mipi通信失败的原因？如何解决？

5152 MIPI

问答对人有帮助，内容完整，我也想知道答案 0 更换了mipi屏幕，使用ili9881c驱动，设备树中修改内容如下： &mipi_dsi { status = "okay"; panel@0 { /compatible = "forlinx,mipi7";/ compatible = "ilitek,ili9881c"; reg = <0>; reset-gpios = <&gpio1 9 0>; dsi-lanes = <4>; vddio-mode = <2>; }; ... } 在drivers/gpu/drm/panel/中增加panel-ilitek-ili9881c.c，相应修改deconfg，Kconfig，Makefile。编译通过，烧到板中以后打印信息如下： [ 1.247836] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
