    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 3A
• ROCK 3B
• Radxa CM3 IO Board
• Radxa E23
• Radxa E25

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 4.19.193-25-rockchip.

root@rock-3a:/home/rock# uname -r
4.19.193-25-rockchip-g56fae2db273e

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 Prebuilt RKNN2 SSD DEMO

Install curl tool.

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 b03a1b3c236b83def933090c846d24f5. And extract it.

root@rock-3a:/home/rock# curl https://dl.radxa.com/rock3/npu/rknn_ssd_demo_linux_20220728.tar.gz > rknn_ssd_demo_linux_20220728.tar.gz
root@rock-3a:/home/rock# md5sum rknn_ssd_demo_linux_20220728.tar.gz 
f8ed06c1409155ab0bbe08dc27430463  rknn_ssd_demo_linux_20220728.tar.gz
root@rock-3a:/home/rock# tar zxvf rknn_ssd_demo_linux_20220728.tar.gz

Check RKNN runtime version. Here it is 1.3.0.

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: 1.3.0 (9b36d4d74@2022-05-04T20:17:01)

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# ./rknn_ssd_demo model/RK356X/ssd_inception_v2.rknn model/bus.jpg
resize 640 640 to 300 300
Loading model ...
rknn_init ...
model input num: 1, output num: 2
input tensors:
  index=0, name=Preprocessor/sub:0, n_dims=4, dims=[1, 300, 300, 3], n_elems=270000, size=270000, fmt=NHWC, type=UINT8, qnt_type=AFFINE, zp=0, scale=0.007812
output tensors:
  index=0, name=concat:0, n_dims=4, dims=[1, 1917, 1, 4], n_elems=7668, size=30672, fmt=NCHW, type=FP32, qnt_type=AFFINE, zp=53, scale=0.089455
  index=1, name=concat_1:0, n_dims=4, dims=[1, 1917, 91, 1], n_elems=174447, size=697788, fmt=NCHW, type=FP32, qnt_type=AFFINE, zp=53, scale=0.143593
rknn_run

bus @ (87 132 567 433) 0.989999
person @ (211 225 290 513) 0.829137

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

Step4: Run Your Own Built RKNPU Demo

You can get more rknpu demo from RK356X NPU SDK.
