Re: 新人求助,请问下zero的LCD驱动程序在哪里呢

主线(开源社区)和官方bsp 两个版本的驱动不同, 官方的功能比较全.

主线参考这个帖子: https://whycan.cn/t_561.html
官方bsp参考这个帖子: https://whycan.cn/t_682.html

查找驱动的方法:

怎么修改这个LCD驱动呢?我以一个1024*600的屏,按照晕哥个帖子修改,我把800*480的uboot的config拷贝了一份,然后修改启动参数,怎么修改都没反应,但是烧录这个licheepi0_v3s_bsp_linux_20101221_dump进去,能看到一点点图像,但不正常
