OpenWRT Raspberry Pi4 • How to compile OpenWRT for Raspberry Pi4 (64bit) with USB NIC support: • No wireless (internal antennae is not very strong) - using old router as standalone AP • Support for USB3 Ethernet Adapter • Note: These are the stpes I used in LinuxMint, but should work for any Debian based OS. • Steps: • Setup the Build Environment • 1. Login into OS after installation. Open Terminal Window and type the following commands: • 2. sudo apt-get update • 3. sudo apt-get install git-core subversion mercurial build-essential libssl-dev libncurses5-dev unzip gawk zlib1g-dev • 4. unset SED • 5. unset GREP_OPTIONS • 6. export GREP_OPTIONS= • 7. export PATH=$PATH:~/openwrt/openwrt/staging_dir/host/bin • 8. export PATH=$PATH:~/openwrt/openwrt/staging_dir/toolchain-mips_34kc_gcc-5.3.0_musl-1.1.16 • 9. Install sublime text 3 | www.sublimetext.com • 10. Install Balena Etcher | https://www.balena.io/etcher • Install OpenWRT Source from GIT: • 1. git clone https://github.com/openwrt/openwrt.git • From OpenWRT Source Tree • 1. cd openwrt • 2. ./scripts/feeds update -a • 3. ./scripts/feeds install -a • To create a custom banner: • 1. Generate ACSII text banner. • 2. Edit openwrt/package/base-files/files/etc and paste your ACSII text • Run OpenWRT Configuration: • 1. make menuconfig • Items we need in OpenWRT Configuration: • 1. Target System = Broadcom BCM27xx • 2. Subtarget = BCM2711 boards 64bit • 3. Target Profile = Raspberry Pi 4b • 4. Target Images = squashfs • 5. Kernel Modules - • -- USB Support = kmod-usb-hid • = kmod-usb-net • = kmod-usb-net-asix • = kmod-usb-net-asix-ax88179 • = kmod-usb2 • = kmod-usb3 • 6. Libraries • -- libssh • -- libssh2 • 7. LUCI - • -- Collections - • = luci • = luci-ssl-openssl • 8. Save • 9. Exit • 10. make (or to use multiple cores) make -jx (where x = cpu cores+1) • • How to burn the image to your card and boot • 1. Download and install Etcher: https://www.balena.io/etcher • 2. Burn the image file from /openwrt/bin/targets/bcm27xx/ • • How to Overclock • 1. Downlaod and install Sublime 3: www.sublimetext.com • 2. Edit config.txt • 3. Add: • [pi4] • over_voltage=6 • arm_freq=2147 • • How to create a new SSH key pair (private/public) • 1. ssh-keygen • 2. pick location to save • 3. enter passphrase (optional) • 4. Using Web Interface, go to the Administration tab • 5. Under Services sub-tab, Enable SSHd in the Secure Shell Section • 6. Paste your public key in the authorized key of the SSHD section that has now expanded. • 7. Save and Apply settings • • How to login and setup the WAN interface: • ref: / lede-openwrt-using-raspberry-pi-as-firewall • 1. Login into the web interface: https://192.168.1.1 • 2. Network - Interfaces - Add new interface • 3. WAN and select eth1 from interface list. • 4. Select DHCP Client as protocol • 5. Select WAN as FW zone in FW setting tab
