LMK05318EVM: I meeet some problems and want to connect with enginner who is familiar with the lmk05318evm

Hello,
please describe where you are getting stuck when following the quick start information fro the EVM user guide so we can better assist you

Hello,
I think the start of lmk05318 should follow the pll intialization sequence but I meet problem in the first and second steps,VCO calibration and aplls locked(free run from xo)
I used the plate-crystal calibration as the main clock, and both the formula and the central frequency of vco1 met the requirements of entering freerun mode. However, when the state of the led light was adjusted to pll1 vco calibration active, it did not light up. Even if manually restart by pll1powerdown, the led light representing pll1 vco calibration active only flicker once.However, when I cascade apll2 xo, the light from the pll2 vco calibration active is turned on, and when I cascade apll2 to apll1, the light from the pll2 vco calibration active is also turned off,so I suspect the apll1 of my evm has problem.
In addition, after I connected the reference and use apll1 cascade with dpll. When the led light indication was the default, the DPLL lock requirement could be met,(the light of dpll loss of locked is not high,and dpll holdover is not high)but when the led light was turned back to indicate pll1 vco calibration active and pll1 lock detected (lol*), which were not on.And the output waveform is not in phase with my reference waveform.So now I really doubt that there is something wrong with the hardware of the development board. Can you help me?Thanks a lot.
