Install 32-bit BOINC on a 64-bit Raspberry Pi.

Why would you do this?

• Projects like UNIVERSE@HOME have no aarch64 Tasks.
• A Raspberry Pi 3b can´t run ROSETTA@HOME because it doesn’t have enough ram.
• DietPi, a popular OS for the Raspberry Pi, uses 64Bit.

Requirements

• 64-bit Raspberry Pi e.g. DietPi

Type:

uname -a

the output should contain the following: aarch64 if there is armhf in the output then you can skip to the Install section. Example output: Linux raspberrypi-1 5.10.103-v8+ #1530 SMP PREEMPT Tue Mar 8 13:06:35 GMT 2022 aarch64 GNU/Linux

Architecture

First, we need to add the 32-bit Architecture to our system with the following command:

sudo dpkg --add-architecture armhf

Now you need to update the package list:

sudo apt update

Remove 64-bit Boinc

To remove the 64-bit version of the Boinc-Client type:

sudo apt remove boinc-client -y

Install 32-bit Boinc

If the output of uname -a is armhf then type:

sudo apt install boinc-client

To install the 32-bit version of the Boinc-Client type:

sudo apt install boinc-client:armhf -y
