How to install and run Open P4 Studio on Edgecore Wedge100BF-32QS with Ubuntu 20.04?

[stordis-toc]

Requirements and preparation

• Memory CPU, and Disk Space Recommendations
  
  The recommended minimum system sizing is:
  • CPU: x86-64 Memory: 4G
  • Free Disk Space: 60GB
   
• Network Requirements
  
  The installation requires an active Internet connection with access to external sites to install dependencies for third-party packages, including a few common utilities such as Git and Python, and open source dependencies. The overall installation time thus depends both on the system performance, and the speed of the Internet connection.
  
  *Recommended minimum: 10 Mbps Internet connection
   
• sudo Requirement
  
  Commands used in the build process may require sudo access to be executed. We recommend setting up sudo to not require a password. Otherwise the build will pause when a sudo password is needed.

The requirements and preparation for installation is the same as Install Open P4 Studio Software on Edgecore Wedge100BF-32QS.

Prepare your operating system for Open P4 Studio installation

Step 1: Check Current Netplan Configuration

sudo cat /etc/netplan/01-netcfg.yaml

Step 2: Fix Netplan Configuration

Edit the netplan file and ensure proper YAML syntax:

sudo nano /etc/netplan/01-netcfg.yaml

Configure with proper indentation (spaces, not tabs):

network:
 version: 2
 ethernets:
   enp2s0:
     dhcp4: true
   enx020000000002:
     dhcp4: no
     dhcp6: no
     addresses: ['fe80::2/64']
     accept-ra: no

Step 3: Configure BMC Interface Rules

Create new ones for the correct interface:

# Create rule for the correct interface
printf 'KERNEL=="enx020000000002", RUN+="/sbin/ip link set %%k txqueuelen 64"' | sudo tee /etc/udev/rules.d/HCT-enx020000000002-tx_queue_len.rules > /dev/null
# Reload udev rules
sudo udevadm control --reload-rules
sudo udevadm trigger

Step 4: Apply Netplan Configuration

sudo netplan apply

Step 5: Activate BMC Interface

# Bring up the interface
sudo ip link set enx020000000002 up
# Check interface status
ip addr show enx020000000002

Step 6: System Update

sudo apt-get update && sudo apt-get -y upgrade

Step 7: Install Required Packages

sudo apt-get install -y git gdb expect p7zip-full nmap netsniff-ng libvirt-clients language-pack-en

Step 8: Configure System Language

sudo locale-gen en_US.UTF-8
sudo update-locale LANG=en_US.UTF-8

Quick setup Open P4 Studio Software on Ubuntu 20.04.6

Step 1: Download BSP and Open-P4studio files.

In your home directory, e.g. ubuntu, place the downloaded BSP file then unzip it and download open-p4studio

scp bf-reference-bsp-9.13.4.tgz username@host_ip:/home/ubuntu
ls
bf-reference-bsp-9.13.4.tgz
sudo su
git clone https://github.com/p4lang/open-p4studio.git
tar -xf bf-reference-bsp-9.13.4.tgz
cd bf-reference-bsp-9.13.4/packages/
tar -xf bf-platforms-9.13.4.tgz
cp bf-platforms-9.13.4.tgz /home/ubuntu/
mv bf-platforms-9.13.4 /home/ubuntu/open-p4studio/pkgsrc/bf-platforms
cd /home/ubuntu/open-p4studio

Step 2: Run Installation Wizard

Launch the interactive installer:

./install.sh

Configuration selections:

 root@ubuntu:/home/ubuntu/open-p4studio# ./install.sh
 + realpath ./install.sh
 + readonly MY_PATH=/home/ubuntu/open-p4studio/install.sh
 + dirname /home/ubuntu/open-p4studio/install.sh
 + readonly MY_DIR=/home/ubuntu/open-p4studio

Step 3: Configure Environment Variables

Add P4 Studio environment variables to root's bashrc:

sudo su -
cat << 'EOF' >> /root/.bashrc

# P4 Studio Environment Variables
export SDE=/home/ubuntu/open-p4studio
export SDE_INSTALL=${SDE}/install
export BSP=${SDE}/bf-reference-bsp-9.13.4
export BSP_INSTALL=${SDE_INSTALL}
export PATH=${PATH}:${SDE_INSTALL}/bin:${HOME}/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${SDE_INSTALL}/lib

# Auto-load BF modules on login
$SDE_INSTALL/bin/bf_kdrv_mod_load $SDE_INSTALL 2>/dev/null || true
