CC2642R: COMPA Sensor Controller Studio x SCIF Framework

Hi,

I created a project in SCS to use the COMPA and COMPA event trigger. To do that a linked the COMPA to the DIO30. DIO30 is an ADC powered with 3.3V. My trigger is set to occurs when the DIO30 falling edge. Everything works fine in SCS. I can see the event and the compaValue that changes.

But when I created a project in CCS (To do this I used the empty project in the skd drivers folder) and included the scif framework generate by the SCS, the compaValue starts with 0 (it should starts with 1 as we can see in the SCS) and I can't see the event happen.

When I look the DIO30 input, the value read is 0:

This is my code for the version sdk 3.40:

#include "ex_include_tirtos.h"
#include "scif.h"


#define BV(n)               (1 << (n))


// Display error message if the SCIF driver has been generated with incorrect operating system setting
#if !(defined(SCIF_OSAL_TIRTOS_H) || defined(SCIF_OSAL_TIDPL_H))
    #error "SCIF driver has incorrect operating system configuration for this example. Please change to 'TI-RTOS' or 'TI Driver Porting Layer' in the Sensor Controller Studio project panel and re-generate the driver."
#endif

// Display error message if the SCIF driver has been generated with incorrect target chip package
#ifndef SCIF_TARGET_CHIP_PACKAGE_QFN48_7X7_RGZ
    #error "SCIF driver has incorrect target chip package configuration for this example. Please change to 'QFN48 7x7 RGZ' in the Sensor Controller Studio project panel and re-generate the driver."

I tried to generate the code with the Sensor Controller Studio: Version 2.6.0.132 (simplelink_cc13x2_26x2_sdk_3_40_00_02) and 2.9.0.208 (simplelink_cc13xx_cc26xx_sdk_6_10_00_29).

Code Composer Studio Version is 11.1.0.00011.

Thanks in advance,
