03-Functional_Testing

This document aims to help users quickly get started or test the functions of the motherboard's peripheral interfaces.

LED

There are 2 LED indicators on the motherboard:

Green LED: Power indicator. It remains constantly lit by default after power-on.
Blue LED: System heartbeat indicator. If this light flashes continuously, it indicates that the kernel is running normally.

KEY

The motherboard is equipped with four buttons with the following functions:

LOADER Button

During system startup: Used as a programming button.
When the system is running normally: Can be configured as any button as required.

RESET Button

System reset button. Pressing this button resets the system.

POWER Button

Power button, used to control the power switch of the motherboard.

MASKROM Button

The Maskrom mode is the initial state of the system when the firmware is not programmed or the firmware data is cleared. This button is usually used for system repair when the bootloader is damaged, such as flashing new firmware, unlocking the device, or rescuing a bricked device.

Ethernet

The motherboard is equipped with two Gigabit Ethernet interfaces. After connecting the network cable, the motherboard will automatically obtain an IP address and connect to the network.

USB

The motherboard has three USB 3.0 TYPE - A interfaces, supporting HOST mode. They can be connected to common USB peripherals such as mice, keyboards, cameras, and docking stations.

USB Type C

The motherboard is equipped with one USB 3.0 TYPE - C interface with the following features:

Supports automatic mode recognition and switching.
Supports HOST mode, allowing connection to USB peripherals such as mice, keyboards, cameras, and docking stations.
Supports DEVICE mode, enabling functions such as adb.
Supports DP v1.4 display output.

Chromium Video Test

Connect the board to a display device, open a virtual terminal or a debug serial terminal, and execute the following command to start the Chromium video test.

$ source /rockchip-test/chromium/test_chromium_with_video.sh

There is a compatibility issue with hardware decoding configuration between Rockchip Chromium and GStreamer in Ubuntu!

Chromium is configured for use by default. If Chromium does not call hardware decoding, use the following command to fix it.

$ source /rockchip-test/chromium/chromium_mpp_fix.sh

After configuration, Chromium can call hardware decoding by default.

GStreamer Video Test

sudo GST_DEBUG=2 gst-launch-1.0 playbin uri=file:///usr/local/test.mp4 video-sink="autovideosink" audio-sink=fakesink

If there are signs of MPP calls, it means the hardware decoding is successfully called.

There is a compatibility issue with hardware decoding configuration between Rockchip Chromium and GStreamer in Ubuntu!

Chromium is configured for use by default. If you need GStreamer to call hardware decoding, use the following command to fix it.

$ source /rockchip-test/gstreamer/gstreamer_mpp_fix.sh

This command requires an internet connection to ensure 'apt update' succeeds.
After configuration, GStreamer can call hardware decoding by default.

NPU

6 TOPS*@INT8
Support int4/int8/int16/FP16/BF16/TF32
Support deep learning frameworks: TensorFlow, Caffe, Tflite, Pytorch, Onnx NN, Android NN, etc

Debian / Ubuntu

Rockchip provides NPU test scripts.

# ls /rockchip-test/npu2
model  npu_freq_scaling.sh  npu_stress_test.sh  npu_test.sh

NPU frequency test script npu_freq_scaling.sh

usage()
{
    echo "Usage: npu_freq_scaling.sh [test_second] [every_freq_stay_second]"

0.000172 - 285

The content after Begin perf... shows the performance data of multiple model runs:
Each record shows the run number, the corresponding elapsed time (Elapse Time), and the frames per second (FPS). For example, 0: Elapse Time = 2.85ms, FPS = 351.12 means that during the first model inference run, it took a total of 2.85 milliseconds, and from this, it can be calculated that 351.12 frames of data can be processed per second (the FPS is calculated by dividing 1000 by the elapsed time for each run, and then converting the unit to frames per second).
The ---- Top5 ---- section presents the top 5 categories with the highest probabilities in the model inference output results, along with their corresponding probability values and category numbers:
0.935059 - 156 means that the model believes the input data (such as an image) is most likely to belong to category number 156, with a corresponding probability as high as 0.935059. This relatively high probability value indicates that the model has a relatively high confidence in this judgment.
The subsequent 0.057037 - 155, 0.003881 - 205, 0.003119 - 284, and 0.000172 - 285 list the category numbers and probability values of the second to fifth most probable categories respectively. These probability values decrease successively, indicating that the model's confidence in their belonging to the corresponding categories also gradually decreases.

GPU

Check GPU Utilization

console$ cat /sys/devices/platform/*gpu/utilisation

Example: Check the utilization in real-time
$ watch -n 1 'cat /sys/devices/platform/*gpu/utilisation'
Move the mouse or drag the window to check the GPU utilization to determine if hardware acceleration is working.
