Fix Home Assistant / HAOS Raspberry Pi USB/SSD Boot Freeze

Home Assistant / HAOS

There are few things I dislike more in this world than getting questions on my setup guides that I don’t know the answer to, but thanks to an investigation by Bill Schatzow we can strike one of those issues off the list!

We’ve had a few comments of people who have encountered this issue over the years. Given that at best only 1% of people who visit the site leave a comment I think it’s safe to say that this issue has plagued thousands of people over the past 10-12 months.

Let’s take a look!

PCIe 1x NVMe on Raspberry Pi?! Compute Module 4 Guide

CableCC Vertical Adapter in Compute Module 4 IO Board

I recently covered all the pieces you need for a complete setup to work with the Raspberry Pi Compute Module 4. Today I want to cover the whole reason I wanted to investigate the Compute Module 4: The PCI express capabilities!

In this guide I’ll cover a couple of 1x PCIe to NVMe adapters I picked up to try doing this with as well as full configuration and setup instructions. Let us begin!

Full Compute Module 4 (Raspberry Pi) Setup / Imaging Guide

Raspberry Pi Compute Module 4 mounted in IO Board

The Raspberry Pi Compute Module 4 is primarily meant for embedded projects and didn’t catch my interest at first. That was until people started absolutely smashing previous records on my Pi storage benchmarking site pibenchmarks.com.

Upon further investigation it turns out that people are breaking these records using the Compute Module 4 since it allows running a NVMe drive through PCI express instead of having to use a USB adapter (the current bottleneck in other Pis).

Wanting to investigate these new capabilities for myself I got a hold of some gear and wanted to write a setup and configuration guide on everything you need for a full CM4 (Compute Module 4) setup and how to get it imaged and configured. Let’s get started!

Fixing Storage Adapters for Raspberry Pi via Firmware Updates

StarTech USB312SAT3CB

I’ve covered how to get the right type of storage adapter for your Raspberry Pi for years on this site and cataloged storage adapters that both work and don’t work with the Raspberry Pi. Over the years we’ve learned that many of these adapters can be “fixed” with a firmware update to work with the Raspberry Pi.

In this article I’ll put together an evolving list of firmware adapters that can be fixed with these updates from my own experience as well as comments people have left over the years!

Minecraft 1.17 Caves and Cliffs Paper Server Update Available

Minecraft 1.17 - Caves and Cliffs Update

The 1.17 Caves and Cliffs Part 1 version of Minecraft came out for vanilla very recently but until now the Paper Minecraft server was not available for it. This means that my Raspberry Pi Minecraft script was unable to run this version until now.

Today I checked https://papermc.io/api/v1/paper and sure enough 1.17 was finally in the version list so I updated the Raspberry Pi Minecraft server scripts and they are now available! Raspberry Pi not required, the script will work on most versions of Linux that have apt available.

Upgrade Java Past apt’s OpenJDK 11 on Raspberry Pi OS

OpenJDK 16 on Raspberry Pi OS

The OpenJDK 11 version that comes in Raspberry Pi OS’s apt repositories is ancient. It’s so old that recently people using my Minecraft Java Server for Raspberry Pi script have started getting a warning that Minecraft 1.17 will *not* support anything below OpenJDK 16.

In this article I’m going to share a sneaky trick to update your Java to a newer version than is available in apt using snapd. Let’s begin!

UPS Backup Battery for Raspberry Pi? PiSugar Solderless Setup

PiSugar - Top with LED Battery Indicator

I’ve had the original 900 mAh PiSugar UPS backup battery for the Raspberry Pi Zero for several years now and it’s an absolute game changer. With the wireless capabilities of the Raspberry Pi you have a completely portable and networked computer available that is extremely tiny. It’s much more capable than hooking it up to a power brick and is actually designed for the Raspberry Pi!

In this article I’ll cover how to set up a full UPS battery backup with several hours of available power using the the PiSugar as well as the PiSugar 2 and some of the shortcomings in the first version the 2nd revision fixes. Let’s get started!

Where to get the 64 bit Raspberry Pi OS image for Pi 4 / 400

Pi 64bit OS - Forum Post

Last year a official 64 bit version of Raspberry Pi OS was released. There have been 3 versions of the image released with the latest one just having came out April 9th 2021.

It can be a little tricky to find and I’ve been asked in the comments here before on the site where to find it so I figured it was time to write a quick guide!

Raspberry Pi 400 Overclocking / NVMe SSD Setup Guide

Raspberry Pi 400 Setup w/ NVMe SSD

The Raspberry Pi 400 is the first offering from the Raspberry Pi lineup that is meant to approach desktop level performance. The official raspberrypi.org site lists the Pi 400 kit as the “Raspberry Pi 400 Personal Computer Kit“. It comes in the very interesting form factor of a keyboard with all the ports right in the back!

Although the performance on stock clock speeds and with a SD card was really great, especially for a Raspberry Pi, I would not call it desktop class performance. Fortunately we *can* make it desktop class performance with a few tweaks! This guide will show how to overclock the Pi 400 as well as set it up with a NVMe SSD to get the maximum possible performance we can out of it!

Raspberry Pi: Reclaim ~1% CPU Usage when SSD/USB Booting

SSD Ubuntu 'Top' - Fixed

Native support for USB mass storage device booting has made it’s way to all of the Raspberry Pi 4’s firmware release channels! With that exciting development an old issue from the Pi 3 and earlier USB booting days has manifested itself once again in the form of a constant 1-2% CPU draw even with nothing running.

This guide will show you an easy config.txt parameter to eliminate this problem and optimize your mass storage boot setups!

2020’s Fastest Raspberry Pi 4 Storage SD / SSD Benchmarks

Raspberry Pi Storage Benchmark 2020

We’ve now received over 20,000 benchmarks at https://pibenchmarks.com/! These are submitted by regular people from all over the world.

In celebration of that milestone as well as the launch of the 8GB Raspberry Pi 4 take a closer look at which device you should choose for your Raspberry Pi 4 as determined by science and measurement!
