@veye_xumm 嗨 根据您这边的回复，查看了文档，使用shell脚本可以设置曝光时间、对比度等，但是在文档中没有看到锐度的设置参数是什么，我查看了IMX307的介绍，是支持锐度设置的，这个锐度的设置参数什么？谢谢

@powerliusu
你的这几个操作并没有必然逻辑的相关性。

@powerliusu said in jetson nano 在移植核后无法再烧录镜像:

apt-mark hold

这个的作用是标记一下防止后面apt upgrade的时候把kernel也升级掉。本身不是必须的步骤，你可以先忽略掉它。

@powerliusu said in jetson nano 在移植核后无法再烧录镜像:

i2cdetect 总线1的10寄存器数值改了

这个命令的作用是检测某个i2cbus上存在哪些i2c设备，你用的是nanoa02,对应的i2cbus应该是6。 替换完成Image和dtb之后，重启，然后用i2cdetect -y -r 6作为辅助调试手段即可。

至于sd卡无法烧录，建议你格式化这个tf卡后再试一次，或者换个tf卡试一下。

整体上而言，步骤是：烧写标准系统-->更新Image和dtb-->系统重启-->检测状态。

@lym123 请尝试一下做如下修改：

@veye_xumm said in Please advise compatible mono camera:

Which functions of isp do you need, please?

Just AE,IS and crop, if there was a way to skip ISP, I'd do.
Other reqs would come up later, now I just can't start developing CV part.

@milank I suspect that the FFC cable is not connected well enough. You could try replacing the FFC cable with a new one, or re-plugging it.

Hello, for rockchip platform, we are now accessing the chip rk3566 RK3568 RK3588, etc. For the time being, there is no plan to access to rk3599.

The motherboard manufacturer of our choice is firefly, and provides the corresponding adapter board.
For details, you can refer to the following link. The driver on the rk35XX, which will help you to make the docking.

@nathan-sinclair said in using veye-mipi-327, unedited h264 video for display in html video element:

Just a query about whether it's possible to be sending the h264 video from the mipi-327 camera unedited, so that it can be displayed in a video element on a web page.
The way we are currently doing this, is using a library on the client side called jmuxer, which, through a websocket directly is able to display arducam cameras. Is there something similar with the mipi-327 camera as seen in libcamera-examples?

Sorry, we now only have a similar demo available in legacy mode via gstreamer.

@thn The possible reason is that there are other signals on the i2c bus, causing the camera to misjudge.
Is there any other device mounted on your i2c bus?

@veye_xumm Thanks for your reply. The IMX482 does indeed look very good for low light recordings!

@seyran с вашей командой тоже не работает, при создании буфера зависает, что может быть не верно ?

@radiohound As far as I know, sony's datasheet is only open to corporate customers who have signed an NDA.

I'd be interested if you find anything out about this. Arducam has their own imx462 camera, but I notice it has a lot less ic chips on the back of it. So not sure their driver is going to help, or if they even have the ability to take a long exposure.

part3.2--->part1.2。

@yang 已经编译过的版本我们放在github的release中了。我看来一下现在没有对应你kernel版本的编译好的驱动。
参考github的readme或者
http://wiki.veye.cc/index.php/Build_drivers_from_source_for_rpi/zh
从源码编译一下吧！

@chjchoi I tried to send you an email , but it bounced back. Please confirm this email address.

@stevenyang
根据part1.3,现在的确没有这个版本。

建议你将xavier主板升级，或者自己将4.6.1版本上的驱动移植回4.5.1都是可以的。

@dmmoskalev Great!

@veye_xumm 好的 谢谢 我再重新搞一下

@jyang

视频流模式帧率
MV-MIPI-SC130M : 1280 × 1024@108fps 这个我们在进行升级中，谋求更高的帧率。
RAW-MIPI-SC132M: 1080 × 1280@120fps 触发模式帧率
现在这两款sensor处理外触发，不够完美。 需要顺序进行曝光+传输，整体完成之后才能处理下一个触发信号。具体可以看一下这个链接，2.4.2。
举个例子，对于MV-MIPI-SC130M,配置为108帧的时候，每一帧的传输时间是1000000/108=9260us。如果你配置每一帧的曝光时间是10ms，那么，一个完整触发帧周期是10+9.26=19.26ms。则最大触发帧率是1000/19.26=51.92帧/秒。

@harryxiong 暂无此计划。 单帧hdr效果不够好。
