器件型号：TDA4VM 您好、TI 专家：
我们使用连接到 TDA4 (CSI1)的 MAX9286解串器来捕获四个摄像头。 我们已经配置了 MAX9286并获得了正确的寄存器 STAUTS (Framesync 锁定、Vsync 锁定)、输出 CSI 数据类型为 YUV422-8Bit。 但是、当在 VISION_APPS 中运行 single_cam 或 multi_cam 示例时、我们得到了错误的图像。 (版本7.2 SDK、传感器为960P 25fps)
根据 e2e 上的其他线程、我们编辑代码：
/* Config initialization */
tivx_capture_params_init(&local_capture_config);
local_capture_config.numInst = 1U;
local_capture_config.numCh = 1U;
local_capture_config.instId[CAPT_INST_ID] = 1;//CAPT_INST_ID;
local_capture_config.instCfg[CAPT_INST_ID].enableCsiv2p0Support = (uint32_t)vx_true_e;
local_capture_config.instCfg[CAPT_INST_ID].numDataLanes =
sensorParams.sensorInfo.numDataLanes;
local_capture_config.chInstMap[CAPT_INST_ID] = 1U;
local_capture_config.instCfg[CAPT_INST_ID].laneBandSpeed = TIVX_CAPTURE_LANE_BAND_SPEED_560_TO_640_MBPS;
我们只有在运行 single_cam 时才会进行警告、并且帧正在计数、但帧速率错误。 (应为25fps，但小于25fps)
[MCU2_0] 3637.109145 s: VX_ZONE_WARNING:[tivxCaptureSetTimeout:759] CAPTURE: WARNING: Error frame not provided using tivxCaptureRegisterErrorFrame, defaulting to waiting forever !!!
我们还读取了 Phy 寄存器：

看起来在 Phy 中是正确的。
我们错过了什么吗？ 谢谢你
