Linux 6.0 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.0 Release

Linux 6.0 has just been released by Linus Torvalds: So, as is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes. But of course there’s a lot of various changes in 6.0 – we’ve got over 15k non-merge commits in there in total, after all, and as such 6.0 is one of the bigger releases at least in numbers of commits in a while. The shortlog of changes below is only the last week since 6.0-rc7. A little bit of everything, although the diffstat is dominated by drm (mostly amd new chip support) and networking drivers. And this obviously means that tomorrow I’ll open the merge window for 6.1. Which – unlike 6.0 – has a number of fairly core new things lined up. But for now, please do give this most […]

Orange Pi 800 Keyboard PC – A Raspberry Pi 400 alternative powered by Rockchip RK3399

Raspberry Pi 400 Keyboard PC alternative

There’s now a Raspberry Pi 400 alternative with the Orange Pi 800 Keyboard PC that offers a very similar design, but it is powered by a Rockchip RK3399 hexa-core Cortex-A72/A53 processor. Like the Raspberry Pi model, the Orange Pi 800 comes with 4GB RAM, Gigabit Ethernet, dual-band WiFi 5 and Bluetooth 5.0, two USB 3.0 ports, and one USB 2.0 port, but it also adds 64GB on-board flash storage and features one full-size HDMI port capable of 4Kp60 resolution plus a VGA port, instead of two micro HDMI ports. Orange Pi 800 specifications: SoC – Rockchip RK3399 hexa-core big.LITTLE processor with 2x Arm Cortex-A72 cores up to 1.8GHz, 4x Arm Cortex-A53 cores up to 1.4GHz, and an Arm Mali-T860MP4 GPU System Memory – 4GB LPDDR4 Storage – 64GB eMMC flash, microSD card slot Video Output HDMI 2.0 port up to 4Kp60 VGA port up to Full HD resolution Audio 3.5mm […]

Sipeed MetaSense RGB ToF 3D depth cameras are made for MCUs & ROS Robots (Crowfunding)

Sipeed MetaSense RGB ToF 3D Depth Cameras

We’ve just written about the Arducam ToF camera to add depth sensing to Raspberry Pi, but there are now more choices, as Sipeed has just introduced its MetaSense ToF (Time-of-Flight) camera family for microcontrollers and robots running ROS with two models offering different sets of features and capabilities. The MetaSense A075V USB camera offers 320×240 depth resolution plus an extra RGB sensor, an IMU unit, and a CPU with built-in NPU that makes it ideal for ROS 1/2 robots, while the lower-end MetaSense A010 ToF camera offers up to 100×100 resolution, integrates a 1.14-inch LCD display to visualize depth data in real-time and can be connected to a microcontroller host, or even a Raspberry Pi, through UART or USB. MetaSense A075V specifications: SoC – Unnamed quad-core Arm Cortex-A7 processor @ 1.5 GHz with 0.4 TOPS NPU System Memory – 128 MB RAM Storage – 128MB flash Cameras 800×600 @ 30 […]

TinyMaix is a lightweight machine learning library for microcontrollers

TinyMaix machine learning Arduino

Sipeed TinyMaix open-source machine learning library is designed for microcontrollers, and lightweight enough to run on a Microchip ATmega328 MCU found in the Arduino UNO board and its many clones. Developed during a weekend hackathon, the core code of TinyMax is about 400 lines long, with a binary size of about 3KB, and low RAM usage, enabling it to run the MNIST handwritten digit classification on an ATmega320 MCU with just 2KB SRAM and 32KB flash. TinyMax highlights Small footprint Core code is less than 400 lines (tm_layers.c+tm_model.c+arch_O0.h), code .text section less than 3KB Low RAM consumption, with the MNIST classification running on less than 1KB RAM Support INT8/FP32 model, convert from keras h5 or tflite. Support multi-architecture acceleration: ARM SIMD/NEON, MVEI, RV32P, RV64V (32-bit & 64-bit RISC-V vector extensions) User-friendly interfaces, just load/run models Supports full static memory config MaixHub Online Model Training support coming soon Sipeed says there […]

BITBLAZE Titan BM15 Arm Linux laptop features Baikal-M1 processor

BITBLAZE Titan BM15 Baikal M1 laptop

Russian company Prombit has unveiled the BITBLAZE Titan BM15 Arm Linux Laptop equipped with Baikal-M1 octa-core Arm Cortex-A57 processor manufactured by TSMC, up to 128GB RAM, SSD storage, and a 15.6-inch Full HD display. Baikal-M1, also called Baikal-M, was already found in desktop PCs and All-in-One Arm Linux computers launched last year for the Russian government and businesses, but I think it’s the first time it shows up in a laptop. BITBLAZE Titan BM15 specifications: SoC – Baikal M1 ((BE-M1000) octa-core Cortex-A57 processor @ up to 1.5 GHz with Arm Mali-T628 GPU; 28nm manufacturing process System Memory – 16GB RAM, upgradeable up to 128 GB thanks to the two SO-DIMM DDR4 sockets [Update: Our previous article about Baikal M1 only showed the processor to support up to 32GB RAM, and 64GB DDR4 SO-DIMM modules don’t seem to exist, so the 128GB claim appears to be an error] Storage – 250 […]

Linux 5.19 Release – Main changes, Arm, RISC-V and MIPS architectures

Linux 5.19 release arm risc-v mips

Linus Torvalds has just announced the release of Linux 5.19. It should be the last 5.xx version, with Linux 6.0 coming for the next cycle: So here we are, one week late, and 5.19 is tagged and pushed out. The full shortlog (just from rc8, obviously not all of 5.19) is below, but I can happily report that there is nothing really interesting in there. A lot of random small stuff. In the diffstat, the loongarch updates stand out, as does another batch of the networking sysctl READ_ONCE() annotations to make some of the data race checker code happy. Other than that it’s really just a mixed bag of various odds and ends. On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, […]

XRF16 Gen3 SOM features Xilinx Zynq UltraScale+ ZU49DR RFSoC with up to 6GHz bandwidth

Avnet XRF16 Xilinx RFSoC Gen3 SOM

We’ve written about Xilinx Zynq UltraScale+ MPSoCs that combine Arm Cortex-A53/R5 cores and Mali-400 GPU with Ultrascale FPGA fabric several times over the course of a few years. But AMD-Xilinx also offers the Zynq UltraScale+ RFSoC single-chip adaptable radio platforms that support up to 7.125GHz analog bandwidth. The topic came to my attention because of an upcoming ZU49DR SoM from iWave Systems that seems to be under development but also noticed Avnet had launched a solution last year with the XRF16 Gen3 SoM featuring the same third-generation Zynq Ultrascale+ ZU49DR RFSoC with 16 RF-ADC, 16 RF-DAC channels, and 6GHz RF bandwidth. Avnet XRF16 specifications: Main chip – Xilinx Zynq UltraScale+ Gen3 ZU49DR RFSoC with Quad-core Arm Cortex-A53 processing subsystem Dual-core Arm Cortex-R5F MPCore up to 533MHz 16x ADCs, 14-bit up to 2.5 GSPS 16x DACs, 14-bit up to 9.85 GSPS (10 GSPS Available) 1 GbE, PCIe Gen1/2, SATA, USB2/3 UltraScale+ […]
