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 IMG_20211017_153717
  • 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
