Terasic Mercury A2700 User Manual page 17

The factory setting of the SoC boot of the Mercury A2700 Accelerator Card is the
FPGA Configuration First Mode. The architecture is shown in the
storage mediums are used. The system needs QSPI flash on Apollo Agilex as SDM
flash for booting.
Figure 2-6 FPGA Configuration First Dual SDM and HPS Flash
The QSPI flash memory has the following boot data for the first part of the SoC FPGA
configuration:

Configuration firmware for the SDM

FPGA I/O and HPS external memory interface (EMIF) I/O configuration data

FPGA core configuration data

HPS First-Stage Boot Loader(FSBL) code and FSBL hardware handoff binary
data
Meanwhile, Terasic provides the micro SD card with built-in image data as HPS flash,
which is used for HPS boot in the later part. The micro SD card stores the following
data:

Second-Stage Boot Loader(SSBL)

Kernel Image and Device Tree Blob(DTB)

Operating System
