BredOS Arch Linux Arm distribution runs on Rockchip RK3588 single board computers

BredOS is a Linux distribution based on Arch Linux Arm and optimized to run on Rockchip RK3588/RK3588S single board computers (SBCs) with current support for 22 boards from Radxa, Orange Pi, Khadas, and others. Board vendors will usually provide OS images for their SBCs, but the quality and support may be limited, so projects like Armbian and DietPi are maintaining Ubuntu and/or Debian images for popular single board computers. But if you’re an Arch Linux (Arm) fan, there are fewer choices, and you may have to roll your own port for your board. BredOS provides an easy-to-use alternative based on Arch Arm Linux. BredOS highlights (provided by the developers): User-Friendly Interface – A simplified and intuitive user interface for easy navigation and use. Arch-Based – Built on top of Arch Linux, ensuring access to a vast repository of packages and a rolling release model. Arm Support – Optimized for Arm-based […]

Vulkan 1.4 3D graphics and compute API released

The Khronos Group has just announced the release of Vulkan 1.4 cross-platform 3D graphics and compute API. The new release makes some of the optional extensions and features mandatory, adds streaming transfers, and supports 8K rendering on up to eight targets. Minimum hardware limits have also been increased including at least seven maxBoundDescriptorSets and eight maxColorAttachments. Vulkan 1.4 highlights: Streaming Transfers: new implementation requirements to ensure applications can stream large quantities of data to a device while simultaneously rendering at full performance. Previously optional extensions and features critical to emerging high-performance applications are now mandatory in Vulkan 1.4, ensuring availability across multiple platforms. These include push descriptors, dynamic rendering local reads, and scalar block layouts. Maintenance extensions up to and including VK_KHR_maintenance6 are now part of the core Vulkan 1.4 specification. 8K rendering with up to eight separate render targets is now guaranteed to be supported, along with several other […]

Renesas RZ/T2H Cortex-A55/R52 industrial MPU and Dev Board support EtherCAT, PROFINET, and TSN

Renesas RZ/T2H industrial MPU is the most powerful member of its RZ/T2 series of real-time microprocessors. The MPU features four Arm Cortex-A55 CPUs for application tasks and two Cortex-R52 CPUs for real-time control. It supports 9-axis motor control with 3-phase PWM timers, delta-sigma interfaces, and encoder interfaces. It also supports Industrial Ethernet protocols like EtherCAT, PROFINET, and TSN. These features make it ideal for industrial applications such as industrial robots, PLCs, motion controllers, and CNC machines. Renesas launched the RZ/T2L single-core Arm Cortex-R52 MPU just last year, and before that, in 2022, they launched the RZ/T2M dual Arm Cortex-R52 MPU. The RZ/T2L was just a cost-down version of RZ/T2M with an EtherCAT controller, compared to those old controllers the latest RZ/T2H supports 9-axis motor control and compatibility with various industrial Ethernet protocols. Renesas RZ/T2H specifications: CPU 4x Arm Cortex-A55 (64-bit) clocked at up to 1.2GHz with 32KB L1 I/D cache, 1MB L3 cache 2x […]

Qualcomm QCC730M dual-band WiFi 4 and QCC74xM WiFi 6, BLE 5.3, and 802.15.4 modules target low-power and IoT edge devices

Qualcomm has added two new IoT modules to its wireless connectivity product series: the Qualcomm QCC730M ‘micro-power’ WiFi 4 module and the QCC74xM tri-radio module, with both modules designed for smart homes, smart appliances, medical devices, and industrial applications. The Qualcomm QCC730M is a dual-band, micro-power Wi-Fi 4 module with a 60MHz Arm Cortex-M4F MCU, 640kB SRAM, 1.5MB RRAM, hardware crypto accelerator, and secure boot, debug, and storage. Its low-power design is ideal for portable, battery-powered IoT devices like IP cameras, sensors, and smart locks. Based on the Qualcomm QCC730 module, it features a 36-pin LGA package with a PCB antenna or RF connector and supports up to 4MB of optional NOR flash. The Qualcomm QCC74xM is Qualcomm’s “first programmable connectivity module,” integrating a 32-bit RISC-V module, optional stacked memory (PSRAM and NOR flash), and a tri-radio chipset for WiFi 6, Bluetooth 5.3, and IEEE 802.15.4 (Thread and Zigbee). Its […]

GenBook RK3588 modular Linux laptop features an octa-core Arm CPU module with 32GB RAM (Crowdfunding)

GenBook RK3588 is a modular Linux (and Android) laptop powered by a Rockchip RK3588 Arm system-on-module (SoM), and easily serviceable by the user who can add M.2 MVMe SSD storage, switch wireless module, and eventually update to a more powerful SoM, or even change the display. It looks very similar to the Cool Pi Arm Linux laptop, and it’s indeed made by the same company, but a representative told CNX Software that the GenBook RK3588 was an upgrade of the Cool Pi without further details. So let’s have a closer look. GenBook RK3588 laptop specifications: System-on-Module – GenM5 (same as Cool Pi CM5 except for the move from LPDDR4/4X to LPDDR5) SoC – Rockchip RK3588 octa-core processor with 4x CortexA76 cores, 4x CortexA55 cores Arm Mali-G610 MP4 GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, VP8 Video encoder – 8Kp30 H.265/H.264 video […]

MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements

Micropython v1.24 with ESP32-C6 and RP2350 support

MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: … include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good […]

Upcoming Rockchip RK3688 Armv9.3 AIoT processor to feature a 16 TOPS NPU, UFS 4.0 interface

Rockchip has unveiled the RK3688 AIoT SoC with Armv9.3 Cortex-A7xx cores delivering up to 250K DMIPS (RK3588 delivers 93K DMIPS), a 1 TFLOPS GPU, and a 16 TOPS NPU. The new processor succeeds the Rockchip RK3588 octa-core Cortex-A76/A55 first announced in 2019, and also features a 128-bit LPDDR4/4x/5 memory interface, and a UFS 4.0 storage interface. That’s about all we know about the RK3688 right now, but we can also deduct it’s probably based on a new, yet-to-be-announced Arm Cortex-A7xx core, possibly named Cortex-A730 or Cortex-A735, because no Arm cores have been announced with the Armv9.3 architectures. The Arm Cortex-A725 CPU core unveiled last May still relies on Armv9.2, and I’d expect new Arm cores to be introduced within the next few months unless Rockchip made a mistake in the presentation slide above. Two other platforms were also announced at the same time starting with a new entry-level/mid-range RK35XX octa-core […]
