CC3120BOOST: SimpleLInkStudio + CC33xxEMUBOOST - trying to use PC as host MCU

Hi,

I have CC3120boost + CC33xxEMUBOOST and I'm trying to use any example from SimpleLinkStudio.
I flashed the service pack 3.3.0.0-2.0.0.0-2.2.0.4  from simplelink_studio_cc31xx_sdk_1_00_00_05/tools/cc31xx_tools/servicepack-cc3x20/sp_3.2.0.0_2.0.0.0_2.2.0.4.bin
I'm trying to use get_wheather example visual studio project from examples.

The board is connected to an Windows 7 machine (all drivers installed, I can see all 4 COM ports) via J6.

The output of the program is:

*****************************************************************
CC3100 Get weather App
1.2.0
*****************************************************************
Global lock is going to be deleated so wait (busyloop) for blocking threads to be released
----------------------------------------------------------> _globalLockMutexCounter = 0x0
******************************************************************
In osi_LockObjDelete(). All threads released. Closing Handle()
******************************************************************
 Error Code -2000
 Failed to configure the device in its default state, Error code: -2000
 

It doesn't work configured with SPI, nor UART (SL_IF_TYPE_UART).

When sl_Start function is called, the return value is 1 (ROLE_UNKNOWN) each time is called from configureSimpleLinkToDefaultState

Any hint/tip/help is highly appreciated.

Thanks,
Cezar
