Hai and thanks in advance.

For a custom board design based on KW30Z, we are not able to get DC output in VDD_1P8 and VDD_1P45 pins. We have not programmed the SoC and we are using buck mode configuration same as in FRDM-KW40Z and we expected 1.8V and 1.45V at VDD_1P8 and VDD_1P45 respectively upon pressing the PSWITCH.

But unfortunately we could not get the expected output. Can anyone guide us on this and is it correct to set the DC-DC converter in buck mode before programming a fresh KW30Z?
