按文档安装V4L2驱动，出问题，看是看不到video0设备
-
- cat /boot/config.txt 看看最下面有没有veye327相关的一行。
- ls /lib/modules/$(uname -r)/kernel/drivers/media/i2c/ 看看最下面一行有没有veye327驱动。
- 检查硬件连接，有没有给摄像头供电？
- 执行i2cdetect -y -r 10看看能否probe到0x3b地址，也就是显示出摄像头。
- 尝试wiki上的gstreamer命令。

@veye_xumm said in 按文档安装V4L2驱动，出问题，看是看不到video0设备:
i2cdetect -y -r 10
还是老样子，dmesg | grep veye 看不见，video0也没法正常使用 -
@luchec 你试试i2c0能看到吗
i2cdetect -y -r 0
另外硬件接好了吗？
可否拍个连接细节图 -
@veye_xumm
用你们提供的那些不用v4l2的API都可以，就是这个V4L2就用不了 -
@luchec
感觉你可能装过几个型号，但是没有uninstall，去掉我标注的这两行试试。
另外试试i2cdetect -y -r 0 -

@luchec 验了一下，@tammojan 提供的这个release版本的确有点问题。 我会安排人跟进搞一下。需要几天时间，请关注github的更新。

@luchec (I'm tammojan.) I only tested the csimx307.ko , not the veye327. The CXIMX307 it seems to work for me. If there are problems with the drivers I'd be happy if you could find out!

@tj 不客气，谢谢你们提供的资源

@veye_xumm 好的，我去试一下

@veye_xumm 测了一下，

@luchec
这个版本的linux是用的i2c-10,你正常使用preview和预览就可以了。 -
@veye_xumm 好的
