hello everyone.!

   I am having a trouble in IPU.I programed a Non-Standard linux capture driver of IPU-CSI and capture data from FPGA.Timing is Gated-Mode timing.I don't care what the data is now but care the driver whether can work.I brief the below:

1、capture data size is 160*60 bytes.

2、FPGA occur the timing below:

3、I setting the IRQ  mode IPU_IRQ_CSI0_OUT_EOF.

4、the driver was insmod into the linux kernel.

5、I upload the driver code file to  accessory.

6、VSYNC signal indicate frame start,HSYNC signal indicate line start,both active low.signal occur whilw DLCK positive edge.

7、The IPU-CSI seems that does not working properly.

8、kernel was halt when i running  the driver test program, and occur a warning:

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00000001
