Sipeed Lichee Book 4A 14-inch modular Linux laptop launched with TH1520 quad-core RISC-V processor

Sipeed Lichee Book 4A

We’ve just written about Deep Computing’s DC-ROMA RISC-V Laptop II, but Sipeed has just launched the Lichee Book 4A modular RISC-V laptop based on the quad-core Alibaba T-head TH1520 processor and running Debian Linux. I was expecting the Lichee Book to launch with the SpacemIT K1 octa-core RISC-V processor, but Sipeed started with the time-tested TH1520 quad-core RISC-V processor coupled with up to 16GB RAM and 128GB eMMC flash and equipped with a 14-inch IPS display. In the future, we’ll get the Lichee Book 3A with the SpacemIT K1, and the Lichee Book 5A with an unnamed Cortex-A75-class RISC-V SoC with a 20 TOPS AI accelerator. Sipeed Lichee Book specifications: 260-pin SO-DIMM system-on-module (SoM) Sipeed LM3A – Upcoming module based on SpacemIT K1 octa-core RISC-V CPU (Cortex-A55 class) with 2 TOPS NPU Sipeed LM4A SoC – Alibaba T-Head TH1520 CPU Quad-core RISC-V Xuantie C910 (RV64GCV – RVV 0.7) processor @ […]

Linux 6.9 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.9 release

Linus Torvalds has just announced the release of Linux 6.9 on LKML: So Thorsten is still reporting a few regression fixes that haven’t made it to me yet, but none of them look big or worrisome enough to delay the release for another week. We’ll have to backport them when they get resolved and hit upstream. So 6.9 is now out, and last week has looked quite stable (and the whole release has felt pretty normal). Below is the shortlog for the last week, with the changes mostly being dominated by some driver updates (gpu and networking being the big ones, but “big” is still pretty small, and there’s various other driver noise in there too). Outside of drivers, it’s some filesystem fixes (bcachefs still stands out, but ksmbd shows up too), some late selftest fixes, and some core networking fixes. And I now have a more powerful arm64 machine […]

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

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 […]

Sipeed MaixBox M4N AI Box with 43.2 TOPS AXera AX650N SoC can decode/encode up to 32 videos

Sipeed MaixBox M4N AI box

Sipeed MaixBox M4N is an AI box for video analytics and computer vision equipped with an AXera-Pi Pro (AX650N) octa-core Cortex-A55 SoC with a 43.2 TOPS (INT4) or 10.8 TOPS (INT8) AI accelerator and an H.265/H2.64 video encoder/decoder supporting up to 32 1080p30 videos. The AI box is based on the Sipeed Maix-IV motherboard, an upgrade to the Maix-III devkit with an AX620A quad-core Cortex-A7 SoC with a 14.4 TOPS AI accelerator (INT4). It comes with 8GB RAM shared for Linux and the AI accelerator, 32GB eMMC flash and an M.2 SATA socket for storage, two HDMI outputs, two gigabit Ethernet ports, optional WiFi or 4G LTE mini PCIe module, a few USB ports, and RS232 and RS485 interfaces.

Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.8 release

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

LicheeRV Nano – A low-cost SG2002 RISC-V and Arm camera and display board with optional WiFi 6 and/or Ethernet

SG2002 camera development board

When I wrote about the SOPHGO SG2002 (and SG2000) RISC-V, Arm, and 8051 AIoT processor yesterday, I noted several boards were in development, but I had not noticed the Sipeed LicheeRV Nano (Beta) was already available for sale, so let’s have a closer look. It’s an inexpensive, tiny camera and display board running Linux with optional support for WiFi 6 and 10/100M Ethernet connectivity which somewhat reminds me of the Breadbee SBC based on MStar MSC313E Camera SoC. Sipeed also provides accessories such as a camera module and a touchscreen display to quickly get started. LicheeRV Nano specifications: SoC – SOPHGO SG2002 Main core – 1GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700MHz 64-bit RISC-V C906 core Low-power core – 25 to 300MHz 8051 MCU core NPU – 1 TOPS INT8, supports BF16 Integrated 256MB DDR3 (SiP) Storage – MicroSD card slot and SD NAND […]

SOPHGO SG2000/SG2002 AI SoC features RISC-V, Arm, and 8051 cores, supports Android, Linux, and FreeRTOS

SOPHGO SG2000 SG2002 block diagram

SOPHGO SG2000 and SG2002 are new SoCs featuring a bunch of RISC-V and Arm cores capable of running Linux, Android, and FreeRTOS simultaneously, and to maximize the fun an 8051 MCU core is also in the mix along with a 0.5 TOPS (SG2000) or 1 TOPS (SG2002) AI accelerator. More specifically we have one 1GHz C906 64-bit core capable of running Linux, one 1GHz Arm Cortex-A53 for Linux or Android, another 700 MHz C906 RISC-V core for FreeRTOS, and a 300 MHz 8051-core for real-time I/Os, as well as 256MB or 512MB SiP DRAM. The chip is designed for AIoT applications such as Smart IP cameras, facial recognition, and smart home devices.
