TI中文支持网你好TI工程师，
我们正在使用DS90UB913A-Q1和DS90UB914A-Q1 & DS90UB954-Q1;
目前遇到一个棘手问题，希望尽快得到回复。谢谢！
我们的电路结构是 ：sensor 并行输出 —> DS90UB913 —-> DS90UB914 —-> FPGA LVDS转CSI2 —> 高通CPU SDM660, 这种情况是已经调好了；
这是954换914的电路结构：
sensor 并行输出 —> DS90UB913 —-> DS90UB954 —-> 高通CPU SDM660 CSI-2接口 我将913和sensor的驱动拿过来，sensor驱动没有动，913驱动也没有改动, 即913没有配置解串器的id, 所有外围和914配合使用时是一致的。 然后上电后发现954 CSI2是有输出的，但是输出分辨率有问题，查看寄存器后发现分辨率是2740×562，实际上,sensor配置输出是1948×1109;
同时查看913寄存器，发现Back channel的CRC报错，出现1处错误。
我们sensor使用的是1948×1109 raw 10配置。但是954识别到是是2740×562，913和954寄存器如下：

Jack Li：
不明白具体的问题，建议把问题详细描述一下，这样才能定位，再去检查内部的寄存器，看芯片是否工作正常。

这个结构，您出现图像是绿色的情况吗？
