回复: V853 DDR原理图问题发布在 V Series
AW平台的DRAM控制器支持地址线REMAP，可以通过REMAP简化外部不同种类的DRAM的连接。
这个REAMP是固定在芯片里的不能自己修改，在电路原理图可以看到REMAP的引脚。
如图，如果需要挂DDR3内存，需要接DDR3的REAMP，如果需要接DDR2，可以接默认的REMAP
举个其他平台的例子：
这里接的是 LPDDR4，使用LPDDR4的REMAP
这里接的是DDR4，使用DDR4的REMAP

回复: v853 vin通路配置发布在 V Series
（1）在线模式：四个vipp和dma实体，最大缩小比例为16*16，每路最多可支持16个orl
（2）离线模式：每个vipp和dma可分时复用为4个vipp和dma虚拟体，四个vipp和dma实体相互独立，在线模式和离线模式开关也是相互独立的；
（3）VIPP和DAM的分时复用（离线模式）与isp和tdm的分时复用（离线模式）是绑定关系，即tdm和isp开启了离线模式，vipp和dma的输入端如果是isp，那么vipp和dma也需要开启离线模式；
（4）只有VIPP0和dma0实体支持VE在线编码，而vipp0在线，如果vipp00的输入端为isp，那么tdm和isp也只能配置在线模式，而isp在线，那么四个vipp和dma实体都只能配置在线模式；online 和 offline 配 置 方 式 在 board.dts ， 所 以 需 要 在 对 应 版 型 的 board.dts 中 找 到 vind0 节 点 配 置 列 表 ， 对 应 关 系 为 tdm 对 应 节 点 ， isp 对 应 isp00 节 点 ， vipp 对 应 scaler00 、 scaler10 、 scaler20 和 scaler30 节 点 ， dma 对 ， 应 vinc00 、 vinc10 、 vinc20 和 vinc30 节 点 。
- 在线模式，单路3输出
- 离线模式，2路8输出

IMX219 同样可以使用，但是请注意4lane的摄像头不可适配2lane的数据

Sensor输出图像格式
sensor输出图像格式定义在sensor_format_struct结构体中，vin v4l2驱动框架通过获取sensor_format_struct结构体成员信息来获取当前sensor输出图像格式，sensor_formats结构体中需要填写的成员是.desc和.mbus_code。
.desc是描述sensor输出的图像格式，本例中gc2053是RGB Raw sensor，故.desc成员填写为"Raw RGB Bayer"。.mbus_code为sensor图像数据输出顺序，sensor RAW图像是以Bayer格式传输的（每个像素只表示RGB其中一个分量），常见的Bayer格式为：RGGB、BGGR、GRBG、GBRG，这个可以询问一下sensor原厂或者翻阅sensor datasheet进行查找。.mbus_code若填错, 会导致色彩偏紫红和出现网格状纹理。 本例中
gc2053图像输出格式为RGGB，且当前的配置是10bit mipi接口，故.mbus_code填写为
MEDIA_BUS_FMT_SRGGB10_1X10，若当前调试的sensor配置是8bit输出，
则.mbus_code填写为MEDIA_BUS_FMT_SRGGB8_1X8，按照这种规则进行填写。static struct sensor_format_struct sensor_formats[] = { { .desc = "Raw RGB Bayer", /* 填写 Sensor 初始化时默认的 Bayer 格式，目的是告知主控端ISP当前图像的 Bayer 格式，ISP需要以同样的格式来接收和处理图像数据 */ .mbus_code = MEDIA_BUS_FMT_SRGGB10_1X10, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 1 }, }; 如果
sensor输出图像格式是YUV的话，则需要根据sensor图像数据输出顺序选择YUYV/VYUY/UYVY/YVYU其中一种，如下：static struct sensor_format_struct sensor_formats[] = { { .desc = "YUYV 4:2:2", .mbus_code = MEDIA_BUS_FMT_YUYV8_2X8, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 2, }, }; 同时，
sensor_get_fmt_mbus_core函数也要将当前sensor的图像输出格式赋值给函数参数*code，有些sensor在翻转后RGB顺序不会自动进行调整，需要主控端ISP需要按照当前sensor翻转后的图像格式更新RGB顺序，避免翻转后出现图像色彩异常的问题，如下，gc2053支持翻转后sensor内部自动调整RGB顺序，所以函数参数*code仍赋值为MEDIA_BUS_FMT_SRGGB10_1X10。static int sensor_get_fmt_mbus_core(struct v4l2_subdev *sd, int *code) { *code = MEDIA_BUS_FMT_SRGGB10_1X10; // gc2053 support change the rgb format by itself } static long sensor_ioctl(struct v4l2_subdev *sd, unsigned int cmd, void *arg) { int ret = 0; struct sensor_info *info = to_state(sd); switch (cmd) { case VIDIOC_VIN_GET_SENSOR_CODE: /* vin v4l2框架层在sensor翻转接口被调用后， 通过VIDIOC_VIN_GET_SENSOR_CODE获取当前sensor的RGB顺序 */ sensor_get_fmt_mbus_core(sd, (int *)arg); break; default: return -EINVAL; } return ret; } -
