Rockchip RK1808 Datasheet, TRM, Schematics and Linux SDK Released

Rockchip RK1808 is the first chip from the company fully dedicated to artificial intelligence applications. The Neural Processing Unit (NPU) features an accelerator delivering up to 3.0 TOPS and is coupled with two low power Arm Cortex-A35 cores allowing it to run Linux. We’ve had the specifications for RK1808 for a while, but the company has recently posted hardware and software resources on their open source website. On the hardware side we’ve got: RK1808 Technical Reference Manual (TRM) RK1808 datasheet PDF Schematics for the company’s official RK1808-EVB On the software side we can get the Linux SDK from Github as explained in the Wiki:

git clone https://github.com/rockchip-linux/repo
mkdir linux
cd linux
../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml
../repo/repo sync

git clone https://github.com/rockchip-linux/repo

mkdir linux

cd linux

../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml

../repo/repo sync

Finally configure the build and start the build process:

sudo apt install liblz4-tool build-essential
source envsetup.sh rockchip_rk1808
./build.sh

sudo apt install liblz4-tool build-essential

source envsetup.sh rockchip_rk1808

./build.sh

After a while, or more accurately close to two hours on a Laptop with Ryzen 7 2700U processor, 8GB RAM, and hard drive, we’ll get U-boot, Linux, buildroot based rootfs, and firmware files and in […]

Nitrogen8M_Mini Single Board Computer Launched for $135 and Up

Last month we write about Nitrogen8M_Mini, the First NXP i.MX8 8M Mini SBC, but at the time, it was not available for purchase just yet. Boundary Devices has now announced the official release of the board and is taking orders / pre-orders for $135 and up.

4Kopen UHD Video Development Platform Features STMicro STiH418 Media Processor

Back in 2016, I read news about STMicro exiting the set-top box chipset market, so I just assumed all their STiHxx processors would be phased out, and I was surprised to come across 4Kopen, described as an open 4K UHD video development platform powered by STMicro STiH418 media processor, especially it was just showcased at 2019 Integrated Systems Europe (ISE 2019) at the beginning of the month. The development board comes with 2 GB RAM, HDMI 2.0 output, HDMI 1.4 input, Gigabit Ethernet, USB 3.0, a mini PCIe slot fitted with an 802.11b/g/n WiFi module, an eSATA connector and more. 4Kopen (B2264) hardware specifications: SoC – STMicro STiH418 quad-core Arm Cortex-A9 processor @ 1.2 GHz, quad-core Mali-400 GPU, and 4x ST231 DSP (Each Core Quad issue) @ 650 MHz System Memory – 2 GB DDR3 @ 2133 MHz Storage – micro SD socket, eSATA port Video & Audio I/O Output […]

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to […]

Buildroot For NanoPi NEO4 RK3399 SBC

NanoPi NEO4 is the smallest and cheapest RK3399 board so far, featuring the hexa-core processor into a $45 60×45 mm single board computer. FriendlyELEC usually provides decent documentation and software support for their boards, but Flatmax was not satisfied with the build system provided by Rockchip / FriendlyELEC. So he took the matter into his own hands, worked on and released a buildroot external tree for building NanoPi NEO4 SD card images. Flatmax mentioned this is the first completely contained build system for the NanoPi NEO4. The build process is explained on Github, and basically goes like this: Clone buildroot

git clone git://git.busybox.net/buildroot buildroot.neo4

1	git clone git://git.busybox.net/buildroot buildroot.neo4

Install dependencies

sudo apt-get install -y build-essential gcc g++ autoconf automake libtool bison flex gettext
sudo apt-get install -y patch texinfo wget git gawk curl lzma bc quilt

1 2	sudo apt-get install -y build-essential gcc g++ autoconf automake libtool bison flex gettext sudo apt-get install -y patch texinfo wget git gawk curl lzma bc quilt

Clone NEO4 buildroot external tree

git clone git@github.com:flatmax/NanoPi.Neo4.buildroot.external.git NanoPi.Neo4

1	git clone git@github.com:flatmax/NanoPi.Neo4.buildroot.external.git NanoPi.Neo4

Build the system

. NanoPi.Neo4/setup.sh yourPath/buildroot.neo4
mkdir yourPath/buildroot.dl
make

. NanoPi.Neo4/setup.sh yourPath/buildroot.neo4

mkdir yourPath/buildroot.dl

make

Flash it to the micro SD card

sudo ./output/images/sd-fuse-rk3399/fusing.sh /dev/sdX buildroot

1	sudo ./output/images/sd-fuse-rk3399/fusing.sh /dev/sdX buildroot

Just replace /dev/sdX with your actual SD card device. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software […]

Amlogic A311D Media Processor Features Cortex A73/A53 Cores, an Arm Mali-G52 MP4 GPU

As far as processors are concerned, it’s been pretty quiet in the TV box space in this year with for example, devices based on Amlogic S922 yet to launch, and new TV boxes are normally launched with processors such as Amlogic S905X/Z/W or S912, as well as Rockchip RK3328 or RK3229. But this morning, I’ve been informed that Amlogic is working on a more powerful media processor based on info from buildroot release notes Amlogic A311D is an hexa-core processor featuring four Arm Cortex A73 cores, two Cortex A53 cores, and an Arm Mali-G52-MP4 GPU. Amlogic A311D specifications known so far: CPU – 4x Arm Cortex A73 @ TBD GHz, 2x Arm Cortex A53 GPU – Arm Mali-G52 MP4 Memory I/F – DDR3/4; LPDDR3/4 Storage I/F – eMMC, SD/SDHC/SDXC Video Output – HDMI Tx up to 4K2K @ 60 Hz with CEC & HDR support, CVBS Video Processing Unit (VPU) […]
