你说的对，我们现在还没有那么高的ADC精度的产品。
你的使用场景，动态范围很宽？ 用长短曝光时间来辅助解决可否？

@nian
12bit模式，相机是支持的。但是你现在只可以将其保存为文件，并手动转换为可以方便用软件读取的格式。你可以看一下这个文章part7，尤其是part7.5的部分

14bit这个，我们现在相机还不支持。sensor是有的，我们没有做这个格式。

@nian 不客气

@nian

@nian said in 有一些错误 ，大神们 请指教啊raspi5 +imx78:

但是veye_vbyone不能用 是不是可以忽视往下进行？

是的。
请更新一下最新的github上的media_setting_rpi5.sh，应该就可以解决你现在的问题。

@linoooooo
你好，fps参数是可以修改的。但是需要先停止取图。曝光时间是被限制到1/fps的。 你可以先设置合适的fps，然后在范围内进行曝光时间的修改。

在这个脚本中，带星号的命令，都是取图中写保护的。
你也可以参考寄存器清单中的part1.3来理解这个设置规则。

@fumyang 请问您用的是哪个相机模组？

1. The MV-MIPI-GMAX4002M model was missing on this page and has now been added. Both Jetpack 5.1 and 6.2 are supported. However, we currently only provide the 4-lane mode DTB for Orin NX and Orin Nano under JP6.2 mode, as only these two boards have official baseboards that expose the 4-lane interface.
3. You're right. Just place the order using that link. We will ship ADP-MV1-V2.
4. For Jetson Xavier NX, since the official baseboard only exposes 2 lanes, the DTB in our provided driver remains configured for 2-lane mode, which limits the maximum frame rate.
   As for Orin NX, there is no such restriction. You can refer to the 4 How to Use 4-Lane Modesection to enable 4-lane mode.
5. yes.
6. The MV series products feature ISP (Image Signal Processor) capabilities, including typical functions such as auto-exposure, LUT (Look-Up Table), and more.

@israel_bolo Actually, for the development of new projects, I would recommend using the V4L2 mode, which is the material from the link below.

@israel_bolo

May I ask which version of piOS you are currently using? The libdmipicam mode is only suitable for the 32-bit legacy mode of piOS.

@dragos You are welcome.

@dragos
I think the MIPI CSI interface on this board only exposes 2 lanes and uses a 15-pin connector.
Could you check your board to see if that's the case?

@dragos May I ask if the board you're using is an official NVIDIA development board or a compatible third-party board?

@linoooooo 你好，我们的相机内部isp流程是没有整帧缓存的，相机本身引入的delay是毫秒之内。
我觉得你这个延时主要是v4l2取图缓存和显示缓存的缘故。不过说实话SDL库我们不太懂，怎样优化需要您自己研究一下。
至于相机采集后，您这边程序直接导入算法的话，延迟肯定要比这种测量方法小的多。

@israel_bolo
I see some warnings, but no errors. could you please continue and see if it compiles?

@otca
The camera is now successfully probed, which confirms that both the I2C and the enable pin are functioning correctly.
The current issue indicates that the I2C control channel is working, but the MIPI CSI data channel is not. Please verify whether the MIPI CSI interface pin assignment on this carrier board matches that of the official Orin NX development board.
The Device Tree Source (DTS) should be adjusted accordingly to match the carrier board.

@stiwana Sorry, we do have this in mind, but no actual plans or projected time of completion at this time.

@阿坎德 你好，有进一步的结果吗？

@nkos
Please enter this directory and run ./make.sh.
mv_tools_rpi/sources

@阿坎德 看现象感觉是内存泄漏。这个demo现在基本用途上是客户做一下出图验证和聚焦。所以只是个简单的例子。回头我们会安排时间跟进一下。
