RAUC open-source OTA update solution enabling A/B updates for embedded Linux images has recently been ported to the Radxa Rock Pi 4 Model B SBC powered by a Rockchip OP1 SoC by the project’s maintainer, Leon Anavi working for Konsulto Group. If you run a Linux distribution like Ubuntu, Debian, or Fedora, packages and OS images are taken care of automatically or by running a few commands. However, software engineers who build custom embedded Linux images with the Yocto Project or Buildroot must handle this themselves. Luckily, there are already open-source OTA firmware update solutions such as Mender, Balena, Torizon, OSTree, Snap, or RAUC, and we’ll look at the latter today. RAUC (Robust Auto-Update Controller) was started by Pengutronix in 2015 and eventually adopted by the community. It’s a lightweight update client that runs on an Embedded Linux device and controls the A/B update procedure when a new firmware revision […]
Sipeed Tang Mega 138K Dock is a lower-cost GOWIN GW5AST FPGA + RISC-V development board
The Sipeed Tang Mega 138K Dock is a low-cost version of the Tang Mega 138K Pro development board launched last year with the GOWIN GW5AST FPGA + RISC-V SoC, two SPF+ cages, a PCIe 3.0 x4 interface, and DVI Rx and Tx ports. The new Tang Mega 138K Dock keeps a GW5AST FPGA SoC but with a 484-ball package that fits on a smaller system-on-module, and does without the SPF+ cages, replaces the PCIe 3.0 x4 interface with a PCIe 2.0 x4 interface, and only uses a single HDMI port for DVI Rx or Tx. Sipeed Tang Mega 138K system-on-module Let’s first have a look at the specifications of the SoM itself: SoC FPGA – GOWIN GW5AST-LV138FPG484A with 138,240 LUT4 1,080 Kb Shadow SRAM (SSRAM) 6,120 Kb Block SRAM (BSRAM) Number of BSRAM – 340 298x DSP slices 12x PLLs 16x global clocks 24x HCLK 8x transceivers at 270Mbps to […]

Zigbee Coordinator CC2652P7 1.0 runs open-source firmware, works with Zigbee2MQTT, Home Assistant, and ioBroker
The cod.m Zigbee Coordinator 1.0 (CZC 1.0) is a hybrid ZigBee coordinator that can be used to connect devices over a network (Ethernet/Wi-Fi) and USB. The ZigBee Coordinator version 1.0 is an upgrade of version 0.2 released in 2022. The CZC 1.0 replaces the Texas Instruments CC2652P2 chip with the much more powerful CC2652P7 chip, uses an ESP32-WROOM-32E module instead of the USR-K6 chip, and adds compatibility with Home Assistant (ZHA integration). It can create a Zigbee network and pair Zigbee devices over Ethernet, WiFi, or Serial (USB). It features the same Texas Instruments CC2652P7 chip as the SMLIGHT line of Zigbee Ethernet/WiFi/USB coordinators and USB dongles. There are two models of the CZC 1.0: a Power over Ethernet model and a model that can only be powered via USB-C. cod.m Zigbee Coordinator specifications: Zigbee SoC – Texas Instruments CC2652P7 Arm Cortex-M4F microcontroller @ 48 MHz with 704 KB flash, […]
HIGOLE F9B Pro Intel N100 mini computer comes with a built-in 7-inch touchscreen display and 5,000 mAh battery
HIGOLE F9B Pro is a mini PC powered by an Intel Processor N100 quad-core CPU and equipped with a built-in 7-inch touchscreen display, a 5,000mAh battery, and full-size ports that could be confused with a 7-inch tablet if it was not so thick… GOLE/HIGOLE has made many such mini PCs with integrated displays over the years initially to lower the Windows license fee, but they’ve kept making those with new Intel families, for example with the Gemini Lake-powered GOLE1 Pro mini PC with a 5.5-inch display introduced in 2022.

NUMA emulation patch boosts Geekbench 6 benchmark results by up to 18% on Raspberry Pi 5
Igalia Engineer, Tvrtko Ursulin has recently submitted a patch to the Linux kernel adding a NUMA (Non-Uniform Memory Access) emulation implementation for arm64 platforms that boosts the performance of 64-bit Arm targets by “splitting the physical RAM into chunks and utilizing an allocation policy to better utilize parallelism in physical memory chip organization”.
The NUMA emulation implementation was tested on a Raspberry Pi 5 SBC and the Geekbench 6 single-core score improved by 6%, while the multi-core score boosted by 18% after splitting into four emulated NUMA nodes. In other words, that’s like having a Broadcom BCM2712 CPU overclocked from 2.4 GHz up to 2.83 GHz.
