TMS570LC4357: problem with example_EPWM_ADC provided with TMS570LC4357

/** @example example_epwm_adc.c
*   This is an example which describes the steps to create an example application to generate 
*   PWM output with varying duty (depending on an external input)
*   
*   @b Step @b 1:
*
*   Create a new project.
*
*   Navigate: -> File -> New -> Project
*
*   @image html example_createProject.JPG "Figure: Create a new Project"
*
*   @b Step @b 2:
*   Configure driver code generation: 
*   - Enable ETPWM driver
*   - Enable ADC driver
*   - Disable others
*
*   Navigate: -> TMS570LCxx /RM57x -> Enable Drivers
*
*   @b Step @b 3:
*
*   Configure pinmux module
*       - Output pinmuxing  : Select eTPWM1A at ball B5
*       - Special pinmuxing : Use Alternate ADC 'Trigger Option-B'
*                             Enable TBCLK sync
*
*   Navigate: -> PINMUX ->Pin Muxing
*
*   @image html EPWM_OutputMux.JPG "Figure: Output Pinmuxing"
*
*   Navigate: -> PINMUX ->Pin Muxing
*
*   @image html EPWM_SplMux.JPG "Figure: Special Pinmuxing"
*
*   @b Step @b 4:
*
*   Configure ADC1 module
*       - Select Alternate trigger EPWM_B for ADC1 Event Group
*       - Select Pin 9 for Event group (Pin 9 is connected to a light sensor in HDK)
*
*   Navigate: -> ADC1 -> ADC1 Group Event
*
*   @image html EPWM_ADC_Config1.JPG "Figure: ADC configuration"
*
*   @b Step @b 5:
*
*   Configure EPWM module
*       - Enable ETPWM1 and disable others
*       - Set EPWM1 period as 5000ns
*       - Enable ADC SOCB generation with following configuration
*            - SOCBSEL : CTR_PRD
*            - SOCBPRD : 3
*
*   @b Step @b 6:
* 
*   Generate HALCGen code
*
*   @b Step @b 5:
*
*   Copy the source code below into your sys_main.c or replace sys_main.c with this file.
*
*   The example file can also be found in the examples folder: ../HALCoGen/examples
*
*   @note HALCoGen generates an empty main function in sys_main.c, 
*         please make sure that you link in the right main function or copy the source into the user code sections of this file.
*
*
*   The generated PWM signal can be monitored at pin B5. You can see the duty of the signal being 
*   changed by varying the light density near the light sensor
