SOLVED CS-USB-IMX307 OpenCV 連續採集影像造成 USB disconnct
-
@veye_xumm 我昨晚也跑了 22000+ 次，這樣應該就過了。所以是什麼原因造成的？
-
@coolmitch
应该是我这边程序在处理close的时候，对资源的释放上有逻辑不完善的地方。 希望你后面也继续测试观察吧。嵌入式端控制frequency的问题，我再研究一下。 -
@veye_xumm 瞭解。昨晚的還繼續在跑。我今天會做另一個測試站雙重測試。uvccamera 的參數看有沒有辦法讓有支援的都給出來，這樣在 linux 這邊會比較好處理（之前用 python 的那個 fourcc 的處理方式，因為沒有完整 uvc 的參數，搞了很久才找到那個怪方法...）
-
@coolmitch
这个涉及到的改动太大了。暂时做不了所有参数都支持。现在我们只能是把摄像头默认参数调到最好。
另外就是你说的frequency hz设置的问题，需要解决一下。 -

@coolmitch
这个就是对于uvc参数支持不完善所体现出来的。 -
@coolmitch
我查了一下 powerhz 这个选项，应该是UVC control 5，这个是支持的。
至于为何v4l2-ctl报错，暂时还不清楚。 -
不好的消息
執行 29525 次之後，再度發生一樣的狀況。不過至少不是 6000 次斷。 -
@coolmitch
(⊙﹏⊙)
建议你暂时先设计一个机制，遇到问题时，或者定时，将jetson重启一下。
我觉得jetson重启的时候，usb接口会有断电重新上电的操作（需要验证），可以将系统整个从错误状态中恢复。 -
@veye_xumm 我可以試試看每天夜間定時重啟看看。但已知的狀況是，當 disconnect 發生時，重啟 jetson nano 是無效的（不斷電）。目前的硬體機制沒辦法讓他斷電重啟。
-
@veye_xumm 已確認下 reboot 指令時 usb 不會斷電。
-
@coolmitch
你好，不知你的jetson nano是哪个版本。
我查了一下官方的nano devkit的底板原理图，以及nvidia的论坛，这个usb的power应该是可控的。
以下帖子作为参考。
https://forums.developer.nvidia.com/t/usb-power-control/79037 -
@veye_xumm 這篇我有看過，當時看它是對 usb hub 下命令，所以我就沒去試了。其實我的機器不是開發板，是用 nvidia computer module 做的機器。我也會問看看主機板供應商有沒有辦法（之前問過是說不行）。還要再麻煩你幫我看看有沒有辦法不斷電讓它連續運行（雖然目前有大幅度進步，但仍然久了還是會斷線）或是說有什麼 uvc 的命令可以讓它自動 reset 重啟我這邊也可以配合來下相對應的命令。
-
@coolmitch
你好，我查了一下uvc标准里面应该是没有reboot功能的。https://askubuntu.com/questions/645/how-do-you-reset-a-usb-device-from-the-command-line
上面这个链接，有一个reset usb的功能，不知是否能解决问题？如果搞不定，我可以给你专门做一个reboot 摄像头的cmd，用通用的uvc命令来实现。 比如说： 设置色度为0，则表示命令摄像头重启。
-
@veye_xumm 哈，這招我也早用過了，無效。
-
@veye_xumm
色度是指這個嗎？我可以試看看
hue 0x00980903 (int) : min=0 max=100 step=1 default=50 value=50
我用 v4l2-ctl 下
v4l2-ctl -d /dev/video0 --set-ctrl=hue=0
可是它還是顯示 value=50 -
@coolmitch 我用另一個別的廠牌的 uvc camera 可以這樣設定。
v4l2-ctl -d /dev/video1 --all

@coolmitch
我的意思是，冒用这个协议。 这个需要单独给你做一个版本的固件升级包，现在的版本当然是不支持了。 -
@veye_xumm 我的意思是，就目前的版本，我也無法去設定他的值（但在其他的攝像頭可以設定）。所以是否改的冒用的版本也不能用？
-
@coolmitch
当然，会可以。
