![]() ![]() If you do manage to replace all your userland binaries with 64-bit versions, using one of the other ways of setting the kernel might be a better choice as that will ensure you don't try to run 64-bit binaries in 32-bit kernel. ![]() I'm still looking for the official way to install 64-bit python (et. However, once running the kernel in 64-bit (confirmed with uname -m = 'aarch64'), you won't be able to really take advantages of the possible speed improvements (which, contrary to some popular belief, is real) unless you also install 64-bit binaries of the programs that you want to run.įor instance, to check if python is compiled to run on a 64-bit kernel or 32-bit: python -c 'import struct print(8*struct.calcsize("P"))' Explicitly set kernel= to the 64-bit kernel.Delete the 32-bit kernel images (in which case it will "fall back" to 64-bit).There are a couple other "official" ways that are, imho, sub-par. (Just make sure /boot/kernel8.img exists first). Raspberry Pi OS is not affiliated with the Debian project. The "official" way to have your Pi boot in 64-bit mode is to add a line arm_64bit=1 to /boot/config.txt. 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. Currently this is only available on Raspberry Pi 3 or higher (with one exception: Raspberry Pi 2 Model B v1.2). Note, you will need a CPU that is capable of ARMv8 for the 64-bit kernel to boot. Not all applications or libraries work.īy default, Raspbian uses the 32-bit kernel, but all recent versions of Raspbian include a 64-bit version ( kernel8.img). Beta versions are now available that install 64-bit versions of applications. ![]()
