CCS/PROCESSOR-SDK-AM437X: Compiler error

Part Number: PROCESSOR-SDK-AM437X

Tool/software: Code Composer Studio

Dear TI support,

I'm using processor_sdk_rtos_am437x_4_00_00_04 with idkAM437x board.

I'm trying to combine two examples.

1.) I generate example UART_BasicExample_idkAM437x_armExampleProject.

2.)Then i put in .cfg file (after load 'ti.board'):

var GPIOPackage = xdc.loadPackage('ti.drv.gpio');
GPIOPackage.Settings.socType = socType;
GPIOPackage.Settings.enableProfiling = true;

3.) Then in project properties add in "Directories" tab "${PDK_INSTALL_PATH}/ti/drv/gpio"

4.) Then i copy from C:\ti\pdk_am437x_1_0_7\packages\ti\board\diag\led\build\idkAM437x GPIO_LED_config.c because GPIO_v1_config was undefined...

5.) Now I get errors:
- undefined reference to `__cyg_profile_func_enter'

- undefined reference to `__cyg_profile_func_exit'

Console output:

makefile:148: recipe for target 'UART_BasicExample_idkAM437x_armExampleProject.out' failed

I know that this error are related with  "-finstrument-functions" flag but don't know how to used/solve error.
In other GPIO_LedBlink examples this flag is used in projects. If i try to used in UART example it fails with more errors.

Can you direct me what i need to change?

THANKS!

Best Regards,
Mare
