SN65DSI86-Q1: DP link trainig失败

Hi，ti 我当前使用sn65dsi86将DSI转换为DP，但是DP link training 一直是失败。
这是我的初始化序列，可以帮忙看一下这个问题吗？

i2cset 0x5c 0x40 
i2cset 0xFF 0x07
i2cset 0x16 0x01 
i2cset 0xFF 0x00
i2cset 0x5a 0x05
i2cset 0x10 0x26
/*detect link training*/
i2cset 0x94 0x80
i2cset 0x95 0x01
i2cset 0x0d 0x01
i2cset 0x96 0x0a
/*wait for link training*/
i2cget 0x96 

这是寄存器的dump:

您好，关于您的问题。

第一，首先要保证上电时序满足datasheet P15的上电时序。

第二，附件是计算初始化寄存器配置SN65DSI86 Register Calculator的工具。
