QEMU 9.0 released with Raspberry Pi 4 support and LoongArch KVM acceleration

QEMU 9.0 open-source emulator just came out the other day, and it brings on board major updates and improvements to Arm, RISC-V, HPPA, LoongArch, and s390x emulation. But the most notable updates are in Arm and LoongArch emulation. The QEMU 9.0 emulator now supports the Raspberry Pi 4 Model B, meaning you can run the 64-bit Raspberry Pi OS for testing applications without owning the hardware. However, QEMU 9.0 has some limitations since Ethernet and PCIe are not supported for the Raspberry Pi board. According to the developers, these features will come on board in a future release. For now, the emulator supports SPI and I2C (BSC) controllers. Still on ARM, QEMU 9.0 provides board support for the mp3-an536 (MPS3 dev board + AN536 firmware) and B-L475E-IOT01A IoT node, plus architectural feature support for Nested Virtualization, Enhanced Counter Virtualization, and Enhanced Nested Virtualization. If you develop applications for the LoongArch […]

NanoCell V2.1 battery-powered ESP32-C3 IoT board runs ESPHome for Home Assistant integration

The NanoCell V2.1 is a development board built around the Espressif ESP32-C3 SoC (system-on-a-chip) preloaded with ESPHome firmware for low-power applications and improved Lithium battery management. The development board is a white printed circuit board with gold-plated contacts and a battery fuel-gauge IC, designed by Frapais’ lab in Greece. As the name suggests, the NanoCell V2.1 is the latest in a series of iterations of ESP32-C3-based devices targeted at low-power applications. Compared to earlier versions, it offers a better user experience and improved power efficiency. It features a buck-boost converter that reduces standby current consumption to 66uA (excluding the current consumed by the ESP32 module). The battery management system (BMS) integrated circuit supports accurate capacity measurement and protects connected Lithium batteries from overcharging and other harmful scenarios. Also, two LEDs on the board serve as power and charging indicators to relay the board’s status. It is based on the same […]

Loongson 2K1000LA dual-core LoongArch processor powers industrial SBCs and IoT gateways

Loongson 2K1000LA is a 1GHz dual-core 64-bit LoongArch processor designed for industrial applications with gigabit Ethernet, SATA, two PCIe interfaces, two digital video outputs, audio interfaces, USB 2.0, and others all in a 1 to 5W power envelop. It is found in Loongson’s own development board and Banana Pi BPI-5020 2K1000LA SBC. The LoongArch architecture was first introduced in 2021 as an alternative to Arm, x86, and RISC-V, and heavily inspired by MIPS with extra instructions.  Some of the first LoongArch processors were the Loongson 3A5000 and 3C5000 SoCs for desktop computers and servers respectively, and now, the company has launched a lower-power processor for industrial applications, such as IoT gateways, with the 2K1000LA. Loongson 2K1000LA specifications We only have some basic specifications from the product page on Loongson’s website.; CPU – 2x 64-bit LoongArch cores clocked at 1GHz FPU – 128-bit vector unit Cache 32KB L1 instruction cache 32KB […]

WeAct ESP32-C6-Mini is the cheapest ESP32-C6 board so far going for less than $4

WeAct ESP32-C6-Mini is a small development board based on Espressif Systems ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless SoC that’s the cheapest we’ve seen so far selling for just $3.86 on Aliexpress. WeAct was one of the first companies to launch a third-party ESP32-C6 development board year with the price starting at just $6. I still remember the excitement around the first $5 ESP8266 WiFi 4 module when we first covered it in 2014, and ten years later, we can get a full $4 development board with a more powerful 160 MHz RISC-V microcontroller, WiFi 6, Bluetooth 5.0, and an 802.15.4 radio for Thread, Zigbee, and Matter. WeAct ESP32-C6-Mini specifications: Wireless SoC – ESP32-C6-N4 CPU Single-core 32-bit RISC-V clocked up to 160 MHz Low-power RISC-V core @ up to 20 MHz Memory – 512KB SRAM, 16KB low power SRAM Storage – 320KB ROM, and 4MB flash Wireless – 2.4 GHz […]

Yocto Project 5.0 “Scarthgap” released with Linux 6.6 and plenty of changes

The Yocto Project 5.0 codenamed “Scarthgap” has just been released with Linux 6.6, glibc 2.39, LLVM 18.1, and over 300 other recipe upgrades. As a result of the release, the developers have made it available for download (bz2 tarball). The Yocto Project, or Yocto for shorts, is a popular framework used to create custom embedded Linux distributions, and we’ve played with it over the year showing how to create a minimal image for the Raspberry Pi, and last year, we used it again when reviewing two industrial development boards, namely the VOIPAC IMX8M and ADLINK i-Pi SMARC 1200. Yocto is quite a powerful framework/build system with plenty of options that make it highly customizable, but the learning curve is fairly steep. Some other changes in Yocto Project 5.0 include: New variables: CVE_DB_INCR_UPDATE_AGE_THRES: Configure the maximum age of the internal CVE database for incremental update (instead of a full redownload). RPMBUILD_EXTRA_PARAMS: […]

SBC Case Builder v3.0 can create thousands of cases for popular SBCs and standard motherboards (mini-ITX, Pico-ITX, NUC…)

SBC Case Builder V3.0 case design utility has just been released with the ability to create over 1,000 standard cases – not including customization – for popular SBCs from Raspberry Pi, Hardkernel, Orange Pi, Radxa, and others, as well as standard motherboards following Mini-ITX, Pico-ITX, NUC, Nano-ITX, etc.., and SBC adapters following these standards, meaning you could install a Raspberry Pi 5 into a mini-ITX case if needed. SBC Case Builder started as a command line utility for designing DIY case for SBCs relying on OpenSDAD in April 2022, but Edward Kisiel (hominoids) quickly released version 2 with a GUI in October or the same, and has now further improved the utility with the release of SBC Case Builder v3.0. Version 3.0 comes with many improvements but the main focus was to reuse existing and new PC standard form factor cases by creating SBC adapters and custom I/O Shields since […]

Ubuntu 24.04 LTS “Noble Numbat” released with Linux 6.8, up to 12 years of support

Canonical has just released Ubuntu 24.04 LTS “Noble Numbat” distribution a little over two years after Ubuntu 22.04 LTS “Jammy Jellyfish” was released. The new version of the operating system comes with the recent Linux 6.8 kernel, GNOME 46, and a range of updates and new features we’ll discuss in this post. As a long-term support release, Ubuntu 24.04 LTS gets a 12-year commitment for security maintenance and support, with five years of free security maintenance on the main Ubuntu repository, and Ubuntu Pro extending that commitment to 10 years on both the main and universe repositories (also free for individuals and small companies with up to 5 devices). This can be extended a further 2-year, or 12 years in total, for Ubuntu Pro subscribers who purchase the Legacy Support add-on. Canonical explains the Linux 6.8 kernel brings improved syscall performance, nested KVM support on ppc64el, and access to the […]

Industrial MicroATX motherboards support Intel Core 12th-14th Gen processors with up to four 2.5GbE/10GbE ports

DFI has recently unveiled two new Industrial MicroATX Motherboards, the RPS310 and ADS310, that claim to have support for Core 12th Gen (Alder Lake-S), 13th Gen (Raptor Lake-S), and 14th Gen (Raptor Lake-S Refresh) processors. The motherboards can be built around R680E or Q670E chipset and support a range of peripherals including VGA, DP++, HDMI, PCIe, M.2 M key, SATA3.0, and much more. The key difference between the two is that the RPS310 supports DDR5 memory, features 4x Intel 2.5GbE network connections, and has a 10-year CPU lifecycle with optional 5-year extended support. In contrast, the ADS310 supports DDR4 memory, features 2x Intel 10GbE + 2x Intel 2.5GbE network connections, and boasts a longer 15-year CPU lifecycle support. We’ve previously covered motherboards with a similar form factor, including the HiFive Pro P550 and Milk-V Pioneer, both powered by RISC-V CPUs. If you’re interested in alternative architectures, you might also enjoy […]
