Dear expert,

I am asking for customer.

They have the need for PMBus Multi-Master,

does our F280025C compatible in the HW and SW?

Also, do we have any document for this or example code for PMBus Multi-Master?

Eric,

We only support multi-controller support on the I2C module. Could you please provide more details on the PMBus application, so we can look into this support for roadmap devices?

Best Regards,

Aishwarya

Eric,

Sharing the offline conversation here for visibility:

In addition to PMBUS starter code located at: C:\ti\c2000\C2000Ware_5_04_00_00\libraries\communications\PMBus, here is an example flow to implement a multi controller flow:

The sequence to be followed would be to disable, enable, and configure/initialize the mode (Controller/Target) using driverlib functions:

PMBus_disableModule()
PMBus_enableModule()
PMBus_initTargetMode() / PMBus_initControllerMode()

Best Regards,

Aishwarya
