Build instruction

In this section, I will briefly introduce how to make PYNQ SD card Image for ANTSDR. For detail information, please refer to PYNQ SD card.

Pre-conditions:

Host computer: Ubuntu18.04 LTS ( this is the tested version)
petalinux 2022.1 (install path /opt/pkg/petalinux/2022.1)
Vivado/Vitis 2021.1 (This is fine for me to create the e200 Boot.bin, and hdl project)

You should install the required software into the corresponding path .

• Set up the host

cd PYNQ/sdbuild/scripts/
./setup_host.sh

This will take a few minutes to setup the host environment. After it finished, you will the the quem and crosstool-ng folder in /opt .

 wcc@wcc-dev:/opt$ ls -l /opt/
 total 32
 drwxr-xr-x 6 root root 4096 1月   7  2020 crosstool-ng
 drwxr-xr-x 3 wcc  wcc  4096 1月   4  2020 pkg
 drwxr-xr-x 6 root root 4096 1月   7  2020 qemu
 drwxrwxrwx 6 wcc  wcc  4096 1月   7  2020 Xilinx

• Build the SD card Image

source /opt/pkg/petalinux/2022.1/settings.sh 
source /opt/Xilinx/Vivado/2021.1/settings64.sh
source /opt/Xilinx/Vitis/2021.1/settings64.sh 

cd sdbuild
make BOARDS=e200 # if your board is e310, there should be e310

Once PYNQ image is ready, you can find e200's PYNQ image at output folder. Burn that image into a SD Card.

Special Note for E200

The Ethernet of E200 is located at PL side, the default Boot.BIN doesn't contain bitstream, this will cause the ethernet could not be detected at boot time, so we need to package bitstream into the Boot.BIN file. We have a folder e200_boot_gen, you can created the Boot.BIN file using this folder.

cd e200_boot_gen
make sdimg

You can find the BOOT.BIN file at build_sdimg folder. Now you can replace the BOOT.bin file in the boot partition of the SD card with the generated BOOT.BIN file.

Setup PYNQ for AntSDR

You should insert the SD card into antsdr, connect antsdr to the router with a network cable(the antsdr needs to acess to the internet for building libiio from source at first time), connect to the serial port of antsdr and computer with usb, and power on.

From the serial port terminal, you can see the printed information about PYNQ startup.

Once the PYNQ boot up, you can interact with antsdr through serial port.

xilinx@pynq:~$

You need to connect the ethernet cable to a router, the following steps will needs antsdr to have an access to network.

sudo apt update
sudo apt install libxml2 libxml2-dev bison flex cmake git libaio-dev libboost-all-dev libusb-1.0-0-dev libavahi-common-dev libavahi-client-dev

• Build and install libiio from source:

git clone -b v0.24 https://github.com/analogdevicesinc/libiio.git
cd libiio
mkdir build
cd build
cmake .. -DPYTHON_BINDINGS=ON
make 
sudo make install
cd ../..

git clone https://github.com/analogdevicesinc/libad9361-iio.git
cd libad9361-iio
mkdir build
cd build
cmake .. -DPYTHON_BINDINGS=ON
make 
sudo make install
cd ../..

• Install pyadi-iio

pip3 install pylibiio
pip3 install pyadi-iio
sudo pip3 install pylibiio
sudo pip3 install pyadi-iio

FPGA bitstream reload and devicetree overlay

Since reloading the bit file each time can cause the IIO driver to not work properly, it is necessary to dynamically load the drivers related to AD9361 using device tree overlay. This requires the use of device tree plugins. You should build the devicetree overlay at your host computer, inside the project, we have a PYNQ-PRIO folder, this folder will help us build the dtbo file.

wcc@wcc-pc:~/wcc_demo/PYNQ/PYNQ-PRIO$ tree -L 2
.
├── boards
│   ├── e200
│   ├── e310

│   ├── dtc-1.4.4
│   ├── install.sh
│   ├── Makefile

└── setup.py

• Run "Install.sh" script.

cd PYNQ-PRIO/device_tree_overlays
./install.sh

Now we can create our overlay:

make BOARDS=e200

You can find the pl.dtbo file at e200's subfolder.

HDL base project

If you need to develop your own FPGA project, the basic project for E200 is available in the following link, this could be your starting point of your own project.

git clone -b antsdr_fmcomms https://github.com/MicroPhase/hdl.git
source /opt/Xilinx/Vivado/2021.1/settings64.sh 
cd hdl/projects/antsdre200/
make
