bring up ar0544 with 8mp isp on android os

[bingyan]

Hi  @zoey_li 

I need to bring up AR0544 on Android with imx8mp ISP support. Could you help?

Currently I have integrated driver, dtb, ISI lib, and after running camera app of Gallery, I met below error:

09-20 21:51:36.543 546 729 W CameraService: getConcurrentCameraIds: camera id 0 does not exist
09-20 21:51:36.545 1617 1617 W CAM_Camera2OneCamMgr: No back-facing camera found.

Hi @bingyan ,

As we discussed offline, to bring up new camera with 8MP ISP on Android OS, you can refer to the section 8 under i.MX Android Frequently Asked Questions - NXP Community.

Generally speaking that, you need to make sure the new sensor dtb/ko/so/cfg/xml/json to be configured correcly. You also need to make sure that the camera_name in camera_config_***.json file to be set correctly. For camera connected to csi0 and isp0, it should be viv_v4l20. And viv_v4l21 for camera connected to csi1 and isp1.

It's glad that you finally make ar0544 work now.

Regards,

Zoey

I added json under  device/nxp/imx8m/evk_8mp/camera_config_imx8mp-ar0544.json

and after building I can get out/target/product/evk_8mp/vendor/etc/configs/camera_config_imx8mp-ar0544.json

but on board under path /vendor/etc/configs I can't see file camera_config_imx8mp-ar0544.json
