Beelink BT4 Mini PC Review – Slow, Buggy, Fan-cooled, and Overheating

Intel’s low-cost chip shortage has been so bad that Beelink has had to demothball some Atom chips when creating their new mini PC the Beelink BT4. This is one of the cheapest new mini PCs recently launched and uses the somewhat now old Cherry Trail Intel Atom x5-Z8500 CPU which was launched at the start of 2015 and is a quad-core 4-thread 1.44 GHz processor boosting to 2.24 GHz with Intel’s HD Graphics. The BT4 is the same form factor as the more recent Beelink mini PCs being a half-thick ‘NUC’ style device physically consisting of a 120 x 120 x 22 mm (4.72 x 4.72 x 0.87 inches) plastic rectangular case. This is not a passive device as it contains a small fan that stays on after the device has been shut down. The front panel has only a blue ‘power’ LED and the rear panel includes the power […]

Year 2019 in Review – Top 10 Posts and Stats

2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the […]

Some Interesting Talks from FOSDEM 2020 Schedule

We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]

Ubuntu 18.04 on Beelink Gemini J45 Mini PC (Fix and Review)

When I recently reviewed the Beelink J45 (aka Beelink Gemini J), a mini PC that uses the slightly older Intel Apollo Lake Pentium J4205 processor, whilst Windows 10 Pro ran fine it was unsuitable for Ubuntu because after installation the system became unstable and problems were encountered when running anything that loaded the system. The main issue was that when connected via wired-ethernet performing a command like ‘sudo apt upgrade’ would cause the ethernet to drop after which only a reboot would restore the connection. At the time it, was unclear what the cause was however a solution to the issue was posted by ‘gambetta’ on the Beelink forum. Basically it consists of installing the r8168 module which is the Linux device driver released for RealTek RTL8168B/8111B, RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D, RTL8168DP/8111DP and RTL8168E/8111E Gigabit Ethernet controllers with PCI-Express interface. To paraphrase the ‘README.Debian’ file, you use ‘r8168-dkms because the in-kernel […]

RISC-V based PolarFire SoC FPGA and Devkit Coming in Q3 2020

Microsemi unveiled PolarFire FPGA + RISC-V SoC about one year ago, but at the time, development was done on a $3,000 platform with SiFive U54 powered HiFive Unleashed board combined with an FPGA add-on board from Microsemi. I’ve now been informed that Microchip has announced its Linux-capable PolarFire FPGA+RISC-V SoC would start shipping in Q3 2020 at the RISC-V summit and that a development kit will be sold for a few hundred dollars. PolarFire SoC FPGA   PolarFire SoC FPGA key features and specifications: Mid-Range FPGA optimized for Low Power High-speed serial connectivity with built-in multi-gigabit/multi-protocol transceivers from 250 Mbps to 12.7 Gbps Up to 461k logic elements consisting of a 4-input Look-Up Table (LUT) with a fracture-able D-type flip-flop Up to 31.6 Mb of RAM Power optimized transceivers Up to 1420 18 × 18 multiply-accumulate blocks with hardened pre-adders Integrated dual PCIe for up to ×4 Gen 2 Endpoint […]

Qualcomm Snapdragon 7c & 8c Processors Target Entry-Level & Mainstream Mobile PCs

Nearly exactly one year ago, Qualcomm announced the Snapdragon 8cx processor for always-on always-connected PCs, and lateron Qualcomm and UL released PCMark 10 benchmark results showing Snapdragon 8cx had similar performance to a 15W Intel Core i5-8250U Kaby Lake-R processor, but with much better efficiency. The price of such laptops is still fairly high with Samsung Galaxy Book S announced in August for $1,000, and possibly canceled at this stage. Microsoft SQ1 powered Surface Pro X tablet is the only system based on Qualcomm Arm technology (customized version of Snapdragon 8cx) available now, and also sells for $1,000 and up. Qualcomm has now unveiled Snapdragon 7c and 8c arm processor to address the entry-level and mainstream markets of connected mobile PCs. Qualcomm Snapdragon 7c Specifications: CPU – Octa-core Kryo 468 processor @ up to 2.45 GHz GPU – Qualcomm Adreno 618 GPU DSP – Qualcomm Hexagon 692 DSP with Hexagon […]

webOS OSE 2.0 Adds Support for Rapsberry Pi 4, Dual Displays, FOTA and More

Back in March 2018, LG unveiled webOS Open Source Edition optimized for Raspberry Pi 3 board. Last month, the company released a major version with webOS OSE 2.0 adding support for Raspberry Pi 4, dual displays, FOTA support and more. We missed the release at the time but caught up as LG just released a minor update with webOS OSE 2.1 a few days ago that adds a Japanese keyboard, uses journald, and provides various fixes and improvements. Some of the new features of webOS OSE 2.x include: Dual-display support which will eventually enable multi-display support for rear-seat entertainment (RSE) systems Firmware-Over-the Air (FOTA) Smack integration for enhanced security New passenger-friendly and touch input optimized Home Launcher as shown above WiFi tethering support via SoftAP Added support Raspberry Pi 4 (new reference hardware) Upgrade to Qt 5.12 and Chromium 72 webOS is generally known as an operating system for televisions, […]

PiPo Snapdragon 850 2-in-1 Laptop to Sell for around $400

Current Qualcomm based Windows 10 laptops are mostly interesting for people wanting all-day battery life and/or being always connected over 4G LTE, as they are still pretty expensive, and performance somewhat underwhelming, although Snapdragon 8cx processor should change that.
