@joe306 ,

I guess, here, PMU means Platform Management Unit.
If my guess is right then you can refer to Platform Management Unit (Chapter-6) in Zynq MPSoC TRM (UG1085)

The Zynq® UltraScale+™ MPSoC includes a dedicated user-programmable processor, the
platform measurement unit (PMU) processor for power, error management, and execution
of an optional software test library (STL) for functional safety applications.


The PMU performs the following set of tasks:
• Initialization of the system prior to boot.
• Power management.
• Software test library execution (optional).
• System error handling.

For the example design please refer ZCU-106 TRD.

I hope the above information would help.

BR,
Kuldeep

Hi @joe306 ,

Could you share the purpose/aim for which you require example on the Power Management Unit?
It would help in providing appropriate solution. 

Are you looking for reprogramming power controllers?

 

BR,
Kuldeep

Hello, thank you for responding to my message. I am new to the Xilinx Tools and also the MPSOC. I am currently taking some On-Demand classes from Xilinx and they mention the PMU. I have done the Hello World example and would like to learn how to use the PMU.

 

Thank you,

Joe

Hello, I didn't see the PMU example, what page is it on? Is this the correct document #UG1250?

Are there any instructions/documentation on the PMU Application Template? I am using the latest Vitis tools.

 

Thank you

Hi @joe306 

 

The Platform Management Unit Firmware (PMUFW) is a part of the software stack on Zynq® MPSoC devices that users expect to work out of the box, and so don't tend to pay much attention to until something goes wrong.

However, as the name states, this software manages the whole platform, so it has a huge impact on a lot of use cases that you might be using right now.

For more details, please refer blog : Zynq MOSoC PMU Firmware - Build and Run

 

Best Regards,
Kuldeep
