Project developers Raspberry PI reported about the beginning of the formation of 64-bit assemblies distribution Raspberry PI OS (raspbian) based on the Debian 11 batch database and optimized Raspberry PI boards. Until now, the distribution has only 32-bit assemblies unified for all boards. From now on for processors based on Armv8-A architecture, such as Raspberry Pi Zero 2 (SOC BCM2710 with CPU Cortex-A53), Raspberry PI 3 (SOC BCM2710 with CPU Cortex-A53) and Raspberry PI 4 (SOC BCM2711 with CPU Cortex -A72) began to form separate 64-bit assemblies .
For old 32-bit Raspberry PI 1 boards with CPU ARM1176, an ARM6HF assembly is supplied, and for newer 32-bit Raspberry PI 2 and Raspberry PI Zero boards with the Cortex-A7 processor, a separate ArmHF assembly has been prepared. At the same time, all three proposed assemblies are compatible with boards from above-down, for example, an ARM6HF assembly can be used instead of assemblies ARMHF and ARM64, and the ArmHF assembly instead of assembling ARM64.
