Rockchip RK1808 Datasheet, TRM, Schematics and Linux SDK Released

Rockchip RK1808 Block Diagram

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:

Finally configure the build and start the build process:

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 IMAGE/RK1808-EVB-V10_20190430.1810_RELEASE_TEST/ directory:

Now the only available development board is […]

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 generate the correct code. In order to achieve this, extensive […]

Embedded Base Boot Requirements (EBBR) Project Aims to Standardize Booting on Embedded Systems


Desktop and server systems relies on standardized interfaces between the bootloader and the OS like UEFI and ACPI, but for embedded systems the way the bootloader, often U-boot, handles the boot flow may vary greatly between targets. Arm and its partners already worked on this in the server space with the Server Base Architecture Specification (SBSA) , and more specifically the Server Base Boot Requirements (SBBR) within the specification that requires the use of both UEFI and ACPI on servers.  Arm has now done something similar with the Embedded Base Boot Requirements (EBBR) project that targets specifically embedded systems, is based on a subset of UEFI, and works with either ACPI or device tree. EBBR specification once implemented in bootloaders like  U-boot or Tianocore/EDK2 should allow a single version of an OS image to boot on multiple platforms without the per-platform customization required today.. In practical terms it means the U-Boot would have a standardize interface with the OS based […]

FOSDEM 2018 Open Source Developers Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) occurs every year on the first week-end of February, where developers meet for two days discussing about open source software projects. FOSDEM 2018 will take place on February 3-4 this year with  652 speakers, 684 events, and 57 tracks, an increase over  last year 608 speakers, 653 events, and 54 tracks. There will be 8 main tracks namely: Community, History, Miscellaneous, Performance, Python, Security and Encryption, Space, and Global Diversity CFP Day. There will also be 33 developer rooms, and since the full schedule is now available, I’ll make a virtual schedule mostly based on sessions from the Embedded, mobile, and automotive, Hardware Enablement, and Internet of Things devrooms. Saturday 3, 2018 09:50 – 10:15 – Turning On the Lights with Home Assistant and MQTT by Leon Anavi In this presentation you will learn the exact steps for using MQTT JSON Light component of the open source home automation platform Home […]

Compulab CL-SOM-iMX8 SoM Features NXP i.MX 8M Processor for $68 and Up

I just covered one of the i.MX 8M systems-on-module last Friday with Variscite DART-MX8M SoM, but Variscite is not the only company about to launch such modules, and today I’ll have a look at Compulab CL-SOM-iMX8 system-on-module based on the same NXP i.MX 8M dual or quad core Cortex A53 processor. Compulab’s SoM comes with up to 4GB RAM, 64GB eMMC flash, an optional WiFi & Bluetooth module, as well as optional support for Ethernet, LVDS, analog audio, and more. Contrary to most competitors, the company has also made an habit of releasing detailed pricing the basic configuration and per option. But first, let’s go through the specifications: SoC (one of the other) NXP i.MX8M Quad quad core Arm Cortex-A53 processor @ 1.5GHz with Arm Corex-M4 real-time core, Vivante GC7000Lite GPU supporting OpenGL ES 3.1, Open CL 1.2 and Vulkan NXP i.MX8M Dual dual core Arm Cortex-A53 processor @ 1.5GHz with Arm Corex-M4 real-time core, Vivante GC7000Lite GPU supporting OpenGL […]

U-Boot Now Supports UEFI on 32-bit and 64-bit ARM Platforms

Intel/AMD x86 based computers now boot via a standard UEFI binary, which can load grub2, allows you to update the command line as needed, or select different version of the Linux kernel. On ARM everything is a little more complicated and messy, as bootloaders such as U-boot need to support different configurations formats. Alexander Graf has been working on implementing UEFI support in U-boot, and it’s now supported by U-boot mainline and enabled by default for 32-bit and 64-bit ARM platforms, but not x86-64 (yet). That means you should now be able to boot any ARM boards supported by mainline U-boot through UEFI. Alexander gave a presentation about his work at an openSUSE event in June, and demonstrated u-boot with UEFI, and GRUB2 support with an openSUSE image running on a Raspberry Pi board. Thanks to David for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering […]
