2.4.4 Configuration Verification

After configuration, verify the system setup:

# 检查可用的视频设备
ls /dev/video*

# 列出video0支持的格式
v4l2-ctl --device /dev/video0 --list-formats-ext

# 预期输出应显示:
# [0]: 'RGGB' (8-bit Bayer RGRG/GBGB)
#      Size: Discrete 4096x32
#      Interval: Discrete 0.033s (30.000 fps)
#      Size: Discrete 4096x1536
#      Interval: Discrete 0.033s (30.000 fps)
#      ...

# 检查媒体控制器拓扑
media-ctl -p

# 验证CSI接口
dmesg | grep -i csi

# 测试数据捕获
v4l2-ctl -d /dev/video0 --stream-mmap
# 当雷达传输时应无错误地流式传输
