Khadas VIM4 Review – Part 2: Android 11 preview and benchmarks

In the first part of Khadas VIM4 review, I showed off the Amlogic A311D2 SBC and some accessories such as the DIY case and M2X expansion board to add M.2 SSD and modem and tried out OOWOW cloud services to install Ubuntu 20.04 server. I’ve now just gotten Fiber Internet at home, so it’s much more practical to test the system, and in the second part of the review, I’ve installed Android 11 on the VIM4 board, checked out settings and system info, and ran some benchmarks.  It will be more like a preview since Android 11 is not a consumer-friendly system at this time, and is more designed for people wanting to build their own applications. Installing Android 11 on Khadas VIM4 with OOWOW system Last time around, I used OOWOW system install in the SPI flash on the board to download and install Ubuntu 20.04 server to the […]

Orbbec Persee+ 3D AI camera runs Ubuntu or Android on Amlogic A311D processor

Orbbec Persee+ is a 3D depth camera running Linux with AI capabilities thanks to Amlogic A311D hexa-core processor equipped with a 5 TOPS NPU (Neural-network Processing Unit). The Persee+ is designed to help researchers, engineers, and hobbyists implement advanced uses for 3D imaging. Orbbec has been around for several years with the first product we covered here being the Orbbec Persee 3D depth camera running Ubuntu or Android on Rockchip RK3288 processor and unveiled in 2015. Last year, the company introduced the Zora P1 Amlogic A311D development board for Orbbec 3D cameras, so in a way, the Orbbec Persee+ is born from the work done on the Persee camera and Zora P1 over the years. Orbbec Persee+ 3D AI camera specifications: SoC – Amlogic A311D hexa-core processor with 4x Cortex-A73 cores, 2x Cortex-A53 cores, Arm Mali-G52MP4 GPU, 5 TOPS NPU System Memory – 4GB RAM Storage – 8GB (specs) / […]

Eben Upton expands on Raspberry Pi shortage

As you may have noticed, Raspberry Pi boards may get hard to get and/or be sold at excessive prices by some resellers. Eben Upton explains the reasons behind the Raspberry Pi Shortage and provides some recommendations to work around the shortage and high prices. Raspberry Pi Trading is still manufacturing around 500,000 Raspberry Pi boards or modules per month despite the global semiconductors shortage, and the issue they face is more of a demand shock than a supply shock with demand for Raspberry Pi products having increased sharply from the start of 2021 and remains unabated as the supply chain can not handle that extra demand at this time. That means distributors have backlogs in almost all products, and it takes time for customers to get their orders. Bots are also involved in making automatic purchases as soon as stock becomes available often in order to resell those boards at […]

Lakka 4.0 game emulator released with LibreELEC 10.0.2 and RetroArch 1.10.1

Lakka 4.0 is the latest release of the game emulator based on LibreELEC 10.0.2 and RetroArch 1.10.1 frontend GUI for LibRetro game emulators cores. While Lakka was initially designed for Raspberry Pi boards in a way similar to RetroPie, it also works just fine on many other Arm platforms and PCs. Main changes to Lakka 4.0 compared to version 3.7: Build system based on LibreELEC 10.0.2 RetroArch updated to 1.10.1 Cores updated to their most recent versions superbroswar: added new libretro core sameduck: added new libretro core Mesa updated to 22.0.0 Mainline kernel updated to 5.10.103 (PC, Amlogic, Allwinner, NXP) Raspberry kernel updated to 5.10.95 Most arm devices switched to aarch64 Rockchip RK3288, RK3328 and RK3399 switched to mainline kernel 5.10.76 Added support for additional Allwinner and Amlogic devices (not tested on our side, as we do not own many of these devices) Nintendo Switch: complete rewrite of the port […]

Dongshan Nezha STU devkit features Allwinner D1 RISC-V SoM/SBC

Dongshan Nezha STU is a development kit comprised of an Allwinner D1 RISC-V system-on-module (SoM) and a carrier board with three 40-pin headers to access I/Os from the RISC-V processor. While not quite as compact as the Sipeed LicheeRV module, the “Dongshan Nezha STU Core” module also doubles as a standalone single board computer (SBC) with USB-C, Ethernet and HDMI ports, plus a MicroSD card socket for the firmware, which reminds me of the Khadas Edge design. Dongshan Nezha STU specifications: Nezha STU Core SoM SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 512MB DDR3 memory (option up to 2GB – TBC) Storage – MicroSD card slot, 2Gbit serial NAND flash (MX35LF1GE4AB); Note the SPI NAND flash (U12) is not populated in the photo below. Video – HDMI port up to 1080p60 Networking – Low-profile Gigabit […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]
