The three boot modes are described in the following sections.
3.1 microSD Boot Mode
The Arty Z7 supports booting from a microSD card inserted into connector J9. The following
procedure will allow you to boot the Zynq from microSD with a standard Zynq Boot Image
created with the Xilinx tools:
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 J9 on the Arty
Z7.
5.
Attach a power source to the Arty Z7 and select it using JP5.
6.
Place a single jumper on JP4, shorting the two top pins (labeled “SD”).
7.
Turn the board on. The board will now boot the image on the microSD card.
3.2 Quad SPI Boot Mode
The Arty Z7 has an onboard 16MB Quad-SPI Flash that the Zynq can boot from.
Documentation available from Xilinx describes how to use Xilinx SDK to program a Zynq
Boot Image into a Flash device attached to the Zynq. Once the Quad SPI 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 Arty Z7 and select it using JP5.
2.
Place a single jumper on JP4, shorting the two center pins (labeled “QSPI”).
3.
Turn the board on. The board will now boot the image stored in the Quad SPI flash.
3.3 JTAG Boot Mode
When placed in JTAG boot mode, the processor will wait until software is loaded by a host
computer using the Xilinx tools. After software has been loaded, it is possible to either let the
software begin executing, or step through it line by line using Xilinx SDK.
