Raspberry Pi 4 V3DV graphics driver achieves Vulkan 1.0 conformance

Just a couple of weeks ago, we reported on the status of Raspberry Pi 4 Vulkan driver & future plans based on a presentation made by Igalia at the Open Source Summit 2020 at the end of October. At the time, the V3DV Vulkan Mesa driver for Raspberry Pi 4 was merged into Mesa, passed over 100,000 tests in the Kronos Conformance Test Suite (CTS), and was said to implement the full Vulkan 1.0 API. So it should come as no surprise that Khronos has now declared the Raspberry Pi drivers to be conformant with Vulkan 1.0 specifications. This was tested in Raspberry Pi OS with Linux 5.4.51 using X11 display server at 1920×1080 resolution on Raspberry Pi 4. Vulkan 1.0 conformance means the V3DV Mesa driver has passed all tests from Khronos CTS and should be compatible with most applications using this version of the API. The drivers will […]

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, […]

SolidRun launches i.MX 8M Plus SOM and devkit for AI/ML applications

SolidRun already offers NXP based solutions with AI accelerators through products such as SolidRun i.MX 8M Mini SoM with Gyrfalcon Lightspeeur 2803S AI accelerator, or Janux GS31 Edge AI server with NXP LX2160A networking SoC, various i.MX 8M SoCs and up to 128 Gyrfalcon accelerators. All those solutions are based on one or more external Gyrfalcon AI chips, but earlier this year, NXP introduced i.MX 8M Plus SoC with a built-in 2.3 TOPS neural processing unit (NPU), and now SolidRun has just unveiled the SolidRun i.MX 8M Plus SoM with the processor together with development kits based on HummingBoard carrier boards. Specifications: SoC – NXP i.MX 8M Plus Dual or Quad with dual or quad-core Arm Cortex-A53 processor @1.6 GHz (industrial) / 1.8 GHz (commercial), with Arm Cortex-M7 up to 800MHz, Vivante GC7000UL 3G GPU (Vulkan, OpenGL ES 3.1, OpenCL 1.2), 2.3 TOPS NPU, 1080p60 H.264/H.265 video encoder, 1080p60 video […]

Box86 is an x86 Emulator for Raspberry Pi and other 32-bit Arm platforms

Last week, we wrote about Raspberry Pi 4 Vulkan project status and future plans, and one person commented they are currently trying to get dxvk to work Box86, and that CNX Software should write about the latter. Cool, but what does that mean? dxvk is an open-source Vulkan-based implementation of D3D9, D3D10, and D3D11 for Linux, and Box86 is a Linux userspace x86 emulator that works on 32-bit Arm targets like the Raspberry Pi SBC. Nice, and I remember I ran x86 Linux and Windows on Raspberry Pi a few years ago using a closed-source commercial program called Exagear, but having an open-source solution is even better. That means 64-bit Arm is not supported at all, and Box86 can not even be built for Aarch64 targets. Since many x86 games require OpenGL, as opposed to OpenGL ES, Box86 works best in conjunction with gl4es. By installing Box86 on Raspberry Pi […]

Intel unveils eASIC N5X Structured ASIC, and the Open FPGA Stack

Intel’s virtual FPGA Technology Day 2020 is taking place today, and the company made two announcements before the event. First, the company introduced the new Intel eASIC N5X structured eASIC family with an Intel FPGA compatible hard processor system to design to quickly create applications across 5G, artificial intelligence, cloud, and edge workloads. In addition, Intel also announced the Intel Open FPGA Stack (aka Intel OFS), a scalable, open-source (intel calls it “source-accessible”) hardware and software infrastructure available through git repositories design to ease the work of hardware, software, and application developers. Intel eASIC N5X eASIC N5X is the first structure ASIC from the company to integrate an Intel FPGA compatible Quad-core Armv8 hard processor system. The new chips will help customers bring custom solutions faster to market compared to traditional ASICs thanks to the FPGA fabric, and at a cheaper cost and with up to 50% lower core power […]

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 […]

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 […]
