The Raspberry Pi 400, announced in November 2020, is quite similar to the Raspberry Pi 4 B models. ![]() More technical details about Raspberry Pi 4 support are available on the RaspberryPi4 page. You can also run regular Debian on your Raspberry Pi's! (keep reading.)Īnnounced in 2019, this system adds a second HDMI port, more memory, true Gigabit Ethernet and USB3. ![]() Questions related to Raspberry Pi OS should be asked on (f.e.) their forums. Raspberry Pi OS is not affiliated with the Debian project. Raspberry Pi OS builds a single image for all of the Raspberry families, so you will get an armhf 32-bit, hard floating-point system, but built for the ARMv6 ISA (with VFP2), unlike Debian's ARMv7 ISA (with VFP3) port. This is, first of all, for historical reasons (booting a mainline Linux kernel was not supported on Raspberries until late 2018), but also because of other non-free components that are shipped as part of Raspberry Pi OS (such as Oracle Java, Wolfram Mathematica, and several games such as a Pi-specific Minecraft version). The most often used distribution across all raspberries is Raspberry Pi OS (originally known as Raspbian), a derivative of Debian. Raspberry Pi OS (formerly Raspbian) and Debian This binary blob is available in the non-free Debian repository, packaged as the raspi-firmware package (or raspi3-firmware until Debian 10). To know more, please read on.Īll Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3, Zero 2 W) boot from their GPU (not from the CPU!), so they require a non-free binary blob to boot. To quickly get a ready-to-use image, visit RaspberryPiImages. QEMU User Emulation for Raspberry Pi Development.Raspberry Pi 1 (A, B, A+, B+, Zero, Zero W).Raspberry Pi OS (formerly Raspbian) and Debian.If you can backup so that you replace such stuff into the new OS then that may indeed be the easier (and probably quicker way to go) - but upgrading in-place can be desirable to continue with a system that the RPi is incorporated in and which it has been locally configured to work for. One point the other existing answers don't seem to have noted about just getting a whole new distribution image and replacing the existing one is that that will also discard anything else that you might have configured/built/installed on the existing installation. apt-get will moan about the new version not being explicitly accepted and requiring you to approve the update with apt-secure - whereas apt (in all the cases I have encounter this on Desktop Linux machines) will accept the change and get on with it. ![]() as mentioned in update problem with apt-get after new install of OS. ![]() Whilst gives some of the details it seems to omit one gotcha that can occur when you have changed the release name in the sources, e.g. One thing to watch out for is that apt-get is no longer the command to use for command line work and instead using apt directly is recommended. I have been away from the RPi scene for a while, but I'd be surprised if you could not do a "distribution" update which involves ensuring the current (major release number) version on your RPi is fully updated before editing the sources to change it to the next one and then updating to that.įor example the later part of details this for upgrading from Stretch to Buster, but the process to go from Buster to Bullseye should be the same except you have to juggle the names used (where "stretch" was referred to, you use "buster" and where "buster" was used you need to have "bullseye").
