PLL is not lcoked in S32K148 EVB board(MCAL with sample application)

[igunasek]

hi,

I have just debug the code in uc, System PLL valid bit always false. I am using sample application provided by Nxp, but this bit states like "system OSC clock error ".

I have no idea about this error.

Please support for this issue

For NXP(S32K148EVB-Q176) hardware the “High Gain Oscillator Select” parameter of McuSOSCClockConfig must be unchecked, as it is in our release configuration. With this the PLL will work.

 

For more details please see the S32K1XX data sheet, chapter 6.2.1 and the schematic of S32K148 EVB, XTAL schematic R64 is not populated.
