# 遍历所有USB设备，输出其传输速度 Traverse all USB devices and output their transfer speed
for device in $(ls /sys/bus/usb/devices/); do
    if [ -f "/sys/bus/usb/devices/$device/speed" ]; then
        speed=$(cat /sys/bus/usb/devices/$device/speed)

Transmission Performance Test

 Transmission speed is the core difference between USB2.0

and USB3.0

. The theoretical speed of USB2.0 is 480Mbps, while that of USB3.0 is 5Gbps. Two commonly used test methods are provided below, applicable to USB storage devices and network USB devices respectively.

1. Simple Test: dd Command

 The dd command can quickly test read and write speeds for preliminary verification. Mount the USB device first before testing.
 1.1 Mount the USB device:

1. 简易测试：dd 命令

dd命令可快速测试读写速率，适合初步验证，测试时需先挂载 USB 设备。

# 假设通过lsblk确认USB设备节点为Assume the USB device node is /dev/sda1，创建挂载点并挂载sda1 confirmed by lsblk, create mount point and mount
mkdir -p /mnt/usb
mount /dev/sda1 /mnt/usb

 1 1.2 . 测试顺序写速率：Test sequential write speed:

# 写入1GB零数据到USB设备，绕过缓存确保结果真实 Write 1GB zero data to the USB device, bypass cache to ensure real results
dd if=/dev/zero of=/mnt/usb/testfile bs=1M count=1024 conv=sync oflag=direct

 1.3.测试顺序读速率：Test sequential read speed:

# 读取USB设备中的测试文件并丢弃，测试读取速度 Read the test file from the USB device and discard it to test the read speed
dd if=/mnt/usb/testfile of=/dev/null bs=1M iflag=direct

 1.4.测试后清理临时文件：Clean up temporary files after testing：

rm /mnt/usb/testfile

 结果说明：命令执行完毕后会显示传输时间和速率，USB2.0 实际写速率通常在 10 - 30MB/s，USB3.0 实际写速率通常在 50 - 150MB/s（受设备本身性能影响）。

fio工具支持复杂的 IO 场景测试，结果更全面，适合深度性能评估。

Result Description: After the command is executed, the transfer time and speed will be displayed.

• The actual write speed of USB 2.0 is usually 10 - 30 MB/s.

Input Video Stream Playback Test

1.

Execute video playback command:

# 切换到具备图形显示权限的用户Switch to the user with graphical display permissions
su - blueberry

# 配置显示环境变量（指定主屏输出），通过 GStreamer 播放 HDMI 输入视频流 Configure display environment variable (specify main screen output), play HDMI input video stream via GStreamer
gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! autovideosink

2. 执行结果验证Execution Result Verification

Setting pipeline to PAUSED ...       # 管道状态：暂停中Pipeline status: Pausing
Using mplane plugin for capture      # 采集插件：使用mplane（多平面）模式 Capture plugin: Using mplane (multi-planar) mode
Pipeline is live and does not need PREROLL ...  # 管道状态：已激活，无需预滚动 Pipeline status: Active, no preroll required
Pipeline is PREROLLED ...            # 管道状态：完成预滚动（数据已就绪） Pipeline status: Preroll completed (data ready)
Setting pipeline to PLAYING ...      # Pipeline status: 管道状态：播放中Playing
New clock: GstSystemClock            # 时钟初始化：使用系统时钟同步

输出解读：

每行日志对应 GStreamer 管道的启动流程状态，无报错信息说明：

1. 视频采集插件（mplane）加载成功；
2. 管道完成初始化、激活、预滚动，可正常开始视频流传输；
3. 时钟同步组件（GstSystemClock）正常工作，为视频流提供时间基准。

显示屏效果（如下图）：

开发板连接的显示屏弹出视频播放窗口，窗口内实时显示 HDMI 信号源输出的画面（如笔记本桌面、摄像头画面等），画面无花屏、卡顿、黑屏即为测试通过。

4.异常排查说明

 Clock initialization: Synchronized with system clock

Output Interpretation

Each log line corresponds to the startup status of the GStreamer pipeline. The absence of error messages indicates:

• The video capture plugin (mplane) is loaded successfully.
• The pipeline completes initialization, activation and preroll, and video stream transmission works properly.
• The clock synchronization component (GstSystemClock) runs normally and provides time reference for the video stream.

Display Performance

A playback window pops up on the monitor connected to the development board, showing real-time images from the HDMI signal source (such as laptop desktop or camera view). The test is passed if there is no screen distortion, stuttering or black screen.

Based on the hard decoding tool information of the Rockchip MPP (Media Process Platform) framework:

Test Steps:2.测试步骤：
 2.1.准备测试视频： Prepare test videos:

#1.本地测试视频路径：
 Local test video path:C:\Users\Administrator\Desktop\test_video\4K_60fps.mp4

# 2.通过 ADB 将视频推送至开发板：#2. Push the video to the development board via ADB:

 2.3.测试验证要点

• 视频播放状态：需无花屏、绿屏、卡顿等异常现象；
• 日志信息：终端输出中不得出现decode error、Resource not found、pipeline doesn't want to preroll等报错，需呈现正常启动流程（示例如下）；
• 显示效果：执行播放命令后，显示界面应呈现完整、清晰的视频画面（无解码异常导致的画面畸变、色彩失真）。

日志信息正常输出示例（说明）

2.3 Test Verification Points

 Video playback status: No abnormalities such as screen tearing, green screen, or stuttering shall occur;
 Log information: No errors including decode error, Resource not found, or pipeline doesn't want to preroll shall appear in the terminal output. A normal startup process shall be displayed (example shown below);
 Display effect: After executing the playback command, the display interface shall present a complete and clear video image (no image distortion or color distortion caused by decoding exceptions).
 
Example of normal log output (description)

2. 触发音频输入：对着 MIC 说话 / 播放声音；
3. 验证效果：从音频输出设备（扬声器 / 耳机）能实时听到采集的声音，无杂音、卡顿、延迟（<200ms）即为测试通过；
4. 停止测试：执行kill %1（后台任务编号）终止实时采集。

*注意事项

• 若执行报错Device or resource busy：先执行killall arecord aplay关闭占用音频设备的进程，再重新测试；
• 若无声音：检查-D参数的设备编号（通过arecord -l/aplay -l确认正确的输入 / 输出设备）；
• 若杂音较大：将-c 2改为-c 1（单声道），或调整采样率为44100。
• 系统音频输入通道配置：打开系统声音设置，切换到「Input Devices」（输入设备）标签页，在设备对应的「Port」下拉选项中，选择「Internal Microphone」（内置麦克风），确保音频输入通道已正确启用。

Test Operations and Result Verification

Execute Command: Enter the above command in the terminal and press Enter.
 Trigger Audio Input: Speak into the MIC or play audio.
 Verify Effect: Real‑time captured sound can be heard from audio output devices (speakers/headphones). The test passes if there is no noise, stuttering or delay (<200 ms).
 Stop Test: Run kill %1 (background task ID) to terminate real‑time capture.

Notes

• If Device or resource busy appears: Run killall arecord aplay to release occupied audio devices, then retry the test.
• No sound output: Verify the device number of the -D parameter via arecord -l and aplay -l.
• Excessive noise: Change -c 2 to -c 1 for mono mode, or set the sample rate to 44100.
• System audio input configuration: Open system sound settings and go to the Input Devices tab. Select Internal Microphone from the Port drop-down list of the target device to enable the audio input channel properly.

systemctl status quectel.service

预期结果

服务状态显示为 Expected Result
 The service status shows active (running).

3.设置开机自启Configure Auto-Start

# 配置服务开机自启 Enable service auto-start on boot
systemctl enable quectel.service

# 验证自启配置

# Verify auto-start setting
systemctl is-enabled quectel.service

预期结果

自启配置返回 enabledExpected Result
 The command returns enabled.

4. 重启验证Reboot Verification

# 重启设备Reboot the device
reboot

# 重启后检查服务状态 Check service status after reboot
systemctl status quectel.service

预期结果

Expected Result
 The service runs automatically after reboot with status active (running).

5. 网络连通性测试Network Connectivity Test

# 检查4G模块网络接口（以eth0为例，实际需根据模块接口调整）Check 4G network interface (take eth0 as example, adjust according to actual interface)
ifconfig -a

# 测试网络连通性（ping公网地址） Test network connectivity by pinging public address
ping -c 5 8.8.8.8

预期结果

4G网络接口正常获取 IP；

Expected Result

• The 4G interface obtains a valid IP address normally.
• Ping test succeeds with no packet loss, sample output as below:

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=109 time=60 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=109 time=60 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=109 time=60 ms
64 bytes from 8.8.8.8: icmp_seq=4 ttl=109 time=60 ms
64 bytes from 8.8.8.8: icmp_seq=5 ttl=109 time=60 ms

SIM Card Function Verification

1. 测试准备

硬件：已完成测试的 4G 模块、插入目标 4G SIM 卡的设备；

Test Preparation

• Hardware: Fully tested 4G module and device with target 4G SIM card inserted.
• System: Ensure quectel.service is in active (running)

• state.

2.

SIM Card Network Status

# 步骤1：查看wwan0接口的链路状态（确认接口是否激活） Step 1: Check link status of wwan0 interface
ip link show wwan0

# 步骤2：查看wwan0的IP地址信息（确认网络是否获取到地址） Step 2: Check IP address of wwan0 interface
ip addr show wwan0

# 步骤3：测试SIM网络的外部连通性（指定从wwan0接口发起请求） Step 3: Test external network connectivity via wwan0
ping -c 4 -I wwan0 www.baidu.com

3. 结果说明Result Description步骤 1 输出中，若wwan0状态为

• Step 1: Status UP,LOWER_UP

步骤 2 输出中，若wwan0存在inet开头的 IP 地址，说明网络已成功分配地址；

• means the interface is activated.
• Step 2: An address starting with inet indicates the interface has obtained an IP address successfully.
• Step 3: Output starting with

• 64 bytes from xxx.xxx.xxx.xxx

• means the SIM network works normally.
