Device Configuration

Configuration Signals
The PS of the MPSoC needs to be configured before the FPGA logic can be used. Xilinx Zynq devices need
special boot images to boot from QSPI flash, eMMC flash or SD card. For more information, please refer to
the Zynq Ult MPSoC Technical Reference Manual [19].
Table 37 describes the most important configuration pins and their location on the module connector. These
signals allow the MPSoC to boot from QSPI flash, eMMC flash or SD card, and can be used to program the
QSPI flash from an external master. Please refer to Section 3.12 for details.
