A201型RV1126开发板+GC2053+GC2093，编译SDK烧录固件后vlc拉不到流

按照EB-RV1126-DC-201型开发板快速入门手册V2.3_E.pdf修改dts编译SDK烧录后，ifconfig eth0没看到IP地址：

手动输入ifconfig eth0 192.168.100.75后用VLC拉视频流rtsp://192.168.100.75/live0 没有反应。

执行/oem/usr/bin/rkmedia_vi_venc_rtsp_test -a/oem/etc/iqfile
s/直接coredump。于是按照手册先执行/oem/RkLunch-stop.sh，结果如下：

再次执行/oem/usr/bin/rkmedia_vi_venc_rtsp_test -a/oem/etc/iqfile
s/可以看到源源不断的packet了，但是再次用VLC拉流还是没有反应，拉流时显示：

登录http://192.168.100.75/ 也看不到视频流。查看dmesg发现有Detected GC2053 sensor。
