With custom Tomato-based firmware to using my own hardware with OPNsense. One change I had to make is that I’ve switched from using a consumer grade router Pi that doesn’t assume you’re using another Raspberry Pi as a TFTP server. Once netbooting is enabled, the remainder of this guide should work just fine.Īs far as I can find, this is still the only guide to netbooting a Raspberry Using the process described here will be migrated to the updated bootloader. If you update your bootloader via apt, then any configuration changes made The eeprom, in order to prevent it from disabling the netboot setting, but

Some other guides I found suggest that you disable the automatic update for Which unfortunately doesn’t even try to use netbooting. The default option (as of the firmware) is 0x41,

The 0x412 option will look for a TFTP server to boot from via DHCP, then fallīack to the SD card, and then fall back to booting from USB. Sudo rpi-eeprom-update -d -f new-pieeprom-.bin Rpi-eeprom-config -out new-pieeprom-.bin -config nfig pieeprom-.bin # open nfig in your editor of choice and change BOOT_ORDER to 0x412 Then run the following to enable boot from a TFTP server: cd ~Ĭp /lib/firmware/raspberrypi/bootloader/stable/pieeprom-.bin. Several steps are needed: make sure you’re on the latest (>= )įirmware. Updates via USB or NFS, not just the SD card.) This means that the Raspberry Pi folks now support doing firmware ( SELF_UPDATE could previously be enabled, but it’s finally To a new version, which just now, as of this month, arguably has full supportįor netbooting. I managed to get it working just long enough to update the firmware Which also meant remembering to sync that partition with the NFS /boot folderĮven though the SD card wasn’t even mounted 99% of the time,Īpparently the heat of being connected to a Pi was enough to eventually fry I did manage to work out how to get basicįunctionality, but I still had to keep the /boot partition on the SD card, Unfortunately, The Pi 4 was released without

I originally wrote this guide in 2018, and then I got a Raspberry Pi 4 the same
