大神们，帮我看看这个问题！ ==== Your input Sensor type is ov9712 ==== init register config failed ffffffff! [SAMPLE_COMM_VI_BindVpss]-1143: failed with 0xffffffff! [SAMPLE_VENC_720P_CLASSIC]-186: Vi bind Vpss failed! [SAMPLE_COMM_VI_UnBindVpss]-1455: failed with 0xffffffff! init register config failed ffffffff! init register config failed ffffffff! Get ISP Interrupt Failed with ec 0x1! program exit abnormally! rtusb init rt2870 ---> 这个是我执行 ./sample_venc 0 后打印的异常退出的错误信息，我的load3518e 中已经执行成功了，里面对应的sensor我也改为了我的相应的ov9712，sample目录下的makefile.param中也改为相应的ov9712了，但是不知道为什么还出现这个问题，求大神帮忙看看！谢谢！
