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.
This blog entry is intended to be the starting point of a series where I will be covering different aspects of the PMU Firmware, from buildling or debugging it up to discovering its role in different system use cases.
