MIPI CSI信号接收问题

DisplayPort to MIPI-CSI Converter 芯片输出的MIPI信号,输入给MIMX8ML8CVNKZAB(imx8mplus)的MIPI CSI-2 Port2。已确认硬件连接无问题,DisplayPort to MIPI-CSI Converter 芯片输出MIPI CLOCK 单端信号实测频率297MHz,imx8mplus目前仅在dts中设定了HS_SETTLE为13。我们有2块相同的电路板、写入一样的程序,出现以下状况:

1、电路板A:DisplayPort to MIPI-CSI Converter 芯片、imx8mplus都为continuous clock mode或者都为Non-continuous clock mode,imx8mplus视频流获取异常。

2、电路板B:DisplayPort to MIPI-CSI Converter 芯片、imx8mplus都为continuous clock mode,imx8mplus视频流获取正常。DisplayPort to MIPI-CSI Converter 芯片、imx8mplus都为Non-continuous clock mode,imx8mplus视频流获取异常。

寄存器、LOG参见附件excel “dp-Register-文字注释”。拜托帮忙判断下,寄存器、LOG是否有错误信息反馈出来?imx8mplus视频流获取异常原因,该如何解决?
