CSI0 with 16-Bit video does not receive any frame

We have some issues with our Board trying to receive a 16-Bit video Stream (YUYV with external HSync and VSync) with 1080p25 resolution from an external SOC connected to CSI0 of IPU1 of our iMX6DL
(Pixel Clock ~ 78MHz, HSync Freq ~28kHz, VSync Freq 25Hz).
See schematics attached.
We have TVP5150 connected on CSI1 and also set the GPR13 register to 0x24 so that the routing of both CSI interfaces into the IPU is ok.
TVP5150 input is working very well but on CSI0 we have some severe issues that the IPU does not forward any frame into the V4L interface.
If we misconfigure CSI0 to be a BT656 device with integrated sync then we get some green frames forwarded now and then into our gstreamer pipeline.
The driver for our CSI0 Capture device is hdtv.c which is taken over from our working tvp5150 driver (also attached).
We have extended mxc_v4l2_capture.c so that if we configure V4L2_IF_TYPE_BT656_MODE_NOBT_16BIT that csi_param.data_width = IPU_CSI_DATA_WIDTH_16 is set.
We are running the original 4.1.15 kernel released by NXP.
we also tried with 8-Bit width but it does not work either.
We already checked all electrical connections (by configuring the pins as GPIO and checking for input level and also using an oscilloscope) - all this looks alright (Vsync, HSync are positive pulses, PixelClock samples on rising edge).
The CSI0 registers in IPU look ok as well.
Attached is the console log and also our DTB file.

Hello Sebastian，

For the video input application of i.MX6Q/D/DL/S, it is very mature. There are many answers from i.mx experts in our community. According to your situation, you can refer to these two links first.

1. 16bit BT1120 does not work on MX6Q 

The link is about software.

2. connections

https://community.nxp.com/thread/314211 

Hope above information is helpful for you.

Have a nice day!
B.R,

Weidong

Dear Weidong,

The issue is that we do not use BT1120 but a format with external hsync and vsync that is why I think those threads are not applicable but somehow the imx6 CSI does not react on the hsync vsync signals.

Hello Sebastian,

OK, got it.

Your application is the same as that of the link:

https://community.nxp.com/docs/DOC-97981 

RGB565 data should be captured with generic 16 mode.

refer to the docment, please!

Have  a nice day!

B.R,

weidong
