PYNQ on Zynq Board (zc702)

Directly use the image for running pynq on zc702:

• Get the Image file from Here
• Untar ZC702-2.6.0.tar.xz
• flash the image to sd card using balena etcher or dd
  sudo dd bs=1M if=<image-name>.img of=/dev/<sdcard>
• Insert the SDCARD into the board
• ON ZC702 keep SW16 boot config switch position: 00110
• You can login to the board accessing the serial port

Issues:

• Solve the jupyter access issue.
  • There are two ways for network connection:
    1. Connect board to common router
    2. Connect board ethernet port directly to PC
  • More Info Here
  • I'm using the first option:
    1. First check whether the network port running on board using ping 8.8.8.8
    2. Then run ifconfig and find out the address of eth0 inet.
    3. On host computer http://<etho0-address>:9090
    4. Ensure port 9090 is not blocked by your router/isp.
    5. Login with password xilinx
• PYNQ-DPU port on zc702
  • Xilinx has a DPU library, it is directly supported to pynq boards via pynq-dpu repo and vitis AI.
  • We will need to port it for ZC702.
  • Reference TRD: Zynq-7000-DPU-TRD
• Figure out the way to include FPGA bit file on the board

Build the image with customized conf file:

• create a test_repo/ZC702 folder inside <pynq>/sdbuild
• The test_repo/ZC702 should contain the ZC702 BSP file which can be downloaded from the xilinx site.
• source the following things if not done already:

export PATH="/opt/crosstool-ng/bin:/opt/qemu/bin:$PATH"
source <path-to-vivado>/Vivado/2018.3/settings64.sh
source <path-to-sdk>/SDK/2018.3/settings64.sh
source <path-to-petalinux>/petalinux-v2018.3-final/settings.sh
petalinux-util --webtalk off

• Create a file called ZC702.spec inside test_repo/ZC702 and edit according to the build need. Following the file that I used for the img present in the repo:

ARCH_ZC702 = arm
BSP_ZC702 = <bsp-name>.bsp
STAGE4_PACKAGES_ZC702 = ethernet

• To build our more customised SD card image while still using the pre-built we can run $ make BOARDDIR=test_repo PREBUILT=<recent-arm-image>.img nocheck_images
