Linux 如何在iMX8QXP上运行OV5647_mipi,linux,linux-kernel,yocto,imx6,imx7,Linux,Linux Kernel,Yocto,Imx6,Imx7,您好，我有iMX8QXP工具包，我想从ov5647相机获取流 DISTRO=fsl imx wayland 我的ov5647相机的pin连接到： MIPI\U CSI0\U ACM\U MCLK\U OUT MIPI\U CSI0\U MCLK\U OUT ALT0 MIPI_CSI0_CKN MIPI_CSI0_CLK_N ALT0 MIPI_CSI0_CKP MIPI_CSI0_CLK_P ALT0 MIPI_CSI0_DN0 MIPI_CSI0_数据0_N ALT0 MIPI_CSI0_D

您好，我有iMX8QXP工具包，我想从ov5647相机获取流

DISTRO=fsl imx wayland

我的ov5647相机的pin连接到：

MIPI\U CSI0\U ACM\U MCLK\U OUT MIPI\U CSI0\U MCLK\U OUT ALT0

MIPI_CSI0_CKN MIPI_CSI0_CLK_N ALT0 MIPI_CSI0_CKP MIPI_CSI0_CLK_P ALT0 MIPI_CSI0_DN0 MIPI_CSI0_数据0_N ALT0 MIPI_CSI0_DN1 MIPI_CSI0_数据1_N ALT0 MIPI_CSI0_DN2 MIPI_CSI0_数据2_N ALT0

MIPI_CSI0_DN3 MIPI_CSI0_数据3_N ALT0 MIPI_CSI0_DP0 MIPI_CSI0_数据0_P ALT0 MIPI_CSI0_DP1 MIPI_CSI0_数据1_P ALT0 MIPI_CSI0_DP2 MIPI_CSI0_数据2_P ALT0 MIPI_CSI0_DP3 MIPI_CSI0_数据3_P ALT0

但I2C引脚未连接。有问题吗？我可以通过i2c在没有初始化的情况下从相机获取数据吗

因此，我在./include/dt bindings/pinctrl/pads-imx8qxp.h中找不到这些管脚（带有焊盘信号名称），如果我将这些管脚写入焊盘格式，我将得到错误，而不是写入MIPI_CSI0_ACM_MCLK_OUT。我想这个别针是专用的，我不能多路复用。我可以直接使用，无需更改scfw

因此，我的关于mipi csi摄像头的dts文件：

我尝试了video12和video13通过lvds用以下命令打开摄像头：
