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.
- 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
../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
Finally configure the build and start the build process:
sudo apt install liblz4-tool build-essential
source envsetup.sh rockchip_rk1808
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:
build_cmd_info IMAGES manifest_20190430.1810.xml PATCHES
boot.img oem.img rootfs.img update.img
MiniLoaderAll.bin parameter.txt trust.img userdata.img
misc.img recovery.img uboot.img
Now the only available development board is the RK1808-EVB from Rockchip which won’t be for sale to the general maker community, so we may have to patiently wait until one of the SBC’s companies decides to design one.
Thanks to Jon for the tip.
