@veye_xumm said in IMX462+树莓派zero 2w，无法正常控制曝光参数去拍照: @若兮鱼 你使用的是驱动模式，不需要调用camera_i2c_config 核心问题是i2c_write这个可执行文件无法执行。可能是发布的release版本，与你的系统在可执行文件格式方面兼容性不好。你可以进入source目录下，编译一下。然后重新执行。 首先可以通过读取devid来确认你的i2c命令通道，veye_mipi_i2c.sh脚本是否正常了。 你好，谢谢，重新编译source目录里的文件后都正常了。问题已解决。

@veye_xumm it is resolved now, the image is shown. Before with the steps on the forum the .dtbo file was also missing, I copied it from another folder and it didn't work. The right and supported way of installing drivers is very confusing, I tried installing by wiki guide and then compiling locally (github), since it didn't work. Thank you for your patience.

@nian 不客气

@veye_xumm Thanks! I'll read and reinstall the SO. Hopefully, I'll be able to show if the problem is resolved in the next few days.

@veye_xumm Thanks my problem is solved.

@opti Please check this: https://github.com/veyeimaging/raspberrypi_v4l2/releases/tag/v1.22

@chenhaoyu 这个实现不了，树莓派只有两个mipi口。

@sqf121 这个问题已经解决，请参考一下github上的更新。 https://github.com/veyeimaging/raspberrypi_v4l2

已解决，请访问 https://forum.veye.cc/topic/581/树莓派4b-imx462-ffmpeg-meteor-master-ai-流星监控方案-不断更新

@veye_xumm 楼主，我用的这个微雪的树莓派CM4扩展板， https://www.waveshare.net/wiki/CM4-IO-BASE-A 能麻烦帮我看看么？

@veye_xumm 好的，已经解决了感谢

@natzguk Raspberry Pi 5 is special, its i2c bus is 4 and 6. meanwhile, Raspberry Pi need to configure the parameters in advance, please refer to this link below: https://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi#Raspberry_Pi_5_Setting

@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 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)

@etale_cohomology [image: 1702967744898-080d6fcb-12e7-4338-800a-b7ef90734db4-image.png] I think the FFC cable direction is wrong here.

@natzguk I believe the code is compatible. You can refer to the following link and try compiling it yourself: https://wiki.veye.cc/index.php/Build_drivers_from_source_for_rpi
