TMS320F28386S: Master core

Hi John,

John Hite said:

The sysconfig tool has a master core setting.

Is this mentioned in TRM?

Actually, SysConfig only supports configuration of CPU1 and its CLA core. It does not support CM or CPU2.

Muticore Sysconfig will be available in next release of C2000Ware version 4.03.00.00 which is expected to be release in February 23. But it will only support CPU1, CPU2 and corresponding CLAs. But it will not support configuration of CM core.

OK sysconfig does not support it. 

But from what I infer from examples it still needs to be set if CM is to control a gpio pin. If I do not set it with

    GPIO_setMasterCore(15, GPIO_CORE_CM);

gpio writes to this pin from the CM do not work.

Does it apply to other peripherals?

Since it is a setting that needs to be considered I think it should be documented so one does not need to make inferences from examples.

John,

Configuration for GPIO master core is available within CPU1 GPIO condig. Please see the screen below.

Hi Santosh,

I think you are missing my point.

I am not asking how to configure master core. I am asking what it is. There is no discussion of it that I can find. Does it only apply to gpio or other peripherals too?
