The three boot modes are described in the following sections.

3.1

microSD Boot Mode

The ZYBO supports booting from a microSD card inserted into connector J4. The following procedure will allow you
to boot the Zynq from microSD:

1) Format the microSD card with a FAT32 file system.
2) Copy the Zynq Boot Image created with Xilinx SDK to the microSD card.
3) Rename the Zynq Boot Image on the microSD card to BOOT.bin.
4) Eject the microSD card from your computer and insert it into connector J4 on the ZYBO.
5) Attach a power source to the ZYBO and select it using JP7.
6) Place a single jumper on JP5, shorting the two leftmost pins (labeled “SD”).
7) Turn the board on. The board will now boot the image on the microSD card.

3.2

QSPI Boot Mode

The ZYBO has an onboard 128-Mbit Quad-SPI (QSPI) serial Flash that the Zynq can boot from. The ZYBO Base
System Design includes a tutorial for how to configure the QSPI Flash with a Zynq Boot Image using the iMPACT
tool included with Xilinx ISE and Vivado. Once the QSPI Flash has been loaded with a Zynq Boot Image, the
following steps can be followed to boot from it:

1) Attach a power source to the ZYBO and select it using JP7.
2) Place a single jumper on JP5, shorting the two center pins (labeled “QSPI”).
3) Turn the board on. The board will now boot the image stored in the QSPI flash.

The ZYBO ships with a demonstration application pre-loaded into QSPI. For information on this image and how to
restore it if erased, download the Factory Loaded Demo project from the ZYBO page at
