C:\ti\mspware\MSPWare_2_30_00_49\driverlib\examples\MSP432P4xx\uart\uart_pc_echo_12mhz_brclk.c linking problem

Su Jin

Other Parts Discussed in Thread: MSPWARE

I tried to compile the example code, it seems OK, but linking could not generate an executable obj.

Including "cs.h", which has definition of function CS_setDCOCenteredFrequency(...), does not help.
Thank you very much in advance for your help.

Below are the console error messages.

Hi Su Jin,

After reviewing your linker command line, the problem is that you are not linking the msp432p4xx_driverlib.lib

My project does link it.

'Invoking: MSP432 Linker'

"C:/ti_6.1.0.000102/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/bin/armcl" -mv7M4 --code_state=16 --float_support=FPv4SPD16 --abi=eabi -me --advice:power=all -g --gcc --define=__MSP432P401R__ --define=TARGET_IS_MSP432P4XX --define=ccs --diag_wrap=off --diag_warning=225 --display_error_number -z -m"uart_pc_echo_12mhz_brclk.map" --stack_size=512 -i"C:/ti_6.1.0.000102/ccsv6/ccs_base/arm/include" -i"C:/ti_6.1.0.000102/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/lib" -i"C:/ti_6.1.0.000102/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/include" --reread_libs --display_error_number --diag_wrap=off --warn_sections --xml_link_info="uart_pc_echo_12mhz_brclk_linkInfo.xml" --rom_model -o "uart_pc_echo_12mhz_brclk.out" "./msp432_startup_ccs.obj" "./uart_pc_echo_12mhz_brclk.obj" "C:/ti/msp/MSPWare_2_30_00_49/driverlib/driverlib/MSP432P4xx/ccs/msp432p4xx_driverlib.lib" "../uart_pc_echo_12mhz_brclk_ccs.cmd" -l"libc.a"

Not sure why it was not included when you imported the project, you should have something like this when you:

The easiest fix is to add the MAP_ to the functions that the linker is not finding.

    /* Selecting P1.2 and P1.3 in UART mode */
    MAP_GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P1,
            GPIO_PIN1 | GPIO_PIN2 | GPIO_PIN3, GPIO_PRIMARY_MODULE_FUNCTION);

    /* Setting DCO to 12MHz */
    MAP_CS_setDCOCenteredFrequency(CS_DCO_FREQUENCY_12);

Or you could manually add the driverlib.lib into your project.

Best regards,

David

Thank you very much.

Adding MAP_ doesn't work.

I agree you. But there are two points indicate it may be not true. (1) the compiler not the linker should show the error on its line "#include driverlib.h";

and (2) I have manually add the file in the link path, see the screenshot:

I really do not know what's wrong.

Thank you very much for your time again.

Hi Su,

You will need to include the library as part of your project, the above screenshot only includes is for the header file search path. So you have a couple of options.

Right click on your project > Add Files... And look for the "msp432p4xx_driverlib.lib", it should be located in "C:\ti\msp\MSPWare_2_40_00_37\driverlib\driverlib\MSP432P4xx\ccs"

Or under your project options, please add it in here:

Regards,

David

Yes, after add the lib in my project, no more problem.

Thank you very much, David. I really appreciate your help.
