    ROCK 3 >  Development >  NPU Run Test

Description

SoC RK3568 is equipped with 0.8TOPS NPU. This tutorial shows how to make the NPU run on ROCK 3 A, and provides an example and test results.

Hardware supported

• ROCK 3 A
• Radxa CM3 IO Board
• Radxa E23

Now follow me to make the NPU run.

Setup steps

Step 1: Get system image

You can get system image from ROCK 3 A System images.

Here we are concerned about the kernel version. Make sure that kernel is at least 4.19.193-17-rockchip.

root@rock-3a:/home/rock# uname -a
Linux rock-3a 4.19.193-17-rockchip-ga4e78ea509f7 #rockchip SMP Fri Nov 19 16:59:52 CST 2021 aarch64 GNU/Linux

If not, try to upgrade the kernel via the following commands.

Uncomment "deb http://apt.radxa.com/buster-testing/ buster main" in file /etc/apt/sources.list.d/apt-radxa-com.list. Here I use debian buster image. So its content is

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

If you use ubuntu focal image, It should be like this

deb http://apt.radxa.com/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal main

After saving that file, now we install the latest kernel packages.

root@rock-3a:/home/rock# apt update
root@rock-3a:/home/rock# apt install -y linux-4.19-rock-3-latest

Then reboot the device. Use command 'uname -a' to check the kernel verison again.

Step 2: Get RKNN2 SSD DEMO

Install 7z and curl tools.

root@rock-3a:/home/rock# apt update
root@rock-3a:/home/rock# apt install -y curl

Get rknn_ssd_demo_Linux.zip package, check the md5 of file. It should be 51d85886553225923790dd1ab895f54f. And extract it.

root@rock-3a:/home/rock# curl https://dl.radxa.com/rock3/npu/rknn_ssd_demo_Linux.zip > rknn_ssd_demo_Linux.zip
root@rock-3a:/home/rock# md5sum rknn_ssd_demo_Linux.zip 
51d85886553225923790dd1ab895f54f  rknn_ssd_demo_Linux.zip
root@rock-3a:/home/rock# unzip rknn_ssd_demo_Linux.zip

Check RKNN runtime version. Here it is 1.1.0.

root@rock-3a:/home/rock# cd rknn_ssd_demo_Linux
root@rock-3a:/home/rock/rknn_ssd_demo_Linux# strings lib/librknnrt.so | grep version
librknnrt version: 1.1.0 (8a9d6f66@2021-08-19T15:09:11)

Step3: Run RKNN2 SSD DEMO

These are test commands and result.

root@rock-3a:/home/rock/rknn_ssd_demo_Linux# export LD_LIBRARY_PATH=./lib/
root@rock-3a:/home/rock/rknn_ssd_demo_Linux# chmod +x rknn_ssd_demo
root@rock-3a:/home/rock/rknn_ssd_demo_Linux# ./rknn_ssd_demo model/ssd_inception_v2.rknn model/road.bmp

You would also get the output image, out.jpg, under /home/rock/rknn_ssd_demo_Linux directory.
