IMX6 CSI Capture does not work

swendt — Tue, 12 May 2020 08:04:51 GMT

I have a HW with TC358743 HDMI Decoder connected to MIPI-CSI interface and a TVP5150AM connected as 8-Bit parallel device to CSI1. I am running NXP kernel 4.1.15.

I2C setup etc. all works well, also registration in V4L2 etc but if try to capture the stream of either device, the camera_callback function is never called and no buffers are queued, e.g. using gstreamer or v4l2grab.

I can see that there is activity both on MIPI-CSI and on CSI1 as soon as I start streaming but camera_callback s never called.

Please find my device tree file and my kernel config attached.

Is there any way to further debug the IPU why there is no callback executed ?

Re: IMX6 CSI Capture does not work

swendt — Tue, 12 May 2020 16:34:52 GMT

I have found the issue for HDMI In - I need to set regmap_update_bits(gpr, IOMUXC_GPR13, 0x3F, 0x20); so HDMI works well then.

But the TVP5151 in on CSI1 still does not work.

Hi Sebastian

for TVP5151 one can look at

imx6/0061-ARM-i.MX6-tvp5150-add-tvp5150-video-decoder-support.patch at master · compulab-yokneam/imx6 · GitHub

Also instead "imxv4l2videosrc" community gstreamer-imx plugin one can try

nxp imx-gst1.0-plugins described in Linux Guide found in linux documentation on

i.MX Software and Development Tools | NXP

Thanks, Igor.

Hi, actually I am using exactly this driver but as mentioned the camera_callback is never called.

Regards,

Sebastian

Hi Sebastian

one can test with mxc_v4l2_tvin.c from unit tests
