CS-USB-IMX307 OpenCV 連續採集影像造成 USB disconnct

veye_xumm

@coolmitch
我今天安装了一个3.2.0版本的opencv，跑你之前给的例程不行。
安装4.5.2的版本，失败了。

coolmitch

@veye_xumm
我重寫一個 python3 程式給你。照理沒有一定要 4.5.2，但你可以試看看 https://qengineering.eu/install-opencv-4.5-on-jetson-nano.html
我是照這個步驟編譯的。編譯過程一定要把 swap 打開，不然虛擬記憶體會不夠用。

veye_xumm

@coolmitch
我也是按照这个步骤做的。但是cmake阶段报错了。

coolmitch

@veye_xumm cmake 可能需要重新安裝新版。
參考這個（我有點忘記更新 cmake 的程序了)

@coolmitch
请问你的cmake版本是？
我的是3.10.2

veye_xumm

@coolmitch
我更新了一下cmake，还是编译不过。
anyway，这事先放一放。
我现在改了一个版本的固件，用ffmpeg循环测试的方法，测试到6000+次数，还是稳定的。
请你也升级并老化测试一下：

@veye_xumm
cmake --version
cmake version 3.10.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).
我的也是 3.10.2
所以會不會是有什麼 dependent lib 沒有安裝完全？

coolmitch

@veye_xumm
升級後，開機看到這個

不過我還是讓他去跑著測試了...
今晚先用 python3 的程式跑跑看...

veye_xumm

@coolmitch
我这边老化一夜，已经运行38000+次数，现在还是稳定的。期待你的结果。

coolmitch

@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？

veye_xumm

@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。

coolmitch

@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...）

veye_xumm

@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

@veye_xumm
對了，在 CS-USB-IMX307 新版韌體更新後，插入主機時會出現以下訊息，請問那些 Failed to query (GET_DEF) UVC control ... 是否就是 driver 要去讀取 uvccamera 參數時讀不到的錯誤？

@coolmitch
这个就是对于uvc参数支持不完善所体现出来的。

veye_xumm

@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。

coolmitch

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。

veye_xumm

@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。

coolmitch

@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。
