sn65dsi84 双路输出,lvds的评率是47MHZ,当芯片评率配置成6路分屏,频率为47的时候,显示异常,但测试彩条可以显示。设置成3路分屏 92MHZ,可以输出一个很模糊图像,配置和输入如下:
//divisor = 3 分屏3路,有显示

1. SN65DSI84适用于60fps WUXGA 1920 × 1200 分辨率(18bpp 和24bpp 彩色)和60fps 1366 ×768(18bpp 和24bpp),建议您确认下您的屏幕分辨率。
2. 建议您可以使用DSI Tuner软件配置您的寄存器,www.ti.com/…/dsi-tuner

屏参数在测试板子上OK,系统的参数设置也是正常的,现在是Android 到 sn65dsi84显示异常。没有数据输出。
