突然想起来之前在这里发过这个问题，现在已经解决了。

在内核配置.config中将CONFIG_CCI关闭，CONFIG_CCI_TO_TWI打开即可使用普通IIC，之前看文档不够仔细，现在直接将sensor1的SCL和SDA接到普通IIC就可以了。

# CONFIG_CCI is not set
CONFIG_CCI_TO_TWI=y

如图，芯片dual lvds输出最高只支持1920x1080

目前想要点一块1920x1200的屏幕，dclk时钟要求要152MHz是我计算了一下lcd_dclk_freq是可以满足屏幕手册时钟时钟要求的。

请问这样超规格点屏幕会出现什么问题呢？

请问sensor的iic接口是一定要接到mcsi或者ncsi接口上吗，能接到普通iic上吗？

如果是下面这种共用cci的接法是否可行呢，我用这种接法配置的时候mipi那路摄像头会出现select timeout

我需要利用T5的usb0输出视频图像，脚本参考run_otg，应用层demo来自uvc-gadget，应用层启动指令为./uvc-gadget -i /root/images.jpg -f 1 -s 1 -r 1。
在设备树中CONFIG_USB_F_UVC和CONFIG_USB_LIBCOMPOSITE都已经打开，接入Ubuntu之后也能识别出video设备，但是无法通过VLC或者cheese打开,想问下大佬们这是什么问题导致的，是应用层还是脚本的问题。几个打印信息的报错都找过，没能找到解决方法。。。

在ubuntu中使用v4l-utils查看打印信息如下

你好，请问这个问题有解决方法了吗，我也遇到了这个问题，参考的也是《Linux_USB_开发指南》,用VLC打开之后报错

Flork

@whycan
谢谢晕哥！lvds能显示了

我还想问下如果我想要lvds输出标准74.25MHz的720P30该怎么配置呢

目前是第一路都直接显示绿屏，第二路还没有测试，想先把lvds0调通

Flork

使用的是T507芯片，利用PD0-PD9作为第一路LVDS输出，PD10-PD19作为lvds的第二路输出。

上电之后显示绿屏

lcd0 与 lcd1配置除了后面的pin都一样

是需要更改disp驱动的内容吗
