MPC5554 cook book includes a project that uses FMPLL.In the initialization source code,there is a loop in which there is check for "LOCK" bit of "FMPLL.SYNSR" register as the main condition.The bit never sets to 1 and so the loop never ends.
Do i need to make some change in source code in order for PLL to occur or do i need to do something else in order to execute it properly.

can some one please answer this query...it straight out of the book code..still it is not working...any suggestion or solution...
Hi khurram712,
I've just tested FMPLL example and seems to work correctly with EVB MPC5554DEMO.
Do you use a custom board or Freescale EVB?
The example expects 8Mhz external crystal. What crystal do you have?
