请问：我使用的是8寸群创的LCD屏，移植驱动的时候，上面这些参数怎么改？

参考800×600 VGA选项

哪里有800*600 ，VGA选项？

飞凌-alexlee · 发表于 2011-3-14 12:58:14

在booltoader。有个屏幕分辨率设置，你看一下手册～

改成这样，不知道哪儿不对

.left_margin       = 55,
      .right_margin       = 63,
      .hsync_len       = 119,
      .upper_margin       = 36,
      .lower_margin       = 22,
      .vsync_len       = 5,

这几位看看～

这几位是根据bootloader上面的800*600选项下面的参数写的
