DS90UB964-Q1: Line-Concatenated Forwarding fail.

Part Number: DS90UB964-Q1

Helllo,

we need to use Line-Concatenated Forwarding function. two 1280*720 cameras(913a) + DS90UB964-Q1.

RIN0 ON (RIN1 RIN2 RIN3 OFF), MCU's  preview size 1280*720.then it works.


RIN3 ON (RIN0 RIN1 RIN2 OFF), MCU's  preview size 1280*720.then it also works.


RIN0 RIN3 ON (RIN1 RIN2 OFF), MCU's  preview size 2560*720,then it does't work.

there is no preview on the screen.

register setting below

(0x01,0x02);
(0x32,0x01);
(0x33,0x01);
(0x4c,0x01);
(0x70,0x1E);
(0x4c,0x38);
(0x70,0x1E);
(0x6d,0x7f);
(0x21,0x3c);
(0x20,0x60);
(0x1f,0x03);
(0x58,0x58);
(0x7c,0xc0);
(0xbc,0x00);

Now I set reg 20 to 0x70,other regs don't change.

here is the preview,Rin3's preview is ok,Rin0 not ok

Now I set reg 20 to 0xe0,the preview like below. it does't show the good picture,but I can see the left part of the screen is changing when I move the Rin0 camera.

please help to fix this issue,thanks.
