Creating TiRTOS as static library for CC2650

Other Parts Discussed in Thread: CC2650, CC3200

Hello,

currently we are about to build an application for the CC2650. Therefore we need the TiRTOS as a static library to link against because on our build-server we do not have any xdctools.

In the CC3200-sdk, the oslib project contains a "libtirtos.a" under gcc/exe. Now we are interested in how we can build this library on ourselves for the CC2650. We saw that both CC32xx and cc26xx use the simplelink_tirtos. Are they the same?

With the Makefile under oslib/gcc, we can build the libFreeRTOS.a. When running Makefile_oslib_tirtos, at the moment we get the error, that include <xdc/std.h> cannot be found.

Now we would like to now how we could get this running, so that we can build a static tirtos.a library to use for the CC2650.

 

Best regards

    Hi,

    What version of TIRTOS are you using?

    In the User_Guide.pdf there is a section titled "Rebuilding TI-RTOS".   it shows how you can rebuild TI-RTOS.  However, I think you need xdctools to rebuild this.

    Hi Judah,
    we installed tirtos_simplelink_setupwin32_2_13_01_09.exe.

    We copied an existing CC32xxSDK and and changed following Makefiles to CC2650:
    ./oslib/gcc/Makefile_oslib_tirtios:
    #LFLAGS = -mcpu=cortex-m4 -march=armv7e-m -mthumb -mfloat-abi=soft -Wl,-T,$(OTHERPROJECT)/linker.cmd -lgcc -lc -lm -lrdimon LFLAGS = -mcpu=cortex-m3 -march=armv7e-m -mthumb -mfloat-abi=soft -Wl,-T,$(OTHERPROJECT)/linker.cmd -lgcc -lc -lm –lrdimon

    ./tools/gcc_scripts/makedefs_ti_rtos:
    #XDCTARGET = gnu.targets.arm.M4
    XDCTARGET = gnu.targets.arm.M3
    #PLATFORM = ti.platforms.simplelink:CC3200
    PLATFORM = ti.platforms.simplelink:CC2650F128
    #CFLAGS = -mcpu=cortex-m4 -march=armv7e-m -mthumb -mfloat-abi=soft -Dgcc -DUSE_TIRTOS -DCCWARE -DSL_FULL -DSL_PLATFORM_MULTI_THREADED -I$(CCWARE_INSTALLATION_DIR) -I$(CCWARE_INSTALLATION_DIR)/inc -I$(CCWARE_INSTALLATION_DIR)/driverlib -I$(CCWARE_INSTALLATION_DIR)/oslib -I$(CCWARE_INSTALLATION_DIR)/simplelink -I$(CCWARE_INSTALLATION_DIR)/simplelink/Include -I$(CCWARE_INSTALLATION_DIR)/oslib -ffunction-sections -fdata-sections -g -gstrict-dwarf –Wall
    CFLAGS = -mcpu=cortex-m3 -march=armv7e-m -mthumb -mfloat-abi=soft -Dgcc -DUSE_TIRTOS -DCCWARE -DSL_FULL -DSL_PLATFORM_MULTI_THREADED -I$(BIOS_INSTALLATION_DIR) -I$(XDCTOOLS_INSTALLATION_DIR)/packages -I$(XDCTOOLS_INSTALLATION_DIR) -I$(CCWARE_INSTALLATION_DIR) -I$(CCWARE_INSTALLATION_DIR)/inc -I$(CCWARE_INSTALLATION_DIR)/driverlib -I$(CCWARE_INSTALLATION_DIR)/oslib -I$(CCWARE_INSTALLATION_DIR)/simplelink -I$(CCWARE_INSTALLATION_DIR)/simplelink/Include -I$(CCWARE_INSTALLATION_DIR)/oslib -ffunction-sections -fdata-sections -g -gstrict-dwarf -Wall
    #LFLAGS = -mcpu=cortex-m4 -march=armv7e-m -mthumb -mfloat-abi=soft -nostartfiles -static -Wl,-Map,$(NAME).map -Wl,--gc-sections -Wl,-T,cc3200.lds -Wl,-T,$(OTHERPROJECT)/linker.cmd -ldriver -lsimplelink -ltirtos -lgcc -lc -lm -lrdimon -L$(CCWARE_INSTALLATION_DIR)/driverlib/gcc/exe -L$(CCWARE_INSTALLATION_DIR)/simplelink/gcc/exe -L$(CCWARE_INSTALLATION_DIR)/os_lib/gcc
    LFLAGS = -mcpu=cortex-m3 -march=armv7e-m -mthumb -mfloat-abi=soft -nostartfiles -static -Wl,-Map,$(NAME).map -Wl,--gc-sections -Wl,-T,cc3200.lds -Wl,-T,$(OTHERPROJECT)/linker.cmd -ldriver -lsimplelink -ltirtos -lgcc -lc -lm -lrdimon -L$(CCWARE_INSTALLATION_DIR)/driverlib/gcc/exe -L$(CCWARE_INSTALLATION_DIR)/simplelink/gcc/exe -L$(CCWARE_INSTALLATION_DIR)/os_lib/gcc

    With following command a static library ./exe/libtirtos.a was generated:
    /c/ti/ccsv6/utils/bin/gmake.exe -f Makefile_oslib_tirtos

    Until now we could not check whether that library can be used, because we do not yet have a simple cmake-project working.

    Best regards,
    Thomas

    Sounds like you found a solution? I will go ahead and closed this thread if that is the case.
