Linux 4.17 Release – Main Changes, Arm & MIPS Architectures

Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch […]

Xiaomi Mi Router 4 is a $60 AC1200 Router with Three Gigabit Ethernet Ports

Xiaomi Mi Router 3 AC1200 router based on Mediatek MT7620A processor was launched in 2016 for just under $40 on online retailers. It had at least one caveat however, since it only supported Fast Ethernet. The company has now launched an upgraded version – Xiaomi Mi Router 4 -, still an AC1200 router, but equipped with a faster Mediatek MT7621A processor, and three Gigabit Ethernet ports. The new router sells for 199 RMB ($31 US) in China, but it’s also found for under $60 including international shipping on sites like Banggood or GearBest. Mi Router 4 (Miwifi 4) specifications: WiSoC – Mediatek MT7621A dual core MIPS processor @ 880MHz System Memory – 128 MB DDR3-1200 Storage – 128 MB SLC NAND Flash Wi-Fi 2.4GHz – 2X2 MIMO up to 300Mbps 5GHz – 2X2 MIMO up to 867 Mbps Wireless Security – WPA-PSK/WPA2-PSK encryption, wireless access control (black and white list), […]

RAK833 is an Industrial Grade mini PCIe LoRaWAN Gateway Card

The most obvious way to setup your own LoRAWAN network is to get an off-the-shelf Gateway such as MatchBox, which can be easily installed, and configured using the built-in web interface. But if you need something more flexible, Rakwireless RAK833 could be an interesting option, as an industrial grade LoRaWAN gateway that you can just insert into an advanced router or computer’s mini PCIe slot. RAK833 card specifications: LoRa Connectivity Semtech SX1301 Digital Baseband Chip for outdoor LoRaWAN macro gateways 2x Semtech SX1255/7 Tx/Rx front-end 49x LoRa demodulators, 10 parallel demodulation paths Frequencies – 433 MHz, 470 MHz, 868 MHz, and 915 MHz Tx Power – Up to 25 dBm Rx Sensitivity – -140 dBm Host Interface – 52-pin mPCIe edge connector with USB and SPI (via FT2232H) signals; Supply Voltage – 3.3V compatible with 3G/LTE mPCIe cards Dimensions – 50.95 x 30 mm The card ships with an external […]

MT3620 Development Board for Azure Sphere is Up for Pre-order for $84.90

Microsoft unveiled Azure Sphere solutions last month in order to provide a complete secure IoT solution from the hardware to the cloud with three main components: a secure MCU, Linux based Azure Sphere OS, and Azure Sphere Security (Cloud) Service. The company already stated Mediatek MT3620 would be the first Azure Sphere compliant MCU, and today Seeed Studio has announced MT3620 development board for Azure Sphere is up for pre-order for $84.90 with a $5 deposit, and shipping scheduled for the end of September. Preliminary specifications of MT3620 development board for Azure Sphere: WiSoC – Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz, dual core Arm Cortex-M4F real-time core, Pluton security sub-system, and WiFi. System Memory – Over 5MB of embedded RAM, split among the various cores (4MB for Arm Cortex A7 core) Storage – 2x 8MB dual channel quad SPI (16MB in total) Connectivity – Dual band […]

Ubiquiti EdgeRouter X is a $60 Gigabit Ethernet PoE Router Supported by OpenWrt

Stanislav needed a Gigabit Ethernet router to run OpenVPN, and after some research he settled on Ubiquiti EdgeRouter X router with 5 Gigabit Ethernet ports, PoE in and pass-through, with a decent 256 MB RAM and 256MB flash, and a $49 MSRP, although I’ve only seen it for $60 and up. The router is not a new product, as it has been out for a few years (since 2015), and it’s also officially supported by OpenWrt, which makes it even more interesting. Ubiquiti EdgeRouter X (ER-X model) specifications: Processor – Mediatek MT7621AT dual core MIPS1004Kc processor @ 880 MHz System Memory – 256MB RAM Storage – 256 MB NAND flash for firmware 5x Gigabit RJ45 ports Ports configurable for line-rate, Layer-2 switching 260 kpps for 64-byte packets 1 Gbps for 1518-byte packets Passive PoE passthrough option Power – 24V via passive PoE or power adapter There’s also a ER-X-SFP model […]

My Experience with Dodocool AC750 WiFi Repeater

A while ago, I tested Dodocool DC30S USB type C Hub with HDMI, USB port, and a card reader, and recently the company asked me whether I wanted to review another of their accessories. My ISP has recently taken the habit of being down several hours each month, so I rely on my neighbor’s WiFi (with he’s permission) in those case, but since the signal is too weak, I’m using a wireless audio streamer and a power bank to extend the signal and connect it to my router using WDS Bridging. Then I saw Dodocool DC24 802.11ac WiFi repeater, so I decided to give it a chance. Dodocool DC24 A750 Repeater Unboxing I received the device is a cardboard box with some specifications. It’s an AC750 router/repeater with 300 Mbps @ 2.4 GHz + 433 Mbps @ 5 GHz. The product page linked above has some more details with the […]

Microsoft Introduces Azure Sphere OS Linux Operating System for Certified Microcontrollers (MediaTek MT3620 for now)

Last year, Microsoft announced they were working with Mediatek on Project Sopris Secure WiFi MCU, based on Mediatek MT7687 MIPS microcontroller with 7 properties enhancing security (Hardware-based Root of Trust, failure reporting etc…). The company has now unveiled a complete secure IoT solution with Azure Sphere comprised of three main components: Azure Sphere certified secured MCUs which combine real-time and application cores with built-in Microsoft security technology and connectivity. The first compatible MCU will be Mediatek MT3620, which differs from MIPS based Project Sopris, as it features one Cortex A7 and two Cortex M4 cores as well as WiFi connectivity. Azure Sphere OS that provides four layers on top of the hardware: security monitor, custom Linux kernel, on-chip connectivity services to Azure Sphere Security Service, and app containers for computer (A7 core) or/and real-time I/Os (M4 cores). Azure Sphere Security Service, a secure cloud service for Azure Sphere device that […]

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is […]
