求助,OK1131i-s开发板如何适配mipi 屏幕?
本帖最后由 蒙工 于 2026-1-13 16:35 编辑我按https://forlinx-book.yuque.com/pxh4d1/gfqde1/ia3hh7ecgabw8sph 说明把display_menu.c 改了:

设备树也都改了,在./build.sh config 选的4.mipi_1024_600板子,编译烧录进去没有反应,我示波器看,MIPI CLK也没有输出,不知道怎么适配mipi屏幕,求助各位大神,谢谢,感激不尽
这个板子有没有点过MIPI朋友求助了，困扰了好多天 已解决,问题是硬件板子Pin错位了,还有厂家给的初始化代码有问题,吧初始化代码去掉能正常显示了 蒙工 发表于 2026-1-16 13:48

老哥是直接去掉还是自己修改那，能不能贴个图看看
