FRDM K64 can’t run at 120Mhz

mikesmith · ‎11-01-2014

Hi, I’m trying to use my K64 with a bareboard Project. So I decided to configure the system clock. I wanted to run the K64 at 120 MHz in PEE mode, but I failed, somebody can help me? I attached the code I’ve been using; My code works for frequencies below 66 MHz (at the output of MCGOUTCLK). I’m using the mcg diver that is provided by freescale.

Regard

Note: If I configure the PLL with correct values (PLL0_PRDIV=25 and PLL0_VDIV=50) for 120 Mhz the debugger gets lost

Hi,

It is very probable that you need to set the correct values for the OUTDIV fields in the SIM_CLKDIV registers.

Regards,

Alejandro

The easiest way is if you have a look what settings Processor Expert is using. Have a look here:

FRDM-K64F at Maximum Speed of 120 MHz | MCU on Eclipse

I have pasted the code of CPU_Init.c so you can see what it does.
