@lizi 你好，我们这个相机本身是黑白的，只有一个通道。 驱动输出的数据也是单通道的。 你的意思是进入opencv现在是三通道模式的？ 不好意思，这个我们对opencv的确不太熟，这方面需要再研究。

@veye_xumm 好的，感谢解答。

@liuyue 已私信。

@etale_cohomology said in How to set exposure for IMX-287M?:

It turns out you must manually select the I2C bus number (I also enabled I2C on raspi-config). Since I'm using CAM0 on RPI5, the bus is 6. Example:
./mv_mipi_i2c.sh -r -f manufacturer -b 6
This works.

Yes

@lizi 好的。

@veye_xumm 好的，感谢

@canglin 默认是discontinues模式。

@veye_xumm 谢谢，原来它只能写成/dev/v4l-subdev2

@vaa said in New Raspberry pi 5 support:

@veye_xumm
In case I try to set pixel_format to any other value is cause VIDIOC_STREAMON fail. I suppose this is a bug in the driver.
Some other applications like gstreamer only set pixel_format if you directly point to do this, this is why it works, but many others (e.g. trying to set default pixel_format) are not.

Will you going to fix the issue?

@veye_xumm 好的，谢谢

@natzguk pls try this:

@liliant 一般来说，能出图，i2c是通的；那么摄像头应该没有坏，控制参数也应该生效才对。

@lll 是的。本质上是修改对应的寄存器即可。

@newleaf You are welcome.

@veye_xumm For anyone else. This works perfectly. Note that when recompiling on 64-bit Pi, the following warning is produced. It still builds. Just copy the outputs to bin and the scripts work fine.

./make.sh i2c_read.c: In function ‘main’: i2c_read.c:112:35: warning: passing argument 4 of ‘i2c_rd’ from incompatible pointer type [-Wincompatible-pointer-types] 112 | i2c_rd(fd, device_addr,reg_addr, &value, num); | ^~~~~~ | | | unsigned char (*)[512] i2c_read.c:20:68: note: expected ‘unsigned char *’ but argument is of type ‘unsigned char (*)[512]’ 20 | static int i2c_rd(int fd, uint8_t i2c_addr, uint16_t reg, uint8_t *values, uint32_t n)

@mjyc
./media_setting_rpi5.sh XXX只有这个是必须要执行的。
上电之后，执行一次。

@yd 已添加，请通过。

@veye_xumm 我换块板子试试吧

@lin 你的图片我看不到。但是根据你的描述，似乎没有更新dtb。
另外我们提供了一个现成的镜像，在这个链接：
