FPGA模拟SENSOR，MIPI CSI-2发送图像到RV1126-fpga sgmii

FPGA模拟SENSOR，MIPI CSI-2发送图像到RV1126

1：FPGA模拟Sensor， 使用MIPI CSI-2 Transmit，发送图像到RV1126。

2：MIPI CSI-2信号LANE，共5对。图像分辨率1920*1080，格式YUV422 8Bit，RGB565等。

3：调试

3.1：命令：v4l2-ctl -d /dev/video0 —set-fmt-video=width=1920,height=1080,pixelformat=UYVY —stream-mmap=3 —stream-skip=5 —stream-to=/tmp/cif2.out —stream-count=50 —stream-poll

3.2：log

4：图像读取：

adb pull /tmp/cif.out

5 结论

1：调试过程较为波折，最终实现该功能。

2：FPGA实现MIPI CSI-2发送，扩展了RV1126的视频输入接口。FPGA可实现LVDS，Cameralink，HDMI，SDI，自定义通信接口等向MIPI CSI的转换。

3：FPGA器件厂家，可选择安陆，高云，易灵思，紫光同创，LATTICE，XILINX等。

4：欢迎讨论交流。VX:moning_hello
