Armbian 23.02 out with Linux 6.1, DietPi 8.14 adds experimental RISC-V support

Armbian 23.02

Two of the most popular projects providing images for Arm and RISC-V single board computers have released new updates with Armbian 23.02 adding Linux 6.1-based Debian and Ubuntu images, and DietPi 8.14 adding experimental RISC-V support for the StarFive VisionFive 2 SBC and new Arm boards. Armbian 23.02 Quoll Linux 6.1 is the latest LTS kernel, so Armbian is now providing Ubuntu 22.04 Jammy and Debian 11 Bullseye images based on Linux 6.1.y for boards that support it, as well as the first development images based on Debian 12 Bookworm and Ubuntu 23.04 Lunar. I could not find any new boards added in the changelog, but the release brings several improvements and bug fixes to some of the already supported SBCs including the Raspberry Pi 3, Orange Pi R1 Plus LTS, ROCK Pi S, ROCK Pi 4,  NanoPi R2S, NanoPi NEO3, and Banana Pi BPI-M2 Pro. The announcement also highlights […]

Amlogic S928X specifications – A penta-core Arm Cortex-A76/A55 SoC with Mali-G57 GPU, 3.2 TOPS NPU

Amlogic S928X block diagram

Amlogic S928X Cortex-A76/A55 will soon power some 8K TV boxes running Android TV from SDMC and others, and we now have detailed specifications as a “Quick Reference Manual” dropped in my inbox last night. While like most Amlogic processors, the S928X is designed for TV boxes, the penta-core SoC may end up in affordable yet powerful single board computers with features such as HDMI 2.1a, Gigabit Ethernet, PCIe 2.0 or USB 3.0. Amlogic S928X specifications: CPU sub-system 1x Arm Cortex-A76 core and 4x Arm Cortex-A55 cores in big.LITTLE configuration NEON and Crypto extensions Private L2 cache and unified system L3 cache Build-in RISC-V core for system control processing GPUs Arm Mali-G57 MC2 3D GPU with support for OpenGL ES 3.2, Vulkan 1.2, and OpenCL 2.0 2.5D graphics processor for scaling, alpha, rotation, and color space conversion operations VPU Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders Decoding AV1 […]

Raspberry Pi Debug Probe eases bare metal development for $12

Raspberry Pi Debug Probe

The Raspberry Pi Debug Probe is a USB serial adapter based on the Raspberry Pi RP2040 microcontroller and designed to debug the Raspberry Pi Pico, third-party RP2040 boards, and pretty much any Arm board through SWD and/or UART interfaces. The main advantage over a typical USB-to-serial adapter is the presence of a Serial Wire Debug (SWD) bridge used for bare metal code development and debugging through tools such as OpenOCD. The Raspberry Pi Debug Probe specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB SPI flash (W25Q16JVUXIQ) Debug interfaces 3.3V Serial Wire Debug (SWD) 3-pin JST connector conforming to the Raspberry Pi Debug Connector Specification and compatible with the CMSIS-DAP standard 3.3V serial (UART) 3-pin JST connector USB – Micro USB port to connect to the host Misc BOOTSEL button for flashing firmware to the debug board Unpopulated 3-pin header with […]

Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.2 release

Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]

Balthazar – An open-source hardware modular RISC-V, Arm, or FPGA laptop

Balthazar RISC-V laptop

The Balthazar Personal Computing Device (BPCD) is an open-source hardware 13.3-inch laptop with a RISC-V, Arm, or FPGA module and designed to be upgradable, expandable, and sustainable. The developers say the laptop is based on a few concepts inspired by the EOMA68 project. The EOMA68 is a CPU module based on the PCMCIA form factor, and an Allwinner A20 EOMA68 module was showcased in a prototype of the Rhombus Tech 15.6-inch Libre Laptop but I don’t think the project was ever manufactured. Balthazar laptop features: SoM with RISC-V, FPGA, or Arm Cortex-A7x processor plus memory and flash Storage – SATA SSD, eSATA connector, microSD card socket Display – 13.3-inch non-glare display Video Output – HDMI Audio – Speakers, detachable microphone array Camera – Detachable webcam Connectivity – Ethernet, WiFi USB – 2x USB 3.0 ports, Micro USB OTG port, Micro USB port User input Waterproof keyboard with an illuminated track-point […]

Meet Puya PY32 – The 8-cent Arm Cortex-M0+ microcontroller

PY32 MCU development board

Puya Semiconductor (Shanghai) PY32 Arm Cortex-M0+ microcontroller family may be the world’s cheapest 32-bit Arm MCUs with one of the parts – PY32F002AL15S6TU –  selling for under 8 cents per unit in 5K+ orders with 3KB SRAM, 20KB flash in an 8-pin SOP-8 package. Back in 2016, when I searched for the world’s cheapest MCU, I found Holtek HT48R002 8-bit microcontroller, and a few years later (2019), Padauk PMS150C “3 Cents” MCU came to my attention. However, both are 8-bit microcontrollers that come with OTG (One-Time Programming) ROM, meaning they can’t be easily used for development or updated. The Puya PY32 microcontrollers are in the same price range but offer a 32-bit Arm Cortex-M0+ core clocked at 24 to 48MHz, 16KB to 64KB flash storage, and 2KB to 8KB SRAM. There are three PY32 sub-families, but let’s check out the PY32F002 family in detail since those are the cheapest parts. […]
