We have unit made of two boards. One board with IMX6Q processor and another with DM8148 processor.
Board with DM8148 processor is sending video on 8-bit lines with BT.656 (embedded sync) configuration.
In this case we don't need any decoder chip or camera sensor we are getting digital data directly from DM8148.
This is data is as per BT.656 format and NTSC (720 x 480). To capture this data I have hard coded BT.656 , NTSC and () resolution in "mxc_v4l2_capture.c" file.
We checked in scope that clock is coming properly (27 Mhz) and data is also coming.
Still when we try to capture data using v4l2 application we are getting below error.
ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0
Below are the pins we are using and configuration in dtsi file.
Any suggestions will appreciated for this issue?
Do we need any additional configuration? Any thing needed from our side.
