u32 ClkWiz_Example ( XClk_Wiz *  IntcInstancePtr,
u32  DeviceId 
)

This function is the main entry point for the versal example using the XClk_Wiz driver.

This function will set up the system with interrupts handlers.

Parameters
DeviceIdis the unique device ID of the CLK_WIZ Subsystem core.
Returns
  • XST_FAILURE if the system setup failed.
  • XST_SUCCESS if successful.
int main ( )

This is the main function for XClk_Wiz rate example.

If the ClkWiz_Example function which sets up the system succeeds, this function will set the desired rate.

Parameters
None.
Returns
  • XST_FAILURE if the interrupt example was unsuccessful.
Note
Unless setup failed, main will never return since

u32 XClk_WaitForLock ( XClk_Wiz_Config *  CfgPtr_Dynamic)

This is the XClk_WaitForLock function, it will wait for lock to settle change frequency value.

Parameters
CfgPtr_Dynamicprovides pointer to clock wizard dynamic config
Returns
  • XST_SUCCESS if the lock occurs.
  • XST_FAILURE if timeout.
Note
None
