[Atlas 200dk] Raspberry pi camera

Hi, dear !

Well I think you can try to set cameraFps_ = 5 when intialize camera if you want to use the Raspberry Pi HQ Camera firstly.
And then watch the sample if run successfully or not.

If OK that's fine. And If it runs failed, I think we can analyse the reason by detailed log.

The way to get the log is :
connect Atlas200DK
move to this folder: /var/log/npu/slog/host-0
remove old log files in this folder firstly, and run the sample again to generate the newest log file which we need.

And I hope you can provide the version info of your 200DK and virtual machine as well.

Is there a way I can access the libmedia_mini content?

Hello! Thank you for replying so fast!

My enviroment is:
Ubuntu 18.04
MindStudio 2.3.3
Ascend Toolkit 20.0.RC1
Atlas DDK 1.73.5.1.B050

I attempted setting the camera to 5fps but the sample still fails. The failure actually happens before setting this configuration parameters. It happens on QueryCameraStatus(), right after the LibMediaInit()

The log actually didn't inform more than the output log in MindStudio. I tried to edit the post to add atachments but all uploads failed. You can access them in this link to my onedrive folder: https://1drv.ms/u/s!Arb8y_A0WTjfcUCHnGWc5B5H92s?e=guM8Yy

One thing I noticed is that host-0 log pointed to a file "sdk/hi3559/osdrv/components/libmedia_mini/./common.c:153" which perhaps could indicate why does this media library cant find the camera?

I feel sorry that reply you so late for confirming some information.
I think this error means 200dk cannot support your Raspberry pi Camera HQ, because its camera driver is designed and doesn't support all cameras.Maybe you can ask post-sale to obtain specified camera.
