Khadas is Working on more RK3399 / RK3399Pro Boards, Projector Development Kit, AR Kit

Khadas Edge-V vs Khadas Edge

Shenzhen Wesion had already unveiled their Khadas Edge board that works both as a system-on-module and a standalone SBC thanks to an MXM3 connector on one side, and traditional HDMI and USB ports on the other. The Rockchip RK3399 board will be launched on Indiegogo a little later. But the company is working on a few more boards and development kits all based on Rockchip RK3399 or the upcoming RK3399Pro processor with neural processing unit (NPU) for AI workloads acceleration. First we have Khadas Edge-V, very similar to Khadas Edge but with a 40-pin IO header replacing the MXM3 connector, and following Khadas VIM form factor and ports, so for example we get an Ethernet port as well as an extra USB 3.0 port instead of USB 2.0 on Edge. As mentioned in Khadas Edge announcement, the company is also working on Khadas Captain carrier board with MXM3 socket. So we have three options for development, and while AFAIK the company …

Khadas Edge is Both a Standalone Board and a System-on-Module powered by Rockchip RK3399

Khadas Edge

One of the two most common type of Arm boards are single board computers with everything from processor to memory/storage to ports is placed on a single PCB, and system-on-modules with processor, memory and storage, and sometimes some extra chips with for network connectivity, audio and power management that are supposed to be inserted into a baseboard exposing connectors and headers. The upcoming Khadas Edge board is a little different since it combines both categories into one board with USB receptacles and HDMI output as well as 314-pin MXM3 edge connector to connect to Khadas Captain baseboard, or any other custom compatible baseboard. Khadas Edge will come in three variants (Basic/Pro/Max) with the following specifications: SoC – Rockchip RK3399 hexa core processor with 2x Arm Cortex-A72 up to 1.8GHz, 4x Cortex-A53 up to 1.5GHz, Arm Mali T864 GPU with support for OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, VPU with4K VP9 and 4K 10bits H265/H264 video decoders up to 60fps, and 1080P H.264 …

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is worth pointing out that it’s not like we’re “done” with …

How to Use Khadas VIM2 Board with VTV Expansion DTV Board as a Live TV Streaming Server

Khadas VIM2 is the first and only Amlogic S912 based hobbyist development board on the market, which makes it interesting by itself, but the company also added some interesting features such as an SPI flash for network boot, Wake-on-LAN support, and more. Last month the company sent me a sample of the Khadas VIM2 Basic (2GB RAM/16GB flash) together with VTV Extension DTV Board featuring a DVB-T2/C and DVB-S2 tuner. I’ve already checkout the hardware and shown how to assemble the kit, so for the second part of the review it seemed like a good idea to use the board as a Live TV streaming server broadcasting satellite, cable or terrestrial TV to devices connected to the local network. At first I wanted to use Linux operating system, because I could have run other Linux server services, but SuperDVB, the company that makes and supports the tuner board, only have Android software for their board. So I changed plan, and …

Khadas VIM2 Board Review – Part 1: Unboxing and Dual Tuner Board

Khadas VIM2 board is the successor of Khadas VIM board, replacing Amlogic S905X by a slightly more powerful Amlogic S912, but that’s the connectivity features that really makes it stand apart from the first version with Gigabit Ethernet, 802.11ac WiFi and Bluetooth 4.2. It also exposes a few extra I/Os via pogopins. and among the three variants, two comes with 3GB RAM, and up to 64 GB storage. The company (Shenzhen Wesion) sent me one of the boards, together with various accessories, and I’ll start the review of the board by checking out the hardware and accessories, before testing the board further in another post. I received two packages: one book-like with Khadas marked on top, and another one with various other items. The first package includes the board, a USB to USB type C cable, and a card showing the main specifications, and supported operating systems: Ubuntu 16.04, Android 7.1. Buildroot build system is also another option to generate …

Linux 4.12 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just released Linux 4.12: Things were quite calm this week, so I really didn’t have any real reason to delay the 4.12 release. As mentioned over the various rc announcements, 4.12 is one of the bigger releases historically, and I think only 4.9 ends up having had more commits. And 4.9 was big at least partly because Greg announced it was an LTS kernel. But 4.12 is just plain big. There’s also nothing particularly odd going on in the tree – it’s all just normal development, just more of it that usual. The shortlog below is obviously just the minor changes since rc7 – the whole 4.12 shortlog is much too large to post. In the diff department, 4.12 is also very big, although the reason there isn’t just that there’s a lot of development, we have the added bulk of a lot of new  header files for the AMD Vega support. That’s almost exactly half the …

The First Amlogic S912 Development Board is Coming Soon with Khadas VIM2

We have a decent choice of Amlogic S905 development boards like ODROID-C2 or NanoPi K2, but I was recently asked whether I knew of any Amlogic S912 development boards. I’m sure Amlogic has one for internal development, but those are hard to get, and probably expensive, and while you could probably get an S912 TV box board those lack I/Os, and software support may truly be a challenge. So I’m pleased to announce that Shenzhen Wesion will soon provide an update to their Khadas VIM Pro board with Khadas VIM2 powered by Amlogic S912 octa-core processor. The company will actually offer three variants of Khadas VIM2 boards (Basic/Pro/Max) specifications with highlights in bold showing differences with Khadas VIM Pro board: SoC –  Amlogic S912 octa core ARM Cortex-A53 @ up to 1.5 GHz with ARM Mali-820MP GPU System Memory Basic – 2 GB DDR4 Pro/Max – 3 GB DDR4 Storage micro SD card and 2MB SPI flash eMMC Flash – …
