stuck in stop recording with ov5640

[xingruizhu]

hi supporter

our platform base on android-5.0.2, kernel 3.10.53 ,Freescale IMX6dl.

we porting camera ov5640 with the FSL oiginal driver and FSL original HAL.

With some modification about DTS info,  the preview/snapshot is normal.

But when we recording a few seconds and press the stop button, the preview is stuck at the same time.

the kernel log is :

Hi supporter

Is there update ?

[weidong_sun]

Hi Xingrui,

     My collegue and I used DEMO image to test functions(preview / record / stop during recording) of OV5640 camera according to your description, however, no any errors occured on SabreSDP board, didn't re-produce errors in the logs you sent to us.
In addition, If you have evaluation board, suggest you had better run demo image on it , then compare images with yours to find where the issue occured.

Regards,

Weidong
