TMS320F28379D: Configuring CPUx clocks

Dainius Narsutis57

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hi,

Very new to the Delfino family, but working on a project requiring dual Core processing. I've done my best reading the technical manual but I still have some questions which I am sure you will find answers to them obvious. So here it is:

- In the Technical Ref Manual it states that the CPU1 configures the clocks, does it need to configure clock of the CPU2 too? Or is it responsibility of the CPU2 to take the PLLSYSCLK and configure itself?

- If the CPU1 configures the clocks, does it also need to configure the Peripheral clocks of the Peripherals that the CPU2 will be using?

Kind regards

Hi,

- In the Technical Ref Manual it states that the CPU1 configures the clocks, does it need to configure clock of the CPU2 too? Or is it responsibility of the CPU2 to take the PLLSYSCLK and configure itself?

Clock for CPU1 and CPU2 are same. There is no separate configuration for CPU2.

- If the CPU1 configures the clocks, does it also need to configure the Peripheral clocks of the Peripherals that the CPU2 will be using?

Each CPU has it's own PCLKCRx registers. So once CPU1 allocate peripherals to CPU1 or CPU2, respective CPU need to enable clock for the peripherals assigned to it.

Is there a guide that explains how to configure the CPUs step by step?

Details are in device TRM. For programming steps you can refer examples provided in C2000Ware.
