[PYTHON] Build a PYNQ environment on Ultra96 V2 and log in to Jupyter Notebook

Introduction

Try to hardware the logic with Ultra96 v2. First, create a PYNQ environment on Ultra V2 and access it with SSH and Jupyter Notebook.

First, an overview of the Xilinx processor. -> Xilinx Product Information

Getting started just uses the CPU and doesn't seem to do anything like FPGA. .. When I investigated the method, hoping that FPGA could be used, it seems that there are the following methods.

• PYNQ (Python for Zynq) It can be converted to Python (Jupyter Notebook) hardware. It seems that you do not have to connect with JTAG, which is a simple impression.

• Vivado You can design the hardware with a fresh feeling. It seems to be for hardware engineers.

• Vitis（SDSoC） Arbitrary processing can be made into hardware with C / C ++. It may be easy. Tutorials

Try PYNQ.

Try

download

Open the PYNQ --boards info page.

Download Avnet Ultra96-V2: v2.5 PYNQ image (1,790,291,697 bytes) from Community boards. The download is very slow. I read the documents while I was waiting.

When unfolded, it looks like this.

$ unzip ultra96v2_v2.5.zip
$ ls -l ultra96*
-rw-r--r--1 root root 6604447744 October 12 17:38 ultra96v2_v2.5.img
-rw-r--r--1 root root 1790291697 December 22 21:54 ultra96v2_v2.5.zip

Installation

--Write to SD card

$ sudo dd if=ultra96v2_v2.5.img of=/dev/sdc bs=1MB
6604+1 record input
6604+1 record output
6604447744 bytes (6.6 GB, 6.2 GiB) copied, 502.998 s, 13.1 MB/s

Insert and remove the SD card and mount the SD card. The mount destination is going to be / media / user / root /.

--WiFi settings

$ wpa_passphrase your_ssid
passphrase
network={
  ssid="your_ssid"
  # psk="passphrase"
  psk=0123456789abcdef0123456789abcdef0123456789abcdef
}
$ sudo vi /media/user/root/etc/wpa_supplicant.conf
network={
  ssid="your_ssid"	
  psk=0123456789abcdef0123456789abcdef0123456789abcdef
}
$ sudo vi /media/user/root/etc/network/interfaces.d/wlan0
auto wlan0 # <--Added to the first line
iface wlan0 inet dhcp
    wireless_mode managed
    wireless_essid any
    wpa-driver wext
    wpa-conf /etc/wpa_supplicant.conf

• Start-up

Insert the SD card and turn on the power switch (SW4).

--Login

Check the DHCP server log to see the IP address of the unfamiliar MAC address. Ours was "F8: F0: 05: xx: xx: xx".

$ ssh xilinx@<ip address>

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

xilinx@pynq:~$ 

Use

--Access Jupyter Notebook

Access the following with your browser.

 http://<ip address>/

--Authentication

Enter xilinx in the password field to log in.

--Sample code

Run and read the sample code.

Summary

You have successfully accessed your Jupyter Notebook! There was no problem with a 16 GB SD card, but it seems that it did not burn well with a 32 GB SD card.
