.

    Thanks a lot,

    Erik

    Hello Erik,

    It should be something to do with enabling the vectored floating point option I guess.

    Will request someone from Halcogen team to help with this.

    Karthik,

    I agree with your evaluation of the issue. Let's hope the Halcogen team can come up with a suggestion soon.

    Reagrds,

    Hi Erik,

    Minimal Compile option that must be provided for compiling on CCS with GCC compiler.

    -mcpu=cortex-r4 -march=armv7-r -mfloat-abi=hard -mfpu=vfpv3-d16 -I"C:/ti/ccsv6/tools/compiler/gcc-arm-none-eabi-4_8-2014q3/arm-none-eabi/include"  -g -gdwarf-3 -c -mlittle-endian -r

    When creating the new project, on the top of the popup window for project properties you would have seen a warning " Selected device does not currently provide project initialization details for the GNU toolchain. The project may require further manual set up."
