mx6s_csi_irq_handler Rx fifo overflow

Hi,

 

We (Yakov Shaulov and I) created custom board based on imx6slevk bsp and we connected parallel camera (gc0309 640x480 sensor) - created driver based on ov5640 located at subdev folder)

 

when we are trying to capture an image (using "gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! jpegenc ! filesink location=capture.jpeg") most of the time we get "mx6s_csi_irq_handler Rx fifo overflow" and the image we get is corrupt

Hi Nadav

before using gstreamer please try some basic camera unit tests in

imx-test-..test/pxp_v4l2_test
www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.7.tar.gz

if it works then try gstreamer using sect.7.3.3 Video encoding

attached Linux Guide.

Please use nxp gstreamer plugins (fsl-gst-plugin) and official bsp releases described on

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

 

Best regards
igor

Hi Igor

in section 7.3.3 (Video Encoding) it says that Video encoding requires VPU
we only need pictures captures and we don't have VPU (nor GPU on the board)

as I mentioned we are using "gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! jpegenc ! filesink location=capture.jpeg" or using "gst-launch-1.0 imxv4l2src device=/dev/video0 num-buffers=1 ! jpegenc ! filesink location=capture.jpeg"

the error ("mx6s_csi_irq_handler Rx fifo overflow") appears often

(we are using a custom board based on i.MX6SL with GalaxyCore gc0309 VGA CMOS Image Sensor [the sensor driver is placed in /drivers/media/platform/mxc/subdev] and we enabled CONFG_VIDEO_MXC_CSI_CAMERA, CONFIG_VIDEO_MXC_PXP_V4L2 & CONFIG_VIDEO_V4L2_SUBDEV_API)
