    Hi Peter,

    Please refer to the C2000ware examples for the same. The 'usb_config_c28x' example project which has to be loaded on C28x side shows on how to control the peripheral clocks of CM. The project is available for all CM peripherals. For Ethercat, you can use 'SysCtl_setECatClk' driverlib function to control the clock divider values to achieve 25Mhz out of the PLL clock source
