Hi liang

if you are asking about ipu csi mapping no, it is fixed and described in

Table 62. Camera Input Signal Cross Reference, Format, and Bits Per Cycle

i.MX6DQ Datasheet

(1)thanks for your reply,i know my board only supports generic data csi0 input 16bit,but how to patch for kernel

,i want to know how to supports 16bit generic data csi0 input（CSI0_Data 4~CSI0_Data19）？

(2)besides,i find a surprising problem,my board suport 15pfs 1280X720/1024X768 30pfs/640X480 30pfs etc,

but not support 720P/1920X1080 15pfs video capture.error:ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0.
（when i use 8 bit dvp sensor interface）

Looking forward to your reply .thanks

hi igorpadykov,

thanks for your answer,

i want to know support generic data csi0 16bit input,I use fpga analog of camera support how to output  timing mode,

if it is without HSYNC non-gate-mode,isn't correctly?

(1) how to can output 16bit raw format?

(2)generic data csi0 16bit input,i can use  camera input yuyv (default format)?,isn't support?

[igorpadykov]

there is no support for csi generic data in nxp official software, so

you can just look at users experience on suggested threads.
