Vivado Hardware Server is launched in the shell and will be listening until the shell is closed. All other
Xilinx tools will automatically connect to this instance of the Hardware Server.

Technical Reference Manual (UG1085).
2.2. microSD Boot Mode
The Genesys ZU supports booting from a microSD card inserted into connector J9. The SD supported
version is 3.0. This boot mode suport FAT 16/32 file systems for reading the boot images. Image search
for multi‐boot is supported. For SD boot mode, the boot image file should be at the root of first partition
of the SD card (not inside any directory). The following procedure will allow you to boot the Zynq
UltraScale+ from microSD with a standard Zynq UltraScale+ Boot Image created with the Xilinx tools:
Format the microSD card with a FAT32 file system.
Copy the Zynq UltraScale+ Boot Image created with Xilinx SDK to the microSD card.
Rename the Zynq UltraScale+ Boot Image on the microSD card to BOOT.bin.
Eject the microSD card from your computer and insert it into connector J9 on the Genesys ZU.
Attach a power source to the Genesys ZU.
Place a single jumper on JP3, shorting the pins labeled "SD".
Turn the board on. The board will now boot the image on the microSD card.
For more details about SD boot mode see "SD Boot Mode" section in Zynq UltraScale+ MPSoC Software
Developer Guide (UG1137).
2.3. Quad SPI Boot Mode
The Genesys ZU has an on‐board 256Mbit Quad‐SPI Flash from ISSI that the Zynq UltraScale+ can boot
from. Documentation available from Xilinx describes how to use Xilinx SDK to program a Zynq
UltraScale+ Boot Image into a Flash device attached to the Zynq UltraScale+. Once the Quad SPI Flash
has been loaded with a Zynq UltraScale+ Boot Image, the following steps can be followed to boot from
it:
Attach a power source to the Genesys ZU.
Place a single jumper on JP3, shorting the two center pins (labeled "QSPI").
Turn the board on. The board will now boot the image stored in the Quad SPI flash.
