HI everyone


I already have a board which contains a IMX6q and connect to a sensor with physical 4 mipi data lanes.

now I can receive the image frame by 2 lanes setting(with 1Ghz mipi clk).

but when I change the sensor setting to 4 lanes(with 1Ghz mipi clk),

and modify the device tree to 4 lanes, I can't get the image frame.

Could anyone provide any suggestions about 2 lanes to 4 lanes?

which code or settings should I modify?

thank you all for reading this issue.


&mipi_csi {
status = "okay";
ipu_id = <0>;
csi_id = <1>;
v_channel = <0>;
lanes = <4>;//modify here
