CC2652R: Sysconfig configuration

Hi team,

SDK:4.20

Chip:CC2652

Example:simple peripheral OAD on chip 

I wanted to change the DC-DC to global LDO, so i unchecked the "Enable DCDC" option in the Sysconfig file, but this configuration didn't work.No ti_device_config.c file was generated, the registers in CCFG was not changed too.

I tried with example "simple peripheral",the same setting was working.Please guide me how the change the DCDC with example "simple peripheral OAD on chip", thanks.
