@veye_xumm Sorry for the late reply. Thank you for the new code! It seems to work partially in the rpi5 standard OS. I was able to compile the read and write files, and some commands work while others don't. The new mgain is stuck at zero, so if i use new exp mode i can set the shutter speed with new mshutter, but not the new mgain, despite changing it returns zero when i probe with the -r parameter. so using the new exp mode i only get a black image. the old mshutter works and i was able go get up to 1 second exposure per frame in streaming mode but the capture mode and capture command don't seem to work. Also i would like to have it work in the rpi archlinux OS that i use for astronomy. The veyecam2m driver works and i get video in the archlinux OS, but i wasn't able to compile the i2c read and write in that system.

@mk No such plan, this cannot be supported. Sorry.

Why not use Again 27,and Dgain 5? Thanks I will try and let you know.

@veye_xumm As the time is too long and there is no further feedback from the customer, I will mark this post as resolved.

@veye_xumm I understood that the synchronization signal is very accurate in an environment close to hardware. We will check the details from time to time.

@wqeeqweqwwccsd 当然是支持的。你可以看这篇文章 6.3 6.4两个部分。 http://wiki.veye.cc/index.php/FPD_LINK_III_for_Jetson/zh 其中，6.4 xavier的典型案例就有实现了同一颗954连接的两路视频的同步。

@tj You are welcome.

@veye_xumm 好的非常感谢，这个是编译动态库 用于python代码调用时使用的。就是那个SDK使用方法

@eledog 我们装了一个你用的lite版本，运行是没有问题的。 [image: 1623146723636-9ecdb20e-ebc2-49f8-8719-e16be7cff655-image.png] 你用的硬件是4GB版本，我们的是2GB版本。 我这没法重现的情况下，你可以尝试103-123行进行逐行注释来找一下原因。 [image: 1623146803776-bb570ba3-c8aa-4d0a-828b-a582d8b0222e-image.png]

@veye_xumm 由于时间太久了,客户没有进一步的反馈,我会把这个帖子标记为已解决.

@fabricio-borges This question has been asked for a long time and the status has not been updated. I will mark the status as solved, so you can follow up again if needed, or just open the question.

@vvxy 当然，327型号只支持1080p这个模式。 具体可以看我们wiki上的手册。

@jdx-jdx 是的。probe成功才会生成video节点。

@veye_xumm Ok

@veye_xumm Okay. Anyway Thank you.

@veye_xumm I was just looking at the i2c program. Call this resolved.

@veye_xumm 好的 谢谢 我再重新搞一下

@lyj 我说的这个buffer不是camera里面的buffer，而是jetson主板上为了接收图像而创建的buffer。 不能设置为1，需要有一定的冗余才好。

@dufuwei 不好意思，我们这个无法绕过ISP模块。也不能提供完整的原理图。

@antony You've made a very accurate analysis and testing, which is admirable. For this camera model, to save space, we use a double-sided contact connector, which indeed has caused some issues. We are planning to improve this module by replacing it with a 22-pin single-sided contact connector. I, together with our hardware colleagues, conducted an analysis, and the results align with your test findings. After reconnecting the FFC cable correctly following a reversal, the sensor's registers and error codes did not indicate a damaged state for the camera. [image: 1702970334043-0cc7b86d-d1f6-4833-b373-dc0dc445c5ed-f5b019a3f2a6617992ded7348331e2b.png] In the case of reversed power connection, the pins that are actually damaged are CON_CS_D1P and CON_CSI_CLKP. Unfortunately, this issue cannot be detected through software.
