      今天刚收到D1 开发板哪吒专用8寸MIPI 屏幕,好不容易简单点亮了,发现屏幕有个异常的方块,应该是质量问题?

      屏幕右边放大看清楚些。

        请输入命令行进行测试:

        cd /sys/kernel/debug/dispdbg
        echo disp0 > name; echo switch1 > command; echo 1 4 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;
        

        如果仍然出现异常线条,请淘宝发起退换货
        参考文档:https://d1.docs.aw-ol.com/study/study_5connect/#_4
