  • Hi Dan,

    If you are using VisualDSP please refer the below path to Initialize the PLL configuration commands.
    <Installation Path> :\Program Files (x86)\Analog Devices\VisualDSP 5.1.2\214xx\Examples\ADSP-21489 EZ-Board\Power_On_Self_Test\system_init.c

    Or if you are using CCES, please refer the example in Board Support Package (BSP). The BSP can be downloaded from the below link.
    download.analog.com/.../ADI_ADSP-21489_EZKIT-Rel1.0.0.exe

    After installing BSP, please navigate as given below.
    <Installation Path> :\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Power_On_Self_Test\src\system_init.c
