Hello,

 

I am using a MK22FN512VLH12 with and external oscillator and it does not run.

 

Since I had no luck with mbed I tried tried with processor expert and KDS2.0.0 and if I use internal clock it works OK but if I use external crystal no luck :-(

I have used a 8Mhz cristal .as well as the 32kHz for the RTC with the capacitors and resistors specified in the user guide. (FRDMK22UG.pdf)

 

My programs work on the FRDMK22

 

 

Can you help please.
