TMS320F28377D: Driver example don't work on controlCARD R1.1

Hi, 

I am evaluating the F2837x with the controlCARD R1.1 and C2000Ware_3_03_00_00 examples.

I downloaded the LED blinky example and run. 

But it seems to stuck the board. 

When I check the suspend button while running, it stops at below line in sysctrl.c

//
// Wait for the SYSPLL lock counter
//
while((HWREGH(CLKCFG_BASE + SYSCTL_O_SYSPLLSTS) &
SYSCTL_SYSPLLSTS_LOCKS) == 0U)
{
;
}
