Review of Firefly-RK3399 Board with Android 8.1 Firmware

Last week, I tested Android 7.1 on NanoPC-T4 Rockchip RK3399 SBC, and this week, I’ve given a try at Android 8.1 (Beta) on Firefly-RK3399 Board. Since it’s still a beta version, I’m expecting some issues and we’ll have to see how it performs at this stage of development. Firefly-RK3399 Kit Assembly I had to do some assembly before starting the board. It took me some 30 minutes to complete, so I’ll quickly go through the steps. Beside the default kit, the company also sent me a fansink ($7.9) and an M.2 to SATA board + required cable ($16) which will be part of the assembly instructions. The first step is to peel off the protective films on both sides of the acrylic case. I then fastened my own 2.5″ hard drive with four screws provided in the default kit. I then installed the M.2 to dual SATA adapter board in […]

Embedded Base Boot Requirements (EBBR) Project Aims to Standardize Booting on Embedded Systems

Desktop and server systems relies on standardized interfaces between the bootloader and the OS like UEFI and ACPI, but for embedded systems the way the bootloader, often U-boot, handles the boot flow may vary greatly between targets. Arm and its partners already worked on this in the server space with the Server Base Architecture Specification (SBSA) , and more specifically the Server Base Boot Requirements (SBBR) within the specification that requires the use of both UEFI and ACPI on servers. Arm has now done something similar with the Embedded Base Boot Requirements (EBBR) project that targets specifically embedded systems, is based on a subset of UEFI, and works with either ACPI or device tree. EBBR specification once implemented in bootloaders like U-boot or Tianocore/EDK2 should allow a single version of an OS image to boot on multiple platforms without the per-platform customization required today.. In practical terms it means the […]

How to Make a Cheap Single Channel Gateway with an ESP32 LoRa Board

Actual LoRaWAN gateways based on Semtech SX1301 concentrator can be pretty expensive, and even if you take a LoRa gateway design based on Raspberry Pi for indoor placement or experimentation, price is still around $200. A much cheaper way (~$70) is to use a single channel LoRa gateway, which as the name implies only support one channel, which limits the number of nodes, and forces you to set the nodes at the same frequency as your gateway. Those are not really suitable for commercial offerings, but if you manage your own gateway and nodes that should be usable. If you only plan to implement a network with a dozen nodes or so, you could even use much cheap ESP32 LoRa board like the ESP32 LoRa 1-Channel Gateway sold on Sparkfun for $29.95. Hardware specifications: Connectivity WiFi and Bluetooth 4.2 LE via ESP32-WROOM-32 module with integrated PCB antenna LoRa @ 868 […]

Pocket Science Lab (PSLab) is an Open Source Hardware Electronics Lab

Last Saturday I created a virtual schedule for the Embedded Linux Conference Europe 2018 where I listed some of the sessions relevant to myself and hopefully regular readers of CNX Software, but due to scheduling conflicts one talk did not make it to the list: “Pocket Science Lab – An Open Source Hardware for Electronics Teaching & Learning” by FOSSASIA. The project is also referred to as PSLab, and aims to “create an Open Source hardware device that can be used for experiments by teachers, students, and citizen scientists to learn and teach electronics”. It looks interesting enough so let’s have a closer look. The project is inspired by the earlier expEYES project that combines with Raspberry Pi or other Linux platform to create an electronic labs, and the work by the Open Science Hardware community. PSLab key features and specifications: MCU – Microchip PIC24EP256GP204 16-bit microcontroller @ up to […]

Access SAMBA Shares in Android with File Browser by Astro

My go-to Android file manager used to be ES File Manager until… today. The free version of the app already had some annoying floating widgets and all sort of things you would be expect to be enabled by default, but the latest version requires you to install an app to enable SAMBA 2.0 support. I tried to keep up with the requirements, but the ad relies on Google Play services which was not installed in the firmware I used. The easiest way to solve the issue is probably to pay $2.99 for the PRO version, but for firmware without Google Play services it might not be possible to sideload it. So instead, I decided it was time to look for an alternative file manager with SAMBA support, since that’s the main feature I use in an Android file manager while doing reviews. I found two candidates File Commander – Free […]

ANAVI Play pHAT OSHW Board Adds 8 Buttons, I2C Headers to Raspberry Pi Boards (Crowdfunding)

Leon ANAVI has been learning KiCad open source EDA suite in his spare time, and developed several Raspberry Pi (p)HAT add-on boards such as ANAVI pHAT Light to control LED RGB strips, or ANAVI Infrared pHAT to handle IR signals. All his boards are open source hardware, and come with source code, and decent documentation as explained in the two aforelinked reviews. Leon has now come with another variant of his open source hardware certified add-on boards with ANAVI Play pHAT designed for playing games on the Raspberry Pi 3 / Pi Zero W boards, or other boards with a 40-pin header, thanks to 8 buttons, and just like his previous designs, three I2C headers are also included to connect sensors. Key specifications and features of the board: Gamepad with eight buttons for playing retro games 3x I2C header for sensors EEPROM with device tree binary overlay OSHW Certification – […]

Tranquil PC’s AMD Ryzen Embedded Mini PC Supports Up to 4 Displays

AMD Ryzen Embedded V1000 processor family was introduced last February, but if you’d wanted to buy a Ryzen Embedded mini PC today, you’ struggle to do so at least for a retail model. One option is to get an UDOO Bolt V3/V8 development board together its metal case and assemble the mini PC yourself. The solution was launched on Kickstarter however, and will only start shipping in December 2018 if everything goes according to plans. If you’d rather get a Ryzen Embedded mini PC a little earlier, Tranquil PC’s Mini Multi display PC may be an option with a choice of three Ryzen embedded V1000 processors, a fanless design, and support for up to 4 independent displays. Transquil PC’s mini multi-display PC Basic/Advanced/Advanced+ specifications: SoC Basic – AMD Ryzen Embedded V1202B, 2C/4T @ 2.3 / 3.2GHz, TDP: 12W-25W Advanced – AMD Ryzen Embedded V1605B, 4C/8T @ 2.3 / 3.6GHz, TDP: […]
