TMS320F28388D: Dual core clock configuration

Part Number: TMS320F28388D

Hello

I am using both cores for my applications and using TI driverlib examples.The external crystal oscillator is 20MHz.

In the device.h file, define the micro #define USE_20MHZ_XTAL, which configures the core to run at 200MHz.

Do I need to configure the clock for core2 also, or is that taken care of by the void Device_init (void) function in the device.c file of the core?

Thanks in advance

    Hi, 

    You need not configure the clock for core2. The PLL clock configuration is  owned by the CPU1 subsystem by default, so the Device_init() function will configure the clock for both cores.

    Best Regards
