The PL-R5 (with a Compute Module 5 inside) does not use a microSD card. Instead, the bootloader is updated by running a command to write a new .bin image file.This article explains how to update the bootloader on the PL-R5.
Raspberry Pi OS Trixie differs significantly from previous versions, so some older information is no longer applicable.
In this article, I tested the read-only configuration again in a Trixie environment.
The Raspberry Pi CM5 is available in models with built-in Wi-Fi. However, it is often said that the onboard antenna provides relatively weak wireless performance. To see whether an external USB Wi-Fi adapter offers a better alternative, we decided to put it to the test.
A stereo camera is a device equipped with multiple cameras and functions, using left-right parallax in a way similar to human vision. Its primary purpose is to acquire distance information in real time.
The stereo camera used in this test was the Orbbec Gemini 335L. As shown in the image, it consists of multiple components, including infrared cameras and a laser projector.
In this case, it is a slightly special camera called ToF, which simply put, is a camera that can tell the depth of the object being photographed.
Configure each of the three USB OTG functions (USB Ethernet, USB serial communication, and USB storage) individually.
USB OTG (On-The-Go) is the ability for a single USB port to become both a Host and a Device.
By making the OS part read-only, writing to storage is greatly reduced, extending the life of the storage media. In addition, it increases the probability of preventing damage to the OS part in the event of a sudden power failure.
Partitions on external media can be modified while the system is running.However, the partition that the OS is currently running from cannot be modified directly.You must access it from another system. Here, the OS is written in Raspberry Pi Imager for use with Raspberry Pi devices such as Raspberry Pi 5 and CM5.The same partitioning procedure can be used for the Raspberry Pi OS as well as Ubuntu Desktop. Split into partitions Instead of partitioning from scratch, write the OS as usual with the Raspberry Pi Imager.Another partition is created after startup. Raspberry Pi OS Write Activate the written microSD card or other device as usual.Once activated on the Raspberry…
The PiShrink tool software allows you to reduce the size of the Raspberry Pi OS image file that you have backed up in its entirety beforehand. The reason why it is necessary to reduce the size of the image file is because the file size will inevitably become huge, making it difficult to save and handle. The backup image file for the Raspberry Pi Compute Module 4 that we have prepared is about 30 GB. Multiple backup files require even more storage space. Even if the files are stored in a different location, it will take a considerable amount of time to move or copy the files. If the file…
