TDA2X运行 Multi-Camera LVDS Use-cases demo Fvid2_create()函数创建失败



您好,我们参考TDA2X EVM板设计了我们自己的硬件板子(主要改动是去掉CPLD,只保留四路FPD LINK CAMERA直接接入tda2x vin) 。然后修改   5CH LVDS VIP Capture+Surround View+Edge Detect+HDMI DIsplay  DEMO,在我们自己的板子上运行时,发现VidSensor_create()函数中到下面这一步:

createParams->sensorHandle[chanNum] = Fvid2_create(sensorDrvId,sensorInstId,&sensorCreateParams,&sensorCreateStatus,NULL);  Fvid2_create返回值为NULL,创建失败。请问是会是哪方面原因造成的?(修改后的DEMO在EVM板上运行时,Fvid2_create 可正确返回)   谢谢
