Lpc11u68 can't lock PLL

[sergiofernandez]

I am getting totally crazy, my board was woring perfectly for some years untill now, and suddenly any program can't pass from this:

/* Wait for PLL to lock */
while (!Chip_Clock_IsSystemPLLLocked()) {}

I need to solve this problem.

Than you.

Hi Sergio Fernandez,

    What the clock source of your PLL? Is it from oscillator?

   If yes, please check your external crystal with oscilloscope, whether it is oscillating or not? or you can change it to the internal IRC, and try again.

Have a great day,
Kerry
