Sorry for bumping an old thread but I would like to provide an update that might be relevant.
Since the last post I've transitioned to custom designed FPC with length matching and impedance made correctly. With the same software stack, csi0 showed no progress (still getting those ecc errors), the csi1 worked perfectly.
I have also tried the recent fix to rk35xx_veye_bsp (13684db), and to my surprise, the situation is now different. The camera on csi0 now shows 60 fps picture, but with colors distorted (heavy red, green, blue splashes over the objects) and the dmesg shows the following:

When connected to csi1, the picture is as good as always.
I hope that my update will help you with your debugging effort. Feel free to ask me to do some additional testing.
