$6 C-SKY Linux Development Board Features GX6605S Media SoC with C-SKY ISA

We’ve got plenty of ultra low cost , media capable Linux boards in recent years, but most of those are based on Arm architecture. More recently RISC-V open source ISA has started to show up in various boards such as Sipeed M1, but none of those can play video, or at least don’t come with an hardware video decoder. C-Sky Linux development board does change that somewhat. It’s sold for about $6 (39 RMB) on Taobao, and $17.36 shipped on Aliexpress, and features Nationalchip GX6605S processor for DVB-S2 HD set-top boxes using C-SKY architecture, independent from RISC-V, although C-SKY is also a member of the RISV-C foundation. C-SKY Linux development board key features and specifications: SoC – Nationalchip GX6605S C-SKY ISA V1 CK610M 32-bit processor @ 574 MHz with 64MB DDR2 RAM, built-in DVB-S2/S demodulator Storage – 4MB SPI flash for bootloader and media player program Video Output – HDMI […]

RockPro64 RK3399 Board Linux Review with Ubuntu 18.04 + LXDE

Let’s do one more RK3399 Linux review using Pine64 RockPro64 development board. After shortly checking out the hardware, I’ll test Ubuntu 18.04 “Bionic” LXDE on the board, test 3D graphics acceleration, video playback, USB storage and network performance among other things on the board. RockPro64 Board Unboxing The board came in a cardboard package, and the sticker made it clear I had received the 2GB LPDDR4 version. Even after FriendlyELEC NanoPi M4 announcement, Rockchip ROCKPro64 is still the cheapest RK3399 development board around, so it should come as no surprise that the board does not come with any accessories by default. Another way to keep the price low was not to include any built-in storage apart from SPI flash, so instead most people will either boot from micro SD card or an eMMC flash module both of which need to be purchase separately. Another cost-saving is the lack of built-in […]

Bluetooth 4.0 dual-mode BLE with on-board antenna and u.FL connector for optional external antenna HW Security – Tamper-resistant dedicated crypto chip (secure element) for storing cryptographic keys, unique ID, random number generation and more 2x DF40 80-pin board to board X1 and X2 connectors with 38x GPIOs 4x UART, 3x I2C, 2x SPI, […]

FriendlyELEC NanoPC-T4 Board Kit Unboxing and Assembly

FriendlyELEC introduced NanoPC-T4 RK3399 SBC (Single Board Computer) last May for $129. The board comes with a Rockchip RK3399 hexa-core processor, 4GB RAM, 16GB eMMC flash, dual-band WiFi module and an M.2 socket with NVME (PCIe) SSD support. The company has now sent me the device with accessories for review / evaluation. In this post, I’ll check out all items received, and show how to assemble all components. NanoPC-T4 Board Kit Unboxing Let’s getting started, and open the package… I received two identical kits with two NanoPC-T4 boards, acrylic enclosure with spacers, screws and nuts, 12V/2A power supply, heatsink, and an RC-100 IR remote control. In theory, I also expected two WiFi antennas per kit since that’s part fo the kit in their website, but I did not see any. The remote control is an optional item. [Update: Ooops. I found the antennas inside the package for NanoPC-T4 board.] I’ve […]

Bootlin Releases Open Source VPU Driver for Allwinner Processors with MPEG2 and H.264 Video Decoding

At the beginning of the year, Bootlin – formerly Free Electrons – launched a crowdfunding campaign to bring open source Allwinner VPU driver to mainline Linux. VPU (Video Processing Unit) drivers are used to encode and decode videos. They were successfully in raising enough money from small donors, as well as several companies manufacturing Allwinner development boards including Olimex, Pine64, Libre Computer, FriendlyELEC, and Xunlong Software (Orange Pi). The amount raised (€31,612) was enough to assign two engineers to work on the main goals, as well as some stretch goals namely support for newer Allwinner H3, H5, and A64 processors, and H.265 video decoding. The good news is the company has now delivery the first release for their work on the main goals. The photo above illustrated a demo of Kodi running with bootlin open source Cedrus VPU driver on top of Linux 4.18-rc kernel. Both MPEG2 and H264 are […]

Design ESP32 LoRa GPS Tracker Applications with TTGO T-Beam Board

TTGO introduced a small ESP32 LoRa board with OLED display last year that is still selling  for around $14 shipped. But the company is now back with a similar board called TTGO T-Beam that does without the display, but adds GPS support, and a 18650 battery holder, so it should be ideally suited for all sorts of LoRa GPS tracking applications. TTGO T-Beam board specifications: SoC – Espressif ESP32 dual core Xtensa LX6 processor with WiFi and Bluetooth Memory – PSRAM Storage – 4MB SPI flash Connectivity 802.11 b/g/n WiFi up to 150 Mbps +  Bluetooth 4.2 Classic and LE with “3D antenna” soldered on PCB LoRa 433, 868, and 915 MHz versions with SMA antenna Transmit current – 120 mA @ +20dBm; 90 mA @ +17dBm; 29mA @ +13dBm Receive sensitivity -139dBm with LoRa & 62.5Khz & SF=12 & 146bps -136dBm with LoRa & 125Khz & SF=12 & 293bps […]

Vivo Announces TOF 3D Sensing Technology with 300,000 Sensor Points

Earlier this year, I reviewed a TOF sensor board based on STMicro VL52L0X Time-of-Flight ranging sensor that allows to measure distance accurately up to 2 meter using a 940 nm laser and a detection array with a few points to measure the time it takes for the light to travel and determine the distance. VIVO has showcased a smartphone solution leveraging time-of-flight technology at Mobile World Congress Shanghai 2018, but instead of using it for 2D measurements with a small detection array, their TOF 3D Sensing Technology creates 3D scans of objects using a whopping 300,000 sensor points. The technology will enable features & applications such as facial, gesture and motion recognition, 3D photography and extended/augmented reality. Vivo’s TOF 3D Sensing solution is said to deliver 10 times more depth of information than existing Structured Light Technology, for example used for FaceID in the latest iPhones. Vivo’s technology allows 3D […]

Visual Studio 2017 with an Embedded Linux Arm Device

This is a non-sponsored guest post written by Marc Goodner: Principal Program Manager, Microsoft, and Jeremias Cordoba: Innovation Engineer, Toradex. Today many embedded devices run some flavor of Linux as their primary operating system. This poses a challenge to developers who run Windows on their development machine. This article explains a new way to use the latest Visual Studio for C++ development on an embedded Arm Devices from a Windows Host PC using containers for the build environment. The device we are deploying to is from the Toradex Colibri Family of System on Modules using the NXP i.MX 6ULL SoC, which features an Arm Cortex A-7. As a demo project, we will connect a Bluetooth Sensor with the Toradex Colibri Module. Please note that Visual Studio support for this case is in an early state, you will see improvements from Microsoft and Toradex in the coming months. Prerequisites Colibri i.MX 6ULL […]
