@veye_xumm 这样啊，好的麻烦您了，我再跟公司里沟通一下

@nian 好的

@golden0514 你可以进一步将fps设置小，相应的最大曝光时间也会拉长。

@nian 不客气

@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？

@stiwana

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. You're right. Just place the order using that link. We will ship ADP-MV1-V2. 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. yes. The MV series products feature ISP (Image Signal Processor) capabilities, including typical functions such as auto-exposure, LUT (Look-Up Table), and more.

@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.

@dragos You are welcome.

@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。

@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？

@veye_xumm now it works, thanks

@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。

@megan
First of all, please go to the following link to update the driver of mvcam. The latest driver will set the lane number in the camera according to the configuration of the DTS.

https://github.com/veyeimaging/rk35xx_veye_bsp/tree/main/linux/drivers/kernel_v5.10

Secondly, the DTS needs to be configured according to your RK3588 board, and I can't do it directly for you. You can make analogies and modifications by referring to the DTS of the camera originally supported by your board.

@limengfei 可能是dts设置不正确。请根据你的硬件原理图正确设置dts。

@joe The RAW-MIPI-AR0234M is a MONO camera that has no color information and therefore does not support the UYVY data format. Please refer to this link below:

@veye_xumm 是的 非阻塞缓存后写图，已经解决了。抓拍的图像基本模拟一次就有一张抓拍，因为闪一次时间是1ms 所以只抓到一张也是合理的。

使用脚本可以，感谢
