Ov5642 parrellel Camera Problem in the Boundary device

kishorepoojari · ‎05-15-2016

Hello All,

I am working on Boundary devices (nitrogen6x) , where we connected Ov5642 parallel camera to our board ,

camera is detected fine by the following command:

root@nitrogen6x:~# dmesg | grep ov5642

[ 7.916678] mxc_v4l2_master_attach: ipu0:/csi0 parallel attached ov5642:mxc_v4l2_cap0

[ 7.923284] ov5642 2-003d: created sysfs entry for reading regs

[ 7.927913] camera ov5642 is found

But when we try to open the Ov5642 camera application following error thrown

ERROR: unrecognized std! 0 (PAL=ff, NTSC=b000

ERROR: v4l2 capture: VIDIOC_QBUF: buffer already queued

ERROR: v4l2 capture: Capture stream has been turned on

ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

power_down_callback: ipu0/csi0

Please help me sort out this issue:

Regards,

Hi Kishore,

Please specify the following:

- Which OS is used (Android, Yocto, Buildroot, Ubuntu, Debian)?

- Which kernel version are you using? (3.0.35, 3.10.53, 3.14.28, 3.14.52)

- How do you start the camera? Are you using Gstreamer? If so, please provide your pipeline.

- Is the OV5642 sensor been bought from Boundary Devices too?

Regards,

Gary
