找不到UVC

2024-03-06 10:20

我跟着这篇教程的步骤走,当到内核这一步骤时,发现并没有名为UVC的选项
我尝试在内核配置:
cd <SDK目录>/sysdrv/source/kernel
cp ./arch/arm/configs/luckfox_rv1106_linux_defconfig .config
make ARCH=arm menuconfig

和buildroot:
cd <SDK 目录>/sysdrv/source/buildroot/buildroot-2023.02.6/
make luckfox_pico_defconfig
make menuconfig

: 在buildroot搜UVC出来的

寻找,但是均未找到
于是当我用串口登录时,将usb摄像头接入LuckfoxPico时报错:

: 串口报错

请问有没有什么解决办法?为什么?

您好，很抱歉我们的 wiki 对 kernel 的设置没有描述清楚，在 kernel 设置的详细步骤为
1. 使用 / 搜索关键字

2. 选择序号为 2 的索引

3. 按 y 确认将 Media USB Adapters 编译进内核

4. 回车打开 Media USB Adapters 子目录

buildroot 正常打开 fswebcam 和 libv4l2 即可。

我将分辨率改为640*480之后,fswebcam保存成功了.但是我的摄像头本身是支持1080p的,而我fswebcam想要拍1080p的时候貌似会出现内存不足的现象,导致无线重启.
我想知道为什么分辨率为1920*1080的时候会这样,如何解决,以及如下报错是由什么原因造成的,即:
v4l2-ctl --list-devices的时候出现:

您好，使用 fswebcam 捕获 1080p 的图像如果因为内存不足而失败可以尝试：
1.在设置文件夹 <Luckfox-pico SDK>/project/cfg/BoardConfig_IPC/ 中将对应配置文件 BoardConfig-XXX.mk 中修改 RK_BOOTARGS_CMA_SIZE 项，降低数值减少内存对cma的分配；

2.同时在 luckfox-pico 启动时使用 killall rkipc 关闭 csi 摄像头的开机程序，减少内存占用；
注意：由于 UVC 设备种类较多，无法确实是否是因为内存不足而导致反复重启，无法完全排除硬件问题。

使用 v4l2-ctl --list-devices 内核信息报错的原因是镜像中默认设置了csi 摄像头的设备树和驱动，但是摄像头没有物理上的连接，报错信息可以忽略。

启动时出现的 usb0 默认是作为虚拟网卡使用，在 /etc/init.d/S90usb0config 启动脚本中对其 ip 进行了设置，而 usb 为了接入 uvc 设备设置为 usb host 模型，原本针对 usb 网卡的控制脚本无法正常运行就发出提示信息，您可以尝试注释相依的脚本来屏蔽相应的错误信息。
