I am using FRDM-K64F as a prototype board for RTC test. I used PE to program rtc, but the clock seems not running. I am using an oscilloscope to check the 32K crystal. I can see both the 8MHz and 25Mhz on board. But no oscillation on 32K crystal at all.
Has anyone worked on FRDM-K64F RTC before? I had three FRDM boards and none has oscillation. Do I need pop those caps and resistors based on the schematics
