Also, many of the binary packages are themselves quite large (for example, the current libreoffice binary package is >100MiB) and so time-consuming to download (unless you have a very fast Internet connection). See these notes for further details. 3 model B and 3 model B+ single board computers (SBC). Of course, take the normal precautions when running an internet-exposed server in this manner: for example, set up an appropriate firewall, consider running the server process under firejail, modify the shipped-default passwords, and keep your system up-to-date by (manually) running genup, from time to time. When it has completed, go into the newly created linux directory, and set up the baseline configuration. As such, updating (via genup, for example, or an old-school eix-sync && emerge -uDUav --with-bdeps=y @world) is much less onerous than before, and so has been automated on the image (via the app-portage/weekly-genup package, which installs a script in /etc/cron.weekly). In the instructions below I'm going to assume you're using Linux. Neither the Pi3 nor Pi4 is shipped with the ARMv8 hardware crypto extensions enabled, unfortunately. Each kernel has a distinct release name, and so a separate module set in /lib/modules/. gcc-6.x allows the use of -march=native but that will prevent the use of distcc. This issue should resolve itself after your next login, however. It is a feature of USB storage that trim is disabled by default. a PCI-based reader); in any case, the actual path will depend on your system - you can use the lsblk tool to help you). Alternatively, for those who prefer the Raspberry Pi NOOBS installer GUI, both images are now available for installation using PINN (called gentoo64 and gentoo64lite there). You may also find it useful to keep an eye on this project's (sticky) thread in the 'Gentoo on ARM' forum at gentoo.org, as I occasionally post information about this project there. Choose either the full (recommended for most users) or 'lite' (command-line only) variant, then follow the appropriate instructions below (full or lite). The restriction does not apply to the RPi4. For simplicity, the image uses a single ext4 root partition (includes /home), which by default will be auto-resized to fill all remaining free space on the microSD card on first boot. You should now find that you can switch layouts (if you have specified more than one) either by clicking on the top panel-bar keyboard plugin (the one next to the Demo User text on the far right) or by pressing the hotkey (by default, this is Windows KeySpace). And finally, as of 1.6.0, rpi-5.4.y kernels are supported, the FOSS Jitsi videoconferencing server is bundled, and elogind is used in place of consolekit. Contact Curious users need to be familiar with the use of a cross toolchain or have access to another armv8a system to build a 64-bit kernel for the Pi 4. Also, to allow large packages (such as gcc) to be built from source without running out of memory on smaller systems, a 1 GiB swapfile has been set up at /var/cache/swap/swap1, and on boot this will be auto-resized if necessary, if space becomes tight (by this service). For further details, please see my wiki tutorial here. Changes made to the /boot/config.txt file using this application are subject to ratification on reboot; if you do not explicitly accept them before a short time limit expires, an automatic reboot under the prior, 'last known good' config is performed. RealVNC only provides a 32bit app for Raspberry Pi OS (32bit) and not a 64bit native application, at least for now. The file can be edited on any PC (since the first partition is formatted FAT) and you need to make any changes prior to first boot. There are 3 release channels of firmware updates: To configure which release channel you'd like the updater service to follow, edit /etc/conf.d/rpi-eeprom-update. As of v1.5.0 of the image, these tools also work on an RPi4.Given an appropriately patched ffmpeg (which is present in >=v1.4.0 of the image), exploiting these features from the command line is very simple - see the example 'recipes' (which work for both the RPi3 and RPi4) in this project's open wiki. And, there is no 3GiB 'memory ceiling' anymore: if you are fortunate enough to own a 8GiB Pi4, all 8GiB of that RAM is usable. Then you can try installing it, using emerge: Once this completes, you can use your new package! https://wiki.gentoo.org/index.php?title=Raspberry_Pi4_64_Bit_Install&oldid=911371. Begin with your RPi4 (or RPi3) powered off. If you wish to share files on a network with Windows boxes, please note that net-fs/samba is bundled as of version 1.2.2 of the image. This is managed by the sys-apps/rpi3-ondemand-cpufreq package (see below). See the guide at sakaki-/gentoo-on-rpi-64bit guide to get started with gentoo, or alternatively use sakaki-/bcm2711-kernel-bis if you want to use Raspberry Pi OS. For further details, please see my wiki tutorial here. As mentioned, it is wise to use a spare microSD card as your target, keeping your existing Raspbian microSD card in a safe place; that way, you can easily reboot back into your existing Raspbian system, simply by swapping back to your old card. The project's Gentoo binhost at https://isshoni.org/pi64pie has been reconfigured to perform a weekly update and autobuild of all installed (userspace) packages on the image, allowing your RPi3/4 to perform fast updates via the resulting binary packages where possible, only falling back to local source-based compilation when necessary (using this facility is optional, of course, just like the binary kernel package). PermitRootLogin yes has explicitly been set in /etc/ssh/sshd_config, and sshd is present in the default runlevel. RealVNC only provides a 32bit app for Raspberry Pi OS (32bit) and not a 64bit native application, at least for now. As of version 1.2.2 of the image, a startup service (rpi3-safecompositor) is used to turn off display compositing if a high pixel clock is detected (> 1.2175MHz, currently), and an RPi3 is in use. Modify /etc/sudoers via visudo to change this, if desired (the relevant line is %wheel ALL=(ALL) NOPASSWD: ALL). It should exit cleanly when done - if you get a message saying 'No space left on device', then your card is too small for the image, and you should try again with a larger capacity one. An sysctl.d rule (35-low-memory-cache-settings.conf) is used to modify the kernel cache settings slightly, for better performance in a memory constrained environment, per these notes. While you could in principle also use an RPi4 in the Pi-Top chassis, you'd need an adaptor for the microHDMI and power connectors, and you may also find the unit draws more power than the Pi-Top circuitry can supply, so this approach is not recommended. You should also be able to change the screen backlight brightness using the keyboard buttons, see the remaining battery charge in the top panel, and find that the when you shut down your system, the hub powers off your Pi-Top properly. Feel free to modify this configuration as desired (for example, you can significantly improve performance under load by setting up a dedicated swap device on a separate bus from the system's rootfs; for details, please see this short tutorial). If you like, you can run a GUI, even a full desktop, on your guest OS, as further detailed here. In order to install the kernel on a Pi 400, install the relative device tree. If you are using a Pi-Top chassis, have emerged rpi-64bit-meta with the pitop USE flag set, and have one or more pi-topSPEAKER units plugged in, the HDMI audio stream will automatically play though these. The binhost also provides a (weekly-gated) rsync mirror (rsync://isshoni.org/gentoo-portage-pi64-gem) for the main gentoo repo (fully compatible with Gentoo's official gemato signed hash verification), used to keep your RPi3/4's "visible" ebuild tree in lockstep with the binary package versions available on the isshoni.org binhost (incidentally, the gentoo repo on isshoni.org itself is maintained against upstream using webrsync-gpg). Switching back to the "-bis" binary kernel package pair, should you subsequently wish to do so, is just as straightforward; simply become root again and issue: Reboot immediately the above command completes. If you need to install a particular package that isn't currently in the Gentoo tree, note that it is possible to install binary packages from Raspbian (or other 32-bit repos) on your 64-bit system. Put all your data from any source in one place, so all your teams can see everything in context, collaborate more easily, and resolve issues faster. Used by my bootable gentoo-on-rpi-64bit image. Tip: if you'd like to set up a persistent dual-monitor setup on an RPi4, please see my short tutorial on this project's open wiki here (this also contains useful hints for setting up a single display). Also, note that by default (via the with-matching-boot-fw USE flag) installing a particular sys-kernel/bcm{rpi3,2711}-kernel<-bis>-bin version will also cause the version of sys-boot/rpi3-64bit-firmware (see above) current at the time the kernel was released, to be installed (to /boot). Please refer to the official Programmer’s Guide for ARMv8-A for more details. NB: I can make no guarantees about the future availability of the weekly autobuilds on isshoni.org, nor the autoupdated binary kernel packages (on GitHub). You may need to reformat (with the drive manufacturer's utility) them to enable 512 byte emulation. beta - New or experimental features are tested here first. On the RPi4, you can easily try overclocking your system, without voiding your warranty. Raspberry Pi boards are functional single-board computers (SBCs) capable of serving as a foundation for a smattering of projects. Build and install the kernel, device tree, and kernel modules an described in Raspberry Pi 3 article. You should then see the 'rainbow square' startup sequence once more, and then the system will resize its root filesystem, to fill the newly enlarged partition. via ssh (although, for completeness, it is possible to ssh in via the Ethernet interface (which has a DHCP client running), if you can determine the allocated IP address, for example from your router, or via nmap). Bluetooth is operational on this image, but since, by default, the Raspberry Pi 3 uses the hardware UART / ttyAMA0 to communicate with the Bluetooth adaptor, the standard serial console does not work and has been disabled (see /etc/inittab and /boot/cmdline.txt). the screen lock comes on; you can also do sudo su --login root to get a root prompt at the terminal, without requiring a password). The autoexpand_root_partition.start script has been migrated into an OpenRC boot service, provided by sys-apps/rpi3-init-scripts. (For those interested, OpenMAX-IL is not yet supported in 64-bit.). To search for available packages, you can use the (pre-installed) eix tool. Phoronix Member. For this naming format, the trailing digit is part of the drive name (partitions are labelled as e.g. (Warnings that the key is "not certified with a trusted signature" are normal and may be ignored.). Hint: if you wish to use your RPi3/4 in a headless context, as of v1.5.2 of the image you can edit the file startup.sh on the first partition, to e.g. The whole process (from first power on to graphical desktop) should take less than three minutes or so (on subsequent reboots, the resizing process will not run, so startup will be a lot faster). Bootable 64-bit Gentoo image for the Raspberry Pi 4 Model B, and Pi 3 B and B+, with Linux 5.4, OpenRC, Xfce4, VC4/V3D, camera & h/w codec support, profile 17.0, weekly-autobuild binhost, 30 Oct 2020: sadly, due to legal obligations arising from a recent change in my 'real world' job, I must announce I am standing down as maintainer of this project with immediate effect. It won't affect your ability to build other packages on your RPi3/4. Power Over Ethernet requires a .dto file to be loaded as well as kernel support. You've got this far through the README - I'm impressed ^-^. You can view this profile (provided via the genpi64 ebuild repository) here. You signed in with another tab or window. It is a similar story with the Mozilla Thunderbird mail client. If you are using a Windows or Mac box, or prefer to use a GUI tool in Linux, I recommend you download your preferred image via your web browser using the links above, and then check out either of the the free, open-source, cross-platform tools Etcher or usbimager to write it to microSD card. As of version 1.3.1 of the image, and as noted earlier, a simple tool, pyconfig_gen has been provided, for easy (GUI-based) update of (a subset of the features contained in) the /boot/config.txt file on the RPi3. Firmware (/etc/firmware/BCM43430A1.hcd) for the RPi3/4's integrated Bluetooth transceiver is provided by sys-firmware/bcm4340a1-firmware (adapted from the Arch Linux pi-bluetooth package). The microSD interface supports the trim command: If you have a suitable microSD card, consider adding fstrim to a weekly or monthly cron job. Alternatively, to install source packages with highly resource-intensive build profiles (such as dev-lang/rust), you can temporarily mount the image within a binfmt_misc QEMU user-mode chroot on your Linux PC, and perform the emerge there. If you wish to use the camera, and hardware video codecs, also ensure that the below lines read as follows (if not, this step may be omitted): Leave the rest of the file as-is. The Ethernet interface is initially configured as a DHCP client, but obviously you can modify this as needed. This is for initial convenience only - feel free to adopt a more restrictive configuration. In fact, you may be just the sort of person to help get arm64 into a more stable state in the main Gentoo tree... To that end, if you have managed to get additional packages (not included in the original pre-installed set) working reliably on your gentoo-on-rpi-64bit system, please feel free to submit PRs for the relevant profile elements of the genpi64 overlay (for example, package.accept_keywords, package.bashrc and package.use entries). A program for improving image files from digital cameras (HDR etc). Now bundled with the image for convenience, for those who would like to use their RPi3 as an external programmer to reflash the firmware on their PC. Note that you are likely to require active cooling for your RPi4 when overclocked, and it is always possible (although unlikely) that your device may fail to boot at the faster settings (if it does, simply edit the file config.txt on the first partition of the microSD card, comment out the arm_freq and gpu_freq settings, and try again). You can easily install (and run) 32-bit Raspbian apps on your 64-bit Gentoo system if you like (using apt-get from a chroot), since ARMv8 supports mixed-mode userland. If you wish to add Bluetooth peripherals (e.g., a wireless mouse and/or keyboard) to your RPi, please see below. A lot of packages have been * ~* keyworded to get the system provided here to build... but hey, if you like Gentoo, little things like that aren't likely to put you off ^-^. USB (and take care to unmount your existing /boot directory before removing the original microSD card), or are booted directly from USB. Work fast with our official CLI. It is particularly intended to allow e.g. Cross compile and install the kernel. Issue amixer -c 0 cset numid=3 2 to turn HDMI audio output on again (muting the headphones). RealVNC Server on UBUNTU 20.10 (ARM64) on Raspberry Pi 4. The image uses the RPi3/4's hardware random number generator to feed /dev/random (via sys-apps/rng-tools); see these notes for further details. One other thing to note, the Raspberry pi currently only supports booting from usb mass storage devices (including external hard drives) that have a 512 byte logical sector size. To use, edit the startup.sh script (on e.g. NB: this repository has been renamed, from rpi3-overlay to genpi64-overlay, to reflect its applicability to the new Pi4. As of v1.3.1 of this image, you can also use the bundled GUI tool (shown in the screenshot above) to modify (some of) these settings. If you would rather not use auto-updating, simply edit the file /etc/portage/package.use/rpi-64bit-meta so it reads (the relevant line is the last one): Then re-emerge the meta package, which will remove the cron entry (NB: doing it this way ensures the entry stays removed, even if you later manually update your system): Of course, you can always use genup directly (as root) to update your system at any time. The above xzcat to the microSD card will take some time, due to the decompression (it takes between 5 and 25 minutes on my machine, depending on the microSD card used).
