RTOS/MSP432E401Y: AES Driver initialization issues

Part Number: MSP432E401Y

Tool/software: TI-RTOS

Hi,
I'm working on a MSP432E401Y with TI RTOS and the SDK 2.10.00.17. I succesfully tested the aes_example without the RTOS.

In RTOS project it seems that these clock configuration APIs generate problems in debug:

/* Disable clock to CCM0 and reset the module from  system control and then
             enable the clock. */
    MAP_SysCtlPeripheralDisable(SYSCTL_PERIPH_CCM0);
    MAP_SysCtlPeripheralReset(SYSCTL_PERIPH_CCM0);
    MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_CCM0);

    /* Wait for the peripheral to be ready. */
    while(!MAP_SysCtlPeripheralReady(SYSCTL_PERIPH_CCM0))
    {
    }

I tryed to insert them in startup but nothing change:

var Startup = xdc.useModule('xdc.runtime.Startup');
/*
 * Default value is family dependent. For example, Linux systems often only
 * support a minimum period of 10000 us and multiples of 10000 us.
 * TI platforms have a default of 1000 us.
 */
Clock.tickPeriod = 1000;

/* install a "first function" */
Startup.firstFxns[Startup.firstFxns.length++] = '&AES_Init_First';

any idea ?

thank you,

Tommaso
