dptx的phy的线序与标准的dp接口不同，是否可以使用remap功能将其对应映射。映射关系如下所示。DPTX phy线序与dp标准接口连接有问题，是否可以通过remap功能将lane序调整正确。

您好

对于通道重映射、您能否确保写入 APB 寄存器0x30 (APB_LANE_REMAP)= 0x14E？

remap后使用1个lane进行link training不成功，4条lane可以成功，也可以显示图像。

您好

不知道您的意思。您说1个信道不成功、但4个信道可能成功、您能否说明哪个信道的链路训练不成功、以及发生这种情况的频率？您是否可以运行此脚本来读取983的 DP 训练状态和 MSA 值？
