Rockchip RK3588 specifications revealed – 8K video, 6 TOPS NPU, PCIe 3.0, up to 32GB RAM

Rockchip RK3588 is one of the most anticipated processors for the year on this side of the Internet with the octa-core processor features four Cortex-A76 cores, four Cortex-A55 cores, an NPU, and 8K video decoding support. [Update December 2021: check out our post with the RK3588 datasheet for the latest details about the processor] The roadmap shows an expected launch date in Q3/Q4 2020, but sadly the release date will be pushed back in the future. Having said that, the Rockchip Developer Conference (RKDC) is now taking place, and the company has put up a poster that reveals a bit more about the processor. That means we now have more detailed Rockchip RK3588 specifications: CPU – 4x Cortex-A76 and 4x Cortex-A55 cores in dynamIQ configuration GPU – Arm Mali “Odin” MP4 GPU AI Accelerator – 6 TOPS NPU 3.0 (Neural Processing Unit) VPU – 8Kp60 video decoding support, 8Kp30 encoding […]

Hantro H1 hardware accelerated video encoding support in mainline Linux

With the increasing need for video encoding, there are some breakthrough developments in hardware-accelerated video encoding for Linux. Bootlin has been working on the implementation of Hantro H1 hardware accelerated video encoding to support H.264 encoding on Linux which follows the company’s work on the previously-released open-source VPU driver for Allwinner processors. Hantro H1 Hardware Hantro H1 is a common hardware H.264 encoder, it can also do VP8 and JPEG. It is found in a few ARM SoCs including a lot of Rockchip (RK3288, RK3328, RK3399, PX30, RK1808) and NXP (i.MX 8M Mini). Depending on the version, it can support up to 1080p at 30 or 60 fps. Here we can see different blocks used for encoding. Hantro H1 is a stateless hardware implementation which means it has no microcontroller or firmware running. As can be seen in the diagram, it has a pre-processor that can do things like cropping, […]

ELBE is a simpler alternative to Yocto/OpenEmbedded and Buildroot

To support embedded design, there are several options when it comes to choosing an operating system (OS). Some of the traditional approaches to building custom Linux systems is to use built systems such as Yocto/OpenEmbedded or Buildroot. The options available for system integration include building everything manually, binary distributions (Debian, Ubuntu, Fedora, etc.), and build systems (Buildroot, Yocto, PTXdist, etc.). The major drawback of build systems is that they are not as easy as a binary distribution and also the build time is more. Why was ELBE born? In the early days, the embedded devices had 4MiB flash and 16MiB of RAM. With these specifications, people started to hack a root file system for their devices. But in some cases, they had to start with building a cross-toolchain first. For this, tools like OpenEmbedded, Buildroot are good as long as they are well maintained. For this, a lot of libraries […]

Reading Vehicle OBD-II data through CAN within a containerized application in Embedded Linux

telematics applications overview-GNSS CAN Cloud embedded Linux

CNXSoft: This is a guest about OBD-II and CAN support in embedded Linux by Andre Márcio de Lima Curvello, Sr. FAE and Technical Evangelist, Toradex A connected world makes it possible to track your online orders being shipped to your home through your smartphone in real-time, and getting information about your vehicle such as tire pressure, outside temperature, and even details like if a lamp is broken – has begun to be possible via smartphones in modern vehicle models. But behind the magic of knowing where the truck carrying your package is at all times and other details of the vehicle, there is a very complex world made of embedded devices ‘talking’ to each other so the information makes its way from the device to you. In this article, you will learn how to create an application to communicate with a vehicle through CAN via the OBD-II standard. We use […]

Quantum Mini devkit combines Allwinner H3 M.2 SoM with baseboard

Quantum Mini may be yet another Allwinner H3 Arm Linux development board, but what makes it special is the company used the standard M.2 Key-A 22mm form factor to create Quark-N Allwinner H3 system-on-module with storage and memory. The kit is completed by Atom-N baseboard that takes the M.2 module and offers two USB 2.0 ports, one USB Type-C port, as well as 2.4 GHz WiFi 4 and Bluetooth 4.0 connectivity, and a MicroSD port for additional storage. Quantum Mini development kit specifications: Quark-N SoM SoC – Allwinner H3 quad-core Cortex-A7 @ 1GHz with Mali-400MP2 GPU System Memory – 512MB LPDDR3 Storage – 16GB eMMC flash Interfaces exposed via M.2 connector – Ethernet, SPI, I2C, UART, GPIO, MIC, LINEOUT Dimensions – 31 x 22mm (6-layer PCB) Temperature Range – 0-80°C Atom-N baseboard M.2 socket for Quark-N system-on-module Storage – MicroSD card slot Display – TFT display Connectivity – 2.4 GHz […]

LibIIO – Library for interfacing Linux industrial I/O devices

For more than 6 years, the LibIIO library has existed to ease the development of software interfacing Linux Industrial I/O (IIO) devices. It is part of the Linux Kernel and a subsystem that provides support for devices like analog to digital or digital to analog converters (ADCs, DACs). This subsystem includes ADCs, accelerometers, pressure sensors, color, light and proximity sensors, temperature sensors, RF transceivers, and many more. You can use LibIIO natively on an embedded Linux target. It is cross-platform, supporting Linux, Windows, and Mac OS. Analog Devices Inc. was the main company behind LibIIO development, which is currently an active open-source library, which many people have contributed to. What does LibIIO do? LibIIO will identify the channels that belong to each device. It will assign specific attributes, one for the channels and one for the devices. Then, it will also create a context that is a place where all […]
