Advantech Elkhart Lake mini-ITX motherboard offers triple display support, dual LAN, eight USB and six COM ports

We’ve seen a fair amount of Intel Elkhart Lake platforms including modules, 3.5-inch SBCs, Pico-ITX boards, and embedded mini PCs, but so far, I had not noticed any Elkhart Lake mini-ITX motherboard. Advantech AIMB-218 motherboard offers a choice of low-power Atom, Celeron and Pentium Elkhart Processor, and thanks to the larger form factor plenty of I/Os including four display interfaces (DP++/HDMI/eDP/LVDS) supporting up to three display, eight USB port, six serial COM port, and dual Gigabit Ethernet. Advantech AIMB-218 specifications: SoC (one or the other) – Intel Atom x6413E quad-core processor @ 1.50 GHz / 3.0 GHz (Turbo) with 16EU Intel UHD graphics; 9W TDP Intel Celeron N6211 dual-core processor @ 1.20 GHz / 3.0 GHz with 16EU Intel UHD graphics; 6.5W TDP Intel Celeron J6413 quad-core processor @ 1.80 GHz / 3.0 GHz with 16EU Intel UHD graphics; 10W TDP Intel Pentium J6426 (new part) quad-core 2.0 GHz / […]

Encoding and decoding AVIF pictures with open-source software & libraries

One of the new features of Android 12 is support for the AVIF file format that provides much smaller files at the same level of quality. Jake Archibald has done a great job comparing AVIF format to JPEG, WebP, and other still picture formats, and the results are really impressive. Besides Android 12, AVIF is already supported in Chrome browser, will be enabled by default in Firefox 86, but here’s we’ll look at some of the open-source programs and libraries that allow you to manipulate AVIF pictures. With libavif library, AOMedia has published a reference implementation in C, together with avifenc and avifdec tools, that rely on various codecs, but it appears rav1e is recommended for encoding AVIF picture, while dav1d is the best choice for AVIF decoding. libavif will not automatically build the codec, and they need to be enabled in CMakeLists.txt

option(AVIF_CODEC_AOM "Use the AOM codec for encoding/decoding (see AVIF_CODEC_AOM_DECODE/AVIF_CODEC_AOM_ENCODE)" OFF)
option(AVIF_CODEC_DAV1D "Use the dav1d codec for decoding" ON)
option(AVIF_CODEC_LIBGAV1 "Use the libgav1 codec for decoding" OFF)
option(AVIF_CODEC_RAV1E "Use the rav1e codec for encoding" ON)
option(AVIF_CODEC_SVT "Use the SVT-AV1 codec for encoding" OFF)

option(AVIF_CODEC_AOM "Use the AOM codec for encoding/decoding (see AVIF_CODEC_AOM_DECODE/AVIF_CODEC_AOM_ENCODE)" OFF)

option(AVIF_CODEC_DAV1D "Use the dav1d codec for decoding" ON)

option(AVIF_CODEC_LIBGAV1 "Use the libgav1 codec for decoding" OFF)

Fuzix Unix-like operating system ported to Raspberry Pi Pico and ESP8266

The Raspberry Pi Pico is not compatible with Linux, but now supports another Unix-like operating system known as Fuzix. Alan Cox’s Fuzix is a Unix-like operating system for older devices with less performance capacity. David Given’s two recent posts have brought to the attention about the operating system’s compatibility with ESP8266 MCU and Raspberry Pi Pico. Fuzix operating system has a kernel which is the central core of the system. Also, it has a C compiler and a set of core applications similar to the UNIX filesystem. The Raspberry Pi Pico port comes with many benefits like a well-structured Unix filesystem with its compatibility for SD cards through the SPI interface. Hence, supporting the Fuzix operating system. The full set of Fuzix binaries is available through a serial console to UART0. Porting Fuzix to ESP8266 The post on “Porting Fuzix to the ESP8266” addresses the MCU’s support for the Fuzix […]

Cherry Pi PC SBC is an Orange Pi PC clone selling for $16.5 and up

Orange Pi PC is an Allwinner H3 SBC that was launched in 2015 for as little as $15 plus shipping (now $17.42 with 1 GB RAM), and made by a company called Shenzhen Xunlong Software. The next year, the company launched Orange Pi PC Plus with 8GB eMMC flash and WiFI connectivity for $20 (now $25.54). It appears another company named “Shenzhen LC Technology” has designed a board with similar specifications & layout, so not technically a clone, but close enough. Meet Cherry Pi SBC. Cherry Pi PC V7 SBC specifications with highlights in bold or strikethrough showing the differences with Orange Pi PC: SoC – Allwinner H3 quad-core Cortex A7 processor with an Arm Mali-400MP2 GPU System Memory – 512MB or 1GB DDR3 Storage – MicroSD card slot up to 64GB, optional 8GB eMMC flash, Video Output – HDMI 1.4 and AV ports Audio I/O – HDMI, AV port, […]

Android 12 developer preview released – What’s New?

Google releases a new version of Android every year, and the company is now usually releasing a developer preview in February to allow feedback and testing from app developers. So here we are with the Android 12 developer preview having just been released by Google with changes ranging from trust and safety to media transcoding to support for AVIF image format. Android 12 highlights: Performance Improved Binder IPC calls – Google engineers have had a look at latency and workload distribution, and made optimizations that reduce the median experience. This has yielded roughly a 2x performance increase on Binder calls overall, and up to a 47x improvement in refContentProvider(), 15x in releaseWakeLock(), and 7.9x in JobScheduler.schedule(). Foreground service optimizations – To ensure a better experience for users, foreground service starts from the background will be blocked for apps that are targeting the new platform. Android 12 will also delay the […]

Open-source H.265/HEVC Hantro G2 decoder driver added to NXP i.MX 8M in Linux

H.265 Linux open-source driver NXP iMX 8M Quad

Getting open-source multimedia drivers on Arm Linux is one of the most difficult tasks, that’s why there’s no much talk about open-source GPU drivers for 2D & 3D graphics acceleration, but work on video hardware decoding and encoding is also a challenge. We’ve previously seen Bootlin work on Cedrus open-source driver for Allwinner VPU (Video Processing Unit), but Collabora has been working on open-source drivers for VeriSilicon’s Hantro G1 and G2 VPU found in some Rockchip, NXP, and Microchip processors. The company previously managed to have Hantro G1 open-source driver for JPEG, MPEG-2, VP8, and H.264 codecs, but H.265/HEVC relies on Hantro G2, and the patch for H.265 hardware video decoding on NXP i.MX 8M Quad has just been submitted to mainline Linux. Benjamin Gaignard explains more in his commit message: The IMX8MQ got two VPUs but until now only G1 has been enabled This series aim to add the […]
