Raspberry Pi CM4 compatible RISC-V SoM features StarFive JH7110 SoC

We’ve seen many Arm-based system-on-modules following the Raspberry Pi CM4 form factor, but we’ve now got a RISC-V one courtesy of the Milk-V Mars CM CPU module powered by a StarFive JH7110 quad-core RISC-V SoC. The RISC-V module comes with up to 8GB RAM, a 16MB SPI flash, an optional eMMC flash, onboard GbE PHY, and a wireless module with WiFi 5 and Bluetooth 5.2 plus the two 100-pin board-to-board connectors offering (partial) compatibility with carrier boards made for the Raspberry Pi Compute Module 4. Specifications: SoC – StarFive JH7110 CPU – Quad-core RISC-V processor (RV64GC) at up to 1.5GHz GPU – Imagination BXE-4-32 GPU with support for OpenCL 1.2, OpenGL ES 3.2, Vulkan 1.2 VPU H.264 & H.265 4Kp60 decoding H.265 1080p30 encoding JPEG encoder / decoder System Memory – 2GB, 4GB, or 8GB LPDDR4 Storage SDIO 2.0 (options to eMMC) 16MB NOR flash Networking Gigabit Ethernet PHY (YT8513C) […]

SiFive unveils P870 high-performance core, discusses future of RISC-V

SiFive Hot Chips 2023 x86 vs Arm vs RISC-V

SiFive has just given a presentation at Hot Chips 2023 introducing the new high-performance P870 RISC-V core and its automotive equivalent the P870-A core, plus discussing RISC-V in general, its previous generation RISC-V cores, and what to expect going forward. SiFive has not officially announced the P870 and P870-A cores just yet, so most of the information we have from the English-speaking Internet is from ServeTheHome who managed to get some presentation slides, but this is also corroborated by various Chinese sources on Baidu and Guokr. SiFive P870 and P870-A The P870 and P870-A RISC-V cores are new cores from the SiFive Performance family compatible with the RISC-V RVA23 profile and succeeding the SiFive P670 core. The SpecINT2k6 benchmark reports 17 points per GHz on the P870 compared to 13.2 points per GHz for the P670 (comparable to the Arm Cortex-A78) or about a 29% higher performance at the same […]

Sipeed unveils RISC-V tablet, portable Linux console, and cluster

Sipeed RISC-V tablet, cluster, Linux console

Sipeed has unveiled three new hardware platforms based on the LM4A RISC-V system-on-module found in their LicheePi 4A SBC, namely the Lichee Cluster 4A cluster for native RISC-V compilation, the Lichee Pad 4A 10.1-inch tablet running Android 13 or Debian, and the Lichee Console 4A a portable Linux console with a small 7-inch display and a built-in keyboard. As a quick reminder, the Sipeed LM4A SoM is based on the Alibaba T-Head TH1520 quad-core RISC-V processor @ 1.8 to 2.5 GHz that has just gotten some support in Linux 6.5, comes with up to 16GB RAM and up to 64 GB eMMC flash, integrates two Gigabit Ethernet PHY, and exposes all I/Os through a 260-pin SO-DIMM connector. We’ve previously noticed the TH1520 module delivers performance similar to the Raspberry Pi Compute Module 4 and even more when using a customized toolchain. Lichee Cluster 4A All new Sipeed hardware platforms feature […]

Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

Star64 RISC-V SBC can now boot Apache NuttX real-time operating system

Most of the software development efforts on the more powerful RISC-V boards like Pine64 Star64 or StarFive VisionFive 2 have been focusing on Linux, but Lup Yuen Lee tried something different and managed to boot Apache NuttX real-time operating system on the StarFive JH7110-powered Star64 SBC. NuttX may not often make the news, but they are plenty of supported platforms, and we previously played with it on the Sony SPresense board, and reported about NuttX RTOS on ESP32, so it’s good seeing the open-source real-time operating system add support for the RISC-V architecture. [Update: RISC-V support was added many years ago, sometimes around 2016] The main trick to boot NuttX on the Star64 is to make U-boot think the NuttX kernel is the Linux kernel. That means a Linux image such as sdcard.img for the VisionFive 2 board will be used to get OpenSBIU and U-boot bootloaders, and the NuttX […]
