4. Post-Boot and On-Target Development

Once the system has booted on the FPGA board, you can perform initial setup, install packages, and build your applications directly on the target.

First Boot Setup

Ethernet Configuration

If the Ethernet connection doesn’t work out of the box:

1. Check kernel messages for hardware detection:

   dmesg | grep -i -E "eth|phy|macb|gem|mdio"
   

2. If the hardware seems fine, request an IP address via DHCP (replace enx... with your actual interface name, which you can find with ip a):

   sudo udhcpc -i enx000a35001e53 -n -q -f
   

System Updates

1. Set the correct date and time to avoid issues with package management certificates:

   # Example for June 8th, 2025, 2:30 PM
   sudo date 060814302025
   

2. Update the system packages using dnf:

   sudo dnf update
   

Building libcaer on Target

1. Install build dependencies on the Zybo board:

   sudo dnf install libusb-1.0-devel opencv-devel
   

2. Copy the libcaer source code from your host to the target:

   rsync -avz /path/to/libcaer/ petalinux@<TARGET_IP>:/home/petalinux/
   

3. Build and install libcaer on the target:

   cd libcaer
   mkdir build && cd build
   cmake .. -DCMAKE_INSTALL_PREFIX=/usr
   make
   sudo make install
   

Building a Custom DVS Application

Once libcaer is installed, you can compile your application using g++:

g++ -std=c++11 -pedantic -Wall -Wextra -O2 -o dvxplorer dvxplorer.cpp -D_DEFAULT_SOURCE=1 -lcaer
