i.MX8 MQ 使用ov5640 sensor ，无法修改 图像输出格式pixelformat和分辨率

[zhouqi]

Dear all:

    本人在使用imx8mq mipi csi2接口采集图像，sensor是 ov5640相机，使用的bsp是4.14.98-imx_4.14.98_2.0.0_ga，编写测试程序测试yuyv 640*480图像输出是正常，但是除此之外，其他所有的分辨率和图像格式修改后都无法正常输出。fmtdesc显示目前只支持yuyv的格式，我不知道是哪里出了问题。

    关于ov5640的设备树的配置如下：

ov5640_mipi: ov5640_mipi@3c {
compatible = "ovti,ov5640_mipi";
reg = <0x3c>;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_csi1_pwn>, <&pinctrl_csi1_rst>;
clocks = <&clk IMX8MQ_CLK_CLKO2>;
clock-names = "csi_mclk";
assigned-clocks = <&clk IMX8MQ_CLK_CLKO2>;
assigned-clock-parents = <&clk IMX8MQ_SYS2_PLL_200M>;
assigned-clock-rates = <0>, <20000000>;
csi_id = <0>;
pwn-gpios = <&gpio1 3 GPIO_ACTIVE_HIGH>;
rst-gpios = <&gpio1 4 GPIO_ACTIVE_LOW>;
mclk = <20000000>;
mclk_source = <0>;
port {
ov5640_mipi1_ep: endpoint {
remote-endpoint = <&mipi1_sensor_ep>;
};
};
};

下面是我的一些调试打印：
[ OK ] crop set
[ OK ] crop get 2nd: crop.type =1 crop.get left=0, top=0, width=0, height=0

[ OK ] parm set
[ OK ] parm get 2nd: type=1, capability=4097, capturemode=0, extendedmode=0, readbuffers=0, numerator=1, denominator=30

[ OK ] fmtdesc: Support format:
0.YUYV 4:2:2

[ ERROR ] /dev/video0 does not support fmt: 1st get, ret = -1
[ ERROR ] /dev/video0 does not support fmt: set, ret = -1

[ end ] return ret = -6

ov5640的驱动代码如附件：

我在probe函数中，做了如下修改，也没用，输出依然是yuyv格式

#if 0
//base
sensor->pix.pixelformat = V4L2_PIX_FMT_YUYV;
sensor->pix.width = 640;
sensor->pix.height = 480;
#else
//changed
sensor->pix.pixelformat = V4L2_PIX_FMT_RGB24;
sensor->pix.width = 640;
sensor->pix.height = 480;
#endif

请大家帮我看看哪里有问题。

谢谢~~~

Hi zhou

我看了一下驱动程序，ov5640mipi_v2的参数设置是通过init_device函数里的

ret = ov5640_init_mode(sensor, frame_rate, ov5640_mode_INIT,
			       ov5640_mode_INIT);

其中传入的参数是ov的默认模式，你可以参考ov5640_init_mode函数里的以下部分设置你想要的参数并下载进去。我们支持的参数都在c文件开头定义了。

if (mode == ov5640_mode_INIT) {
		pModeSetting = ov5640_init_setting_30fps_VGA;
		ArySize = ARRAY_SIZE(ov5640_init_setting_30fps_VGA);

		sensor->pix.width = 640;
		sensor->pix.height = 480;
		retval = ov5640_download_firmware(sensor, pModeSetting,
						  ArySize);
		if (retval < 0)
			goto err;

		pModeSetting = ov5640_setting_30fps_VGA_640_480;
		ArySize = ARRAY_SIZE(ov5640_setting_30fps_VGA_640_480);
		retval = ov5640_download_firmware(sensor, pModeSetting,
						  ArySize);

Hi zhiming

     thank you very much for your answer.

    我的问题依然未解决，依然无法让相机输出RGB格式的图像。

    我通过ioctl(fd, VIDIOC_S_FMT, &fmt) 让相机输出RGB565格式的图像，但是ioctl返回失败，

    我也在下面的初始化寄存器数组中，修改0x4300、0x501f的寄存器值后也依然无法输出RGB565格式。

    麻烦帮我看一下，这是怎么回事或者能提供排查方法嘛，现在我没有任何头绪，万分感谢

Hi zhou,

你试一下这个帖子。

Hi zhiming

   很感谢你快速的回复，也很抱歉现在才回复你。

   我认真的看了那篇帖子，也试了论坛里很多关于RGB相关的配置，在ipu_bg_overlay_sdc.c， mx6s_capture.c， ov5640_mipi_v2.c, mxc_mipi_csi.c中做了相应的RGB格式配置的添加，从添加的内核打印来看，的确成功地输出了RGB格式的内容，但是当我把rgb转成BMP格式，显示到屏幕发现图片有很多问题，我不知道是哪里配置有问题，生成的图片已经上传附件。修改的部分也贴在下面。
