Kinetis MK66, how overclock to 240Mhz

[luiHS]

 
Hi.

I want to apply overclock to a Kinetis MK66, to run at 240Mhz, I know it is possible because with the Teensy 3.6 I can apply an overclock at 192, 216 and 240Mhz, using the same microcontroller.

But I prefer to work with MCUXpresso, the problem is that I don't know how to configure it here, I have tried several combinations of the PLL but it always gives me error. The only sure  is that the maximum frequency of the VCO is 360Mhz.

Regards

Perhaps this is how?

You might be able to go faster and edit kinetis.h in hardware\teensy\avr\cores\teensy3... and edit where F_CPU == 120000000 and uncomment the line #define line with
setting F_BUS 120000000 (personally I have not tried running the bus at that speed...) So no idea if you might run into issues.

Its for Teensy using Arduino IDE, but I need to do with MCUXpresso. The libraries, and all the configuration files are totally different.

You probably noticed that it's spec'ed only up to 180MHz, so above that, I guess NXP doesn't guarantee anything. If that's just for a personal project, why not, but otherwise, not sure this is such a good idea.
