Rock Pi 4 SBC Runs GNOME & KDE Plasma using Panfrost Open Source GPU Driver & Wayland

One of the highlights of Linux 5.2 release was support for two new Arm Mali GPU open-source drivers, namely Lima for Mali-4xx GPU, and Panfrost for the Midgard Mali-T6xx/7xx/8xx series, and the more recent Bifrost Mali-Gxx GPUs. Collabora worked on the release and was donated a few Rock Pi 4 boards from Radxa directly to work on the project. For those who are not familiar, Rock Pi 4 board is powered by a Rockchip RK3399 processor with a Mali-T860MP4 GPU that is supported by Panfrost open source GPU driver. The company managed to have Debian 10 Buster running on Rock Pi 4 using 3D graphics acceleration thanks to Panfrost drivers on both GNOME and KDE Plasma desktop environment, as well as Weston Wayland compositer. The good news is that you can build Rock Pi 4 images by yourself using Debos with the following commands:

git clone https://gitlab.collabora.com/rockpi/rockpi4
cd rockpi4
docker run --rm --interactive --tty --device /dev/kvm --workdir /recipes --mount "type=bind,source=$(pwd),destination=/recipes" --security-opt label=disable godebos/debos --scratchsize=8G rockpi4.yml

git clone https://gitlab.collabora.com/rockpi/rockpi4

cd rockpi4

docker run --rm --interactive --tty --device /dev/kvm --workdir /recipes --mount "type=bind,source=$(pwd),destination=/recipes" --security-opt label=disable godebos/debos --scratchsize=8G rockpi4.yml

Alternatively, you could directly download […]

Actcast Combines IFTTT-like Service with AI and Raspberry Pi 3 / Zero

In a report on April 30, 2017, Idein had developed GPGPU accelerated object recognition for the Raspberry Pi platform. That development led to the beta release of the ActCast IoT platform, which was announced on July 29, 2019, and uses deep learning algorithms for object and subject recognition. The program is for use with IoT and AI. The idea is to increase performance and link the system to the web for even more solutions. What it Does The use of physical world information in IoT projects has many applications. Such as a doorbell that sees a person, can then recognize the person. Ultimately letting the user know over the web through a smartphone, the person should be let in. And then the system unlocks the door. So Actcast is a bit like IFTTT with artificial intelligence / computer vision capabilities. Edge Computing Bringing the source of data closer to the […]

BeagleBone Green Gateway SBC Adds Octavo OSD3358 SiP, Ethernet, and a DC Jack

BeagleBone Green Wireless was launched in 2016 as an alternative to the official BeagleBone Green with WiFi & Bluetooth connectivity, and some extra USB ports meaning the Ethernet port had to go. The Linux SBC was based on Texas Instruments Sitara AM3358 processor and a 512 MB RAM chip. Seeed Studio has been working on an update of the board named BeagleBone Green Gateway that combines the processor, the RAM chip, and more components into one thanks to Octavo Systems OSD3358 SiP. The new board also adds Ethernet, a DC jack for power instead of just relying on micro USB, and an I2C RTC chip and battery. BeagleBone Green Gateway specifications with changes highlighted in bold: SiP – Octavo Systems OSD3358 with Texas Instruments AM3358 Arm Cortex-A8 processor @ 1.0 GHz, 2×32-bit 200-MHz programmable real-time units (PRUs), 3D graphics accelerator, 512MB DDR3 SDRAM, 4KB EEPROM, and integrated power management Storage […]

Orange Pi Zero LTS SBC Launched for $8.49 and Up

Orange Pi Zero LTS is an update to Orange Pi Zero Allwinner H2+ board with the same specifications, but tweaks to the hardware that Shenzhen Xunlong Software claims lower power consumption and reduce heat. The SBC supports Armbian’s Debian and Ubuntu images, and best suited for headless applications that require network connectivity via Ethernet and/or WiFi such as smart speakers. The board also features one USB port, and two I/O headers for expansion. The good news is that you can now buy Orange Pi Zero LTS for the same price as the original model, namely $8.49 for the 256MB RAM version, and $10.49 for the 512MB model$10.49 for the 512MB model, excluding shipping costs ($4.73 to my location). Here’s a reminder of Orange Pi Zero LTS (v1.5) specifications: SoC – Allwinner H2+ quad-core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU @ 600 MHz System Memory – 256 to […]

How to Overclock Raspberry Pi 4 to 2.0 GHz

Yesterday I played with my new “ICE Tower CPU cooling fan” for Raspberry Pi 4 which cools the board just great but is clearly over the top. Regular reader and commenter m][sko mentioned it was possible to overclock Raspberry Pi 4 to 2.0 GHz after a firmware upgrade. That looks like a perfect task for my new fansink! I’ve upgraded both the firmware and operating system:

sudo rpi-update
sudo apt dist-upgrade

1 2	sudo rpi-update sudo apt dist-upgrade

then edited /boot/config.txt as root (sudo) to add the following lines to boost the maximum frequency to 2.0 GHz:

force_turbo=0
arm_freq=2000
over_voltage=6

force_turbo=0

arm_freq=2000

over_voltage=6

Do not try to set force_turbo=1, as while it would allow to further boost the voltage, it will change a fuse in the chip, and it will void your warranty. We can now reboot the board to validate the settings, and check those are applied:

vcgencmd get_config int | grep "arm\|over"
arm_freq=2000
over_voltage=6

vcgencmd get_config int | grep "arm\|over"

arm_freq=2000

over_voltage=6

Good. At idle the frequency is lower, but that normal:

vcgencmd measure_clock arm
frequency(48)=666826176

1 2	vcgencmd measure_clock arm frequency(48)=666826176

Voltage is set to 1.0335V:

vcgencmd measure_volts
volt=1.0335V

1 2	vcgencmd measure_volts volt=1.0335V

LyRa is a Raspberry Pi CM3L based Handheld Game Console (Crowdfunding)

The LyRa handheld game console is the first of its kind to carry a Raspberry Pi CM3L module inside. We reported on the Raspberry Pi Compute Module 3 Light in early 2017, and its significant features and abilities. The LyRa is being developed by Creoqode who started their campaign on Kickstarter in July 2019. The campaign has already surpassed its funding goal, and it looks like the LyRa will become a reality. The LyRa comes in two versions 1. RTG – Ready-To-Go which is a completely assembled and ready to play handheld game console, computer and entertainment console. 2. DIY – Do-It-Yourself version comes in pieces that can be made into a fully functioning handheld game console in about 15 minutes. The unit features a Raspberry Pi CM3L module which is able to emulate literally hundreds of classic game consoles and games. The unit can attach through HDMI to a […]

N-Fuse Launches Raspberry Pi 3B+ LoRaWAN Gateway with PoE Support

PoE enabled Raspberry Pi 3B+ based LoRaWAN™ Gateway

Raspberry Pi is everywhere, and this small size single-board computer has reshaped technology and STEM education. The launch of the recent Raspberry Pi 4 is evident in the success and continuous growth. The Raspberry Pi 3B+ has seen so much success in several maker’s projects, while not the most powerful SBC in the market, but undoubtedly one of the most popular. I once put together an AI-powered mobile robot using just a Raspberry Pi 3B+, an RPLidar A2, and Raspberry Camera which was way capable of so many things. Another exciting Raspberry Pi end product is the “PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway” from n-fuse. The PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway as called by n-fuse is a LoRaWAN gateway based on the Raspberry Pi 3B+, the LRWCCx-MPCIE Concentrator, and the SBCPoE RPI Hat. It supports both the Europe 868Mhz and America 915Mhz frequency (you have […]
