![]() If, on the other hand, you see a reference to "armv7" in the output, the system is still 32-bit - you can change it now. Normally this shouldn't be the case, but if you get an indication of "aarch64" as an output, your Pi is already switched. You can now start with the commandįind out if your Pi isn't already running the 64-bit kernel of the Raspberry Pi OS. So far you have only carried out the "normal" maintenance work, which is useful anyway. Optional: Check the current operating mode of the Raspberry Pi for 64-bit This may take a while if you haven't done it for a while. The Pi now carries out all necessary system updates and installs them directly. Next you should update the Pi: First give the commandĪ. ![]() All pricing and availability information on at the time of purchase applies to the purchase of this product. Product prices and availability are correct as of the date/time shown and are subject to change. In this case, you must of course adapt the command accordingly. Log in to the handicraft computer, provided you have not changed your username and password. After booting, you can use a terminal or powershell window as usual ![]() Wire up your Pi and connect it to power if you haven't already done so. Danger: Don't forget to backup! In addition, you only have to do this on running Pi systems: If you reinstall, you can simply download the 64-bit version in the Raspberry Pi Imager choose. It's "easy as 1-2-3" as Michael Jackson used to sing. In short: 64-bit is worth it - and anyone who does not occasionally use the memory card with the system in an older Raspberry Pi should upgrade. In addition, 64-bit on the Raspberry Pi also opens up the possibility of running very memory-intensive applications on (future) Pi boards with more RAM. ![]() Beyond that there are some performance benefits intrinsic to the A64 instruction set: Today, these are most visible in benchmarks, but the assumption is that these will feed through into real-world application performance in the future.A 64-bit system has a number of advantages: the Pi processor, which has long been built in 64-bit technology, is better utilized, and Raspberry Pi boards with 8 gigabytes of RAM can finally be fully utilized, since there are no longer four gigabytes RAM mark the upper limit. "Compatibility is a key concern: Many closed-source applications are only available for arm64, and open-source ones aren't fully optimised for the armhf port. "We've come to realize that there are reasons to choose a 64-bit operating system over a 32-bit one," explains Raspberry Pi's Gordon Hollingworth of the move. Raspberry Pi OS 64-bit, by contrast, is incompatible with older boards: It will run perfectly well on the Raspberry Pi 3, Raspberry Pi 4, and Raspberry Pi Zero 2 ranges, but won't boot on the original Raspberry Pi, Raspberry Pi 2, or Raspberry Pi Zero models. It's a big shift for the company, which had previously focused on providing a single operating system image compatible with every single one of its single-board computer - going all the way back to the original Raspberry Pi Model B and its ARM1176 cores, and even beyond to the first alpha boards ever shipped. Also promised, to follow at a later date: A 64-bit version, to be officially supported and updated alongside the existing 32-bit release. ![]()
