https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1523331/tda3xevm-camera-cpi-port

器件型号：TDA3XEVM

工具/软件：

我将使用 TDA3定制板。

传感器当前连接到 CPI 端口。

数据是 RAW14位。

我将其设置如下、但出现了错误。

SYSTEM_DF_RAW16；
SYSTEM_VIFW_16BIT
SYSTEM_VIFM_SCH_CPI

    尊敬的 Kim：

    但从下面的错误,它似乎你正在使用这个数据格式在显示屏中也... 请注意、显示屏不支持 RAW14数据格式、因此您需要将此格式转换为 YUV 或 RGB 等可视格式、然后才能在显示屏中使用。

    ispcore/vpscore_dss.c src @第1137行：

    此致、

    你(们)好

    更改 info->dataFormat = SYSTEM_DF_YUV422I_UYVY;后
    、错误消失。

    但是、当使用"p"进行检查时、不会检测到帧捕获。

    由于定制电路板上没有 HDMI、因此 HDMI INIT 部分被注释掉。
