        @shz18877605430 看了晕哥的评论说改uboot下的.config,但是没有找到设置分辨率的地方。

          参考这个: 40PIN(AT043TN25) ==> 50PIN (AT070TN92) 转接板)

                  首先确认背光有没有亮,VGL/VGH/VCOM 电压对不对,

                  然后用示波器看下 DE/PCLK/HSYNC/VSYNC 这几个输出对不对.

                      @shz18877605430 晕哥,不是说要更改uboot得.config吗?但是我没找到改分辨率得地方,现在还是用480*272得分辨率,uboot往内核传参的地方没找到。
