Hi:

We use adv7482 on our custom board. I meet a problem that MIPI RX can't receive 480i from adv7482 correcly.

I have done the following.

cvbs in(576i) -->SDP(free run) -->csi txa 1 lane -->MIPI RX      MIPI RX can receive data correctly. Image looks fine.
cvbs in(576i) -->SDP -->csi txa 1 lane -->MIPI RX                      MIPI RX can receive data correctly. Image looks fine.
CP(free run 480i) -->csi txa 1 lane -->MIPI RX                            MIPI RX can receive data correctly. Image looks fine.

 

cvbs in(480i) -->SDP(free run) -->csi txa 1/2 lane -->MIPI RX            MIPI RX can't receiver data correctly.

 

we configure the adv7482 according to CVBS Input MIPI TxA 1-Lane Output

 

I would appreciate any help.
thanks!
