Raspberry Pi Compute Module 4 Coming Next Year with PCIe/NVMe Support

The Raspberry Pi 4 features a Broadcom BCM2711 processor with Cortex-A72/A53 cores that makes it competitive against other SBC’s based on Rockchip RK3399 or Amlogic S922X/A311D processors. The new processor also happens to have a PCIe interface, but it’s not exposed on the board since the interface is used by VIA VL805 PCIe USB 3.0 controller for the four USB 3.0 ports on the little computer. At the time, we expected the PCIe interface to be exposed in future Raspberry Pi boards or a Raspberry Pi Compute Module 4. But some people did not feel like waiting and instead hack the Raspberry Pi 4 SBC to access the PCIe interface. That hack is clearly not for everyone though… But based on a recent interview of Eben Upton with Tom’s Hardware we got pretty much confirmation that the Raspberry Pi Compute Module 4 will be coming next year, and expose PCIe […]

GloDroid Brings Android 10 OS to Raspberry Pi 4, Orange Pi SBC’s, PinePhone, and PineTab

The community of developers working on software for single board computers often prefer to focus on Linux support, as companies will often provide Android firmware images. But those Android OS images are often not maintained at all, so we’ve seen some projects like the past such as H3droid bringing a better Android OS to Allwinner H3 and H2+ boards and devices. The project is still using Android 4.4 KitKat and that’s getting old with some apps like the latest version of Kodi not working anymore. But a new project has just been brought to my attention with GloDroid leveraging AOSP to bring Android 10 to various Allwinner based boards and platforms, as well as Raspberry Pi 4B. List of supported Allwinner hardware: Allwinner H3 (32-bit) based – Orange Pi Plus 2 SBC, Orange Pi Plus 2E board, Orange Pi PC Allwinner H5 (64-bit) based – Orange Pi Prime, Orange Pi […]

Mythic Beasts, miniNodes Offer Raspberry Pi 4 Hosting Services

Mythic Beats is the company offering hosting services for the Raspberry Pi website, and following Eben Upton proposal they decided to host the website on eighteen Raspberry Pi 4 boards, fourteen of which used as LAMP (Linux, Apache, MySQL, PHP) servers, as well as two used as static servers with Apache, and the final two used as memory store using memcache. Two days before Raspberry Pi 4 8GB RAM launch, they tested the implementation with “normal” traffic (e.g. around one million visitors a day), and the day of the launch, tens of millions visitors came to the website, and it failed, but not because of a failure of the Raspberry Pi cluster, but instead due to a Cloudflare glitch. This is all explained in Raspberry Pi blog. This is all for internal use, but you could also get your own hosted Raspberry Pi 4 board, as Mythic Beast recently added […]

Raspberry Pi SBC Now Supports OpenVX 1.3 Computer Vision API

OpenVX is an open, royalty-free API standard for cross-platform acceleration of computer vision applications developed by The Khronos Group that also manages the popular OpenGL ES, Vulkan, and OpenCL standards. After OpenGL ES 3.1 conformance for Raspberry Pi 4, and good progress on the Vulkan implementation, the Raspberry Pi Foundation has now announced that both Raspberry Pi 3 and 4 Model B SBC’s had achieved OpenVX 1.3 conformance (somehow dated 2020-07-23). Raspberry Pi OpenVX open-source sample implementation passes the Vision, Enhanced Vision, & Neural Net conformance profiles specified in OpenVX 1.3 standard. However, it is NOT intended to be a reference implementation, as it is not optimized, production-ready, nor actively maintained by Khronos publically. The sample can be built on multiple operating systems (Windows, Linux, Android) using either CMake or Concerto. Detailed instructions are provided for Ubuntu 18.04 64-bit x86 and Raspberry Pi SBC. Here’s the list of commands to […]

Raspberry Pi VideoCore IV Boards Get an Unofficial Vulkan Driver Good Enough to Play Quake 3

The Raspberry Pi Foundation is collaborating with Igalia to work on everything related to graphics support for VideoCore VI GPU found in Raspberry Pi 4’s Broadcom BCM2711 SoC. This lead to OpenGL ES 3.1 conformance at the beginning of the year, and good progress with Raspberry Pi 4 Vulkan support. There’s no plan to work on an official Vulkan driver for earlier Raspberry Pi boards with VideoCore IV GPU, but since the Raspberry Pi Foundation released open-source VideoCore IV driver and documentation several years ago, it’s, in theory, possible for skilled developers to improve on it. That’s exactly what Martin Thomas, an NVIDIA engineer, has done in his spare time, and after two years of work, a Vulkan driver for Raspberry Pi VideoCore IV board – RPi-VK-Driver – has been released on Github. Pi-VK-Driver implements a subset of the Vulkan, and since it is not fully conformant to the standard […]

Checking Out Raspberry Pi OS 64-Bit on Raspberry Pi 4 8GB RAM

The Raspberry Pi 4 with 8GB RAM launched a couple of weeks ago together with the beta version of Raspberry Pi OS 64-bit. Note that you should currently use the 32-bit version of Raspberry Pi OS (previously known as Raspbian) as the 64-bit still has bugs and missing features, but I want to find out the current progress, so I installed raspios_arm64-2020-05-28/2020-05-27-raspios-buster-arm64.zip and had no problem to boot the board. Raspberry Pi OS 64-bit System Information After going through the setup wizard in the desktop environment to configure the language, time, networking, etc…, and make sure the OS is updated, I checkout some information:

pi@raspberrypi:~ $ cat /proc/cpuinfo

I do have a Raspberry Pi 4 Model B Rev 1.4 with 8GB Memory (revision: d03114), the image comes with a 64-bit Linux kernel:

and we do get a 64-bit rootfs.

All good. Known issues Before starting the review, let’s make ourselves aware […]

CrowPi2 Raspberry Pi 4 Laptop Doubles as Electronics Learning Kit (Crowdfunding)

CrowPi2 Raspberry Pi 4 Laptop with Detachable Keyboard

CrowPi portable learning kit for Raspberry Pi 3 B+ and Pi Zero boards was launched in 2018. It comes with a 7″ display, several sensors, buttons, a breadboard, and more all packed in a small suitcase. Elecrow has now started a new crowdfunding campaign on Kickstarter to fund the second generation portable electronics learning kit: CrowPi2 which looks much more like a laptop than a suitcase found in the first model thanks to a large display, and a detachable keyboard placed on top of the electronic prototyping/learning area. It’s also more powerful thanks to the latest Raspberry Pi 4 SBC. CrowPi2 specifications: Compatible Raspberry Pi boards – Raspberry Pi 3B/B+, Raspberry Pi 4 Display – 11.6-inch 1920×1080 IPS screen Camera – 2MP camera Audio – Built-in microphone and stereo speaker; 3.5mm audio jack Keyboard – 2.4GHz detachable wireless keyboard (QWERTY only) with touchpad Sensors and Modules under the keyboard: Displays […]
