全志平台双路LVDS配置

在全志A40I调试双路lvds 起初看参数配置去调试,但是一直是黑屏,所以到处在网上产找资料
最终双路lvds终于有显示了,话不多说,直接进入正题
先查看双路lvds的规格书
lcd_dclk_freq, lcd_ht 是指两个 link 合并后的时钟频率和 cycle 个数。 故
lcd_dclk_freq = 54x2 = 108, lcd_ht = 844x2=1688
a40i-android7.1\lichee\tools\pack\chips\sun8iw11p1\configs\a40-boardcon\sys_config.fex
我参考了全志A20_LCD模块开发说明文档
里面有个错误lcd_vt也x2,所以我参考使用这个方法。lvds一直没显示。最后在百度文库发现这个问题!
