3 Pre-Programmed Memory
This section describes the factory programmed applications that reside on the Zynq 7Z045 Mini-Module
Plus upon shipment. Other test and reference designs are posted on the Zynq 7Z045 Mini-Module Plus
DRC page under the “Support and Downloads” link.

Both the QSPI and the included micro SD card included with the Zynq 7Z045 Mini-Module Plus board are
pre-programed with applications that allow the user to quickly power on the board and utilize some of the
board peripherals.
3.1
QSPI
– PCI Express Endpoint
The QSPI devices on the Zynq 7Z045 Mini-Module Plus are programmed with the Xilinx PCI
Express 2.0 Endpoint design that is created from CoreGen. This application allows the Zynq 7Z045
Mini-Module Plus system to be enumerated on a PCI Express bus and simple bus transactions be
made.
The Zynq 7Z045 Mini-Module Plus is shipped with the configuration SW5 set to configure from the
QSPI interface. SW5 should be set to
SW5[0:4] = x0010
. The user can install the Zynq 7Z045 Mini-
Module Plus system into a PCI Express slot and power up the system and see the Zynq 7Z045
Mini-Module Plus system enumerated on the PCI Express bus using a PCI Express bus
analyzer/viewer such as PCI Tree.
NOTE
: The Mini-Module Plus Baseboard does not get power from the PCI Express slot. The
external power supply shipped with the baseboard must be used to power the Zynq 7Z045 Mini-
Module Plus system.
3.2
Micro SD Card
– Linux
The supplied micro SD card shipped with the Zynq 7Z045 Mini-Module Plus is pre-programmed
with a Linux image that will boot upon power-up when the configuration switch SW5 is set to the
proper mode. To configure from the micro SD card and boot Linux set
SW5[0:4] = x011x
.
Prior to power-on the user will need to attach a USB cable between the Zynq 7Z045 Mini-Module
Plus USB UART connector J4 and a PC or laptop. Open a terminal session and set it for the correct
COM port (shown in the device manager as CP210x) with the following settings: 115200-8-N-1.
Once the terminal shell is open turn on power to the system and the user will see Linux booting on
the terminal screen. After boot is complete a Linux command line will be present and commands
can be entered.
NOTE
: The PC or laptop will require the Silicon Labs CP210x driver be installed in order to use the
USB UART interface. These drivers can be found at the Silicon Labs website or on the Avnet Zynq
7Z045 Mini-
Module Plus DRC site under the “Support and Downloads” link.
