This chapter provides an overview of the boot and configuration process for Versal™ ACAP. This includes the boot device options, different stages of software involved in booting the platform and configuring different components.
The platform management controller (PMC) is responsible for boot and configuration and other post-boot tasks. A boot image, the programmable device image (PDI) is used to boot and configure Versal ACAP. A PDI contains platform loader and manager (PLM) executable, images, and configuration data. The PDI can be loaded from a boot device, such as an SD card, eMMC, OSPI, or QSPI, or it can be loaded through a slave interface, such as JTAG or SelectMAP. The BootROM starts the boot process and loads the PLM software that takes care of loading images and configuring the system based on images or configuration data in PDI.
