Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.17 changelog

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]

Linux 5.15 LTS release – Main Changes, Arm, RISC-V and MIPS architectures

Linux 5.15

Linus Torvalds released Linux 5.15, an LTS version, this past Sunday: It’s been calm, and I have no excuse to add an extra rc, so here we are, with v5.15 pushed out, and the merge window starting tomorrow. Which is going to be a bit inconvenient for me, since I also have some conference travel coming up. But it’s only a couple of days and I’ll have my laptop with me. Sometimes the release timing works out, and sometimes it doesn’t.. Anyway, the last week of 5.15 was mainly networking and gpu fixes, with some random sprinkling of other things (a few btrfs reverts, some kvm updates, minor other fixes here and there – a few architecture fixes, couple of tracing, small driver fixes etc). Full shortlog appended. This release may have started out with some -Werror pain, but it calmed down fairly quickly and on the whole 5.15 was […]

Jupiter Nano – Tiny Cortex-A5 board runs Linux or NuttX RTOS (Crowdfunding)

Jupiter Nano

Jupiter Nano looks like one of those small MCU boards, but instead of a microcontroller, it packs a 500 MHz Microchip SAMA5 Cortex-A5 processor with 128MB RAM capable of running Linux or NuttX operating systems. The board reminds me of the Adafruit Feather compatible Giant Board made by Groboards, with the same system-in-package, but Juniper Nano offers more I/Os via 48 through holes, and its size is said to be similar to Teensy 4.1 board (but not quite). Jupiter Nano specifications: SiP – Microchip SAMA5D27C-LD1G with Cortex-A5 processor running at 498 MHz, 128MB LPDDR2 DRAM Storage – MicroSD card socket (bootable) USB – 1x Micro USB 2.0 host/device port, 1x USB 2.0 host on header Expansion – 2x 24-pin headers with GPIOs, USB, SPI, I2C, up to 4x Flexcom interfaces configurable as SPI, UART or I2C Programming – JTAG port, Micro USB 2.0 FS debug console via MCP2200 USB-UART converter […]

HaneSOM is a 4 cm2 Arm Linux module powered by Microchip SAMA5D2 SiP

HaneSOM

DAB Embedded HaneSOM is a tiny (4 cm2) system-on-module based on Microchip SAMA5D2 Arm Cortex-A5 processor running Linux, which could make it the world’s smallest Linux module. The small size is made possible by the use of a SAMA5D2 system-in-package that also integrates 128MB DDR2, and the only two other chips on the modules are a 4MB flash (GD25Q32) and the PMIC (MIC2800). HaneSOM specifications: SiP – Microchip ATSAMA5D27C-D1G system-in-package with SAMA5D27 Arm Cortex-A5 processor @ 500 MHz with NEON, 128MBytes DDR2 System Memory – 128MBytes DDR2 memory Storage – 4 MBytes of QSPI Flash Castellated holes giving access to signal for: Storage – SD card interface Display – 24-bit RGB LCD TFT interface; capacitive touch controller Camera – Up to 5MP CMOS camera sensor support Audio – SSC, I2S Networking – 10/100M Ethernet USB – USB 2.0 (OTG and host) SPI, I2C, UART, CAN-FD, 12-bit ADC, PWM Misc – […]

Arrow Embedded To Go Free Online Conference, and 3,000 Development Boards Giveaway

Arrow Embedded to Go

With the coronavirus outbreak on-going, many events are either canceled or moving online. Arrow Electronics has now announced what appears to be a completely new online event. Embedded To Go virtual technology exhibition for embedded systems will take place on April 1-3, 2020, and offer technical presentations, information on newly launched technology, and access to Arrow’s sales and engineering teams. The event will entirely free to attend, and you can register online today with a company’s email address. The event will start in about 10 days by so far the virtual “booth map”, “supplier guide” and “lecture area” are inaccessible. We only know what the event should consist of thanks to an article on EENew Embedded: Technical presentation webinars will be hosted by leading suppliers covering AI, IoT and Edge computing, precision measurement, high-performance computing, intelligent condition-based monitoring, and other technological subjects. Information will also be available in the form […]

Arrow Shield96 Arm Linux Board Focuses on Hardware-based Security

Arrow Shield96

Powered by a Microchip SAMA5D2 SiP integrating a Cortex-A5 processor and 128MB DDR2 memory, Arrow Shield96 board has been designed for secure IoT application development with on-board hardware security. Two versions of the SBC are offered: Shield96 Standard reference platform Shield96 Trusted Platform preloaded with the EmSPARK Security Suite software by Sequitur Labs. Both versions come with the same hardware specifications: SiP – Microchip ATSAMA5D27-D1G Arm Cortex-A5 processor @ 500 MHz with 128MB DDR2 Storage – 128MB DDR2 Storage – 128MB (1Gbit) flash, MicroSD card slot Connectivity – 10/100M Ethernet port, 2.4 GHz 802.11b/g/n WiFi 4 via ATWILC1000 “IoT link controller module” USB – 1x USB 2.0 port HW Security – ATECC608 secure element Expansion – 96Boards Mezzanine connector Debugging – JTAG header, serial console via Micro USB port Power Supply – 5V via Micro USB port Dimensions – N/A (CNXSoft note: it’s supposed to be 96Boards compliant, but with […]

Marlin 2.0 Open Source 3D Printer Firmware Finally Released

Marlin 2.0 Firmware Release

Back in June, we wrote about Marlin 2.0 firmware supporting ESP32 3D printer board, but at the time the firmware was still in RC1 (Release Candidate) phase. I was informed Marlin 2.0 firmware had been in beta for several years now, but the good news is that Marlin 2.0.0 open-source 3D printer firmware has now been officially released. Some of Marlin 2.0.0 new features include: 32-bit support with several boards including Arduino DUE (SAM3X8E), Adafruit Grand Central (SAM5D), Smoothie / SBASE / EZBoard based on NXP LPC176x, SKR Mini powered by STM32, as well as ESP32 boards Some improvements were made to some AVR boards including Melzi (ATmega 1280), RAMPS (ATmega 2560), and RAMBo / miniRAMBo / Einsy RAMBo boards PlatformIO build environments for supported boards VSCode “Auto Build Marlin” extension for one-click build Power-Loss Recovery for SD print jobs Magnetic Parking Extruder support Magnetic Switching Toolhead and Toolchanger support […]

Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white.  Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast.  There was an in-depth article written on a similar hub some time ago.  Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is […]
