1. GPIo toggle is 100 nano - i flatten the the call to GPIO as a macro
2. Nop operation takes 64 nano - at 120 mega it should be faster , no?
3. The get sysclock(core clock) does return 120 mega.
But i think that the chip is not working in 120 mega,
How do i check that FRDM K64 does running in 64 mega?
i saw some threads about it , that imply that there are issue with the system clock.
Can some one from NXP please help on this Topic?
What should be done if so , in hardware and software to run it at maximum speed?
