ODYSSEY-X86J4125 SBC gets a faster Celeron J4125 SoC and a price increase

ODYSSEY-X86J4105 is an Intel Gemini Lake SBC designed for makers with Arduino compatibility thanks to a Microchip SAMD21 microcontroller, as well as Raspberry Pi headers. We reviewed the board and enclosure last year both with Windows 10 Enterprise and Ubuntu 20.04, and we also successfully tested the Arduino and Raspberry Pi GPIO headers with the latter. But the Intel Celeron J4105 quad-core Gemini Lake processor has been scheduled for discontinuance since last year, and the last order on January 22, 2021, and the final shipment on planned for July 9, 2021. So Seeed Studio had to find a replacement, and they’ve now launched ODYSSEY-X86J4125 single board computer with the same features, but switching to a slightly faster, and still available, Intel Celeron J4125 processor. ODYSSEY-X86J4125800 SBC specifications: SoC – Intel Celeron J4125 quad-core Gemini Lake Refresh processor @ 2.0 / 2.7 GHz (Turbo) / 2.4 GHz (Turbo all cores) with Intel UHD Graphics 600 @ 250/750 MHz; 10W TDP System […]

InfiniTime 1.0 firmware released for PineTime smartwatch

The PineTime smartwatch was unveiled and first launched in 2019, as a low-cost, open-source wearables development kit/platform for developers wanting to work on firmware development for the Nordic nRF52 powered device. Progress was made on various solutions such as ATCwatch Arduino firmware, and as time passed, the PineTime slowly became more like an “enthusiast-grade” end-user product. This is basically what it has become with the first stable release of InfiniTime firmware, which was selected as the default firmware in September 2020. The main features of InfiniTime 1.0 firmware include: Two clock faces – digital and analog Apps – Stopwatch, music control, navigation, heart rate, as well as Paddle and 2048 games User settings – Display timeout, time format, wake up conditions OTA upgrades via an open-source bootloader based on MCUBoot Heart rate monitoring and step counting Between 3 and 5 days of battery life depending on usage Firmware based on FreeRTOS 10.0.0 real-time OS, LittleVGL/LVGL 7 graphics library, and NimBLE […]

Samsung Galaxy Upcycling at Home program aims to repurpose older phones into IoT devices

Electronics waste, also as known as e-waste, has been a problem talked about for years, and in 2015 we asked the question “What do you do with your old devices and boards?” as many devices just end up collecting dust or stored in a drawer. Some better ways include giving or selling them to others, or repurpose them. For instance, a cheap Arm HDMI dongle can make a torrent downloader, an old phone can be transformed into a surveillance camera, an ATX power supply could be converted into a bench power supply, etc… But repurposing devices require some technical skills which many of the smart CNX Software readers have, but it’s unrealistic to expect the typical consumer to be able to hack their old devices into new ones using some tutorials found on the Internet. Samsung Galaxy Upcycling Program aims to make recycling upcycling easier for owners of Galaxy smartphones, and allows them to use the phones as baby monitors, […]

PhD students willfully committed known malicious changes to mainline Linux

We just reported about the Linux 5.12 changelog with a focus on Arm, MIPS and RISC-V targets on Tuesday, and at the time, the expectation was a delay of about one week after Linux 5.12-rc8 was outed on Sunday, April 18. But Linux 5.12 could be further delayed due to shenanigans from two Ph.D. students doing a research project on open-source vulnerability at the University of Minnesota. This was announced by Greg Kroah-Hartman on the Linux kernel mailing list. Commits from @umn.edu addresses have been found to be submitted in “bad faith” to try to test the kernel community’s ability to review “known malicious” changes. The result of these submissions can be found in a paper published at the 42nd IEEE Symposium on Security and Privacy entitled, “Open Source Insecurity: Stealthily Introducing Vulnerabilities via Hypocrite Commits” So their work at to be reverted with 190 reversions so far. It also means future commits from the University of Minnesota will be […]

Business card-sized dual GbE SBC runs OpenWrt on Rockchip RK3328 SoC

We’ve previously reported about at least two dual GbE router boards based on Rockchip RK3328 quad-core Cortex-A53 processor with namely NanoPi R2S and Orange Pi R1 Plus. But there’s now a third option with SmartHomeBoard Pi-R2S3328-B single board computer offered in a larger business card-sized format, equipped with 1GB DDR4, and booting OpenWrt from a MicroSD card. Debian and Ubuntu are also supported according to the manufacturer. Specifications: SoC – Rockchip RK3328 quad-core Cortex-A53 @ 1.5 GHz with Arm Mali-450MP2 System Memory – 1GB DDR4 RAM (Note some photos how 2x 512MB DDR3 instead) Storage – MicroSD Slot Connectivity -2x Gigabit Ethernet RJ45 ports, one native, one USB 3.0 to GbE USB – 1x USB Type-A host port, 1x micro USB OTG port, 1x USB Type-C port for power Debugging – 3-pin 2.54mm pitch header for serial console Misc – Reset button, Sys,WAN and LAN LED’s, Power Supply – 5V/2A via USB-C port Dimensions – 85 x 56 mm Weight […]

Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend. Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a subsystem that allows the power usage of groups of devices […]
