We need to add our settings to the dnsmasq config file, which is where most of the magic happens. This isn’t a problem on a home network where you trust all the computers, but don’t run this setup exposed to the public internet.Įcho "/nfs/raspi1 *(rw,sync,no_subtree_check,no_root_squash)" | sudo tee -a /etc/exports Do note that we’re not setting up a particularly secure NFS service.
Setting up the NFS share is as easy as adding a line to /etc/exports and starting the services.
Sudo sed -i /UUID/d /nfs/raspi1/etc/fstabĮcho "console=serial0,115200 console=tty root=/dev/nfs nfsroot=192.168.2.209:/nfs/raspi1,vers=3 rw ip=dhcp rootwait elevator=deadline" | sudo tee /nfs/raspi1/boot/cmdline.txt Be sure to replace nfsroot IP address with the IP of the Debian machine serving as the PXE server. We’ll create a file in the boot folder to enable SSH, modify the Pi’s fstab so it won’t look for filesystems on the SD card, and finally replace the boot command in cmdline.txt.

The advantage here is that the kernel and rest of the boot code can be updated using apt.Įcho "/nfs/raspi1/boot /tftpboot/0c4c21e5 none defaults,bind 0 0" | sudo tee -a /etc/fstab We’re also using a bind mount so the /boot folder is accessible as part of the tftp service, as well as being mounted as part of the NFS share.

You’ll want to replace each “0c4c21e5” below with the serial number you found earlier. The first place a Pi attempts to PXE boot from is a folder named the last 8 characters of that serial number. Remember that serial number from earlier? Here’s where it comes into play.

Sudo apt-get install unzip kpartx dnsmasq nfs-kernel-server The Raspbian image we’re using does need two files manually updated, which is why we’re deleting and re-downloading start4.elf and fixup4.dat The following simply builds the Pi’s filesystem as an NFS share. These instructions should apply for a Raspbian server as well. This time, let’s use Debian, and see if we can get PXE working on an existing home network. Last time we set up a PXE server, we used Centos and a dedicated network. That’s all the setup needed for the Pi itself. Take note of the last 8 characters of that code, as we’ll use it later. We’re interested in the entry for the Pi’s serial number. That last command should output some information on the Pi itself. Rpi-eeprom-config -out pieeprom-netboot.bin -config bootconf.txt pieeprom-.bin Rpi-eeprom-config pieeprom-.bin > bootconf.txt Once the Pi 4 is booted off your Raspbian SD card, we can do the following to get the firmware updated: We have to grab that firmware, change the boot order configuration, and then flash it to the onboard chip. Bootloader UpdateĪt the time of writing, the eeprom firmware that supports PXE boot is still in beta. This article draws from a pair of official Pi network boot guides. From there, we turn to the PXE server to build the remote filesystem and set up the NFS and dnsmasq services. This means installing Raspbian to an SD card and booting the Pi off of it at least once. To boot a Raspberry Pi 4 using PXE, there are a few steps required, starting with updating that bootloader firmware. Need to start over with a fresh Raspbian image? Easy, just rebuild it on the PXE server and reboot the Pi remotely.Ĭonvinced PXE is for you? Let’s get started! There are few things worse than dragging a ladder out to access a Pi that’s cooked its SD card, not to mention the possibility that you firewalled yourself out of it. On the other hand, if you’re doing a permanent or semi-permanent install of a Pi, PXE is absolutely a winner.

And finally, this isn’t a portable option - you are tethered to that network cable while running, and tethered to your network to boot at all. PXE does require an Ethernet cable WiFi is not enough, so you have that restriction to contend with. What are the downsides, I hear you ask? You might see slower speeds going across the network compared to a high quality SD card, particularly with the Pi 4 and its improved SD card slot. Just recently a beta version of that bootloader was released that supports PXE - booting up over the network - which has become a must-have for those of us who have had consistently bad experiences with root filesystems on SD cards. But there’s more! The Pi 4 sports a very useful new feature, the flashable bootloader. We’ve talked about PXE booting the Raspberry Pi 3B+, and then looked at the Raspberry Pi 4 as a desktop replacement.
