If you are migrating from UltraScale+™ device families, consider the following:

UltraScale+ device designs (without PS)
These devices contain integrated configuration logic that supports a set of configuration modes on power-up. With Versal ACAP, there are changes to the boot and configuration flows, which require the use of the CIPS IP instead of dedicated PL primitives.
Zynq UltraScale+ MPSoC and Zynq UltraScale+ RFSoC designs (with PS)
These devices have a PMU and CSU to manage and carry out the boot-up process. With Versal ACAP, there are changes in the boot flow methodology, which rely on the RCU and PPU in the PMC to manage and carry out the boot-up process.

For more information on the Versal ACAP boot modes, boot sequence, and boot image, see this link in the Versal ACAP Technical Reference Manual (AM011) , this link in the Versal ACAP System Software Developers Guide (UG1304), and the Bootgen User Guide (UG1283) .

The following table compares the primary boot and configuration modes of UltraScale+ devices with Versal ACAP.

  1. SelectMAP mode provides hardware flow control using a BUSY signal.
  2. Octal SPI and eMMC1 modes supersede the BPI and NAND modes used in previous architectures. Octal SPI and eMMC1 modes provide similar performance while reducing pin count.
