R128-S2 驱动 1024x600 RGB 显示屏 并运行 LVGL发布在 A Series
由于屏幕较大首先精简系统内存，关闭DSP核心，并将 RV 核心移到 HSPSRAM 上提高带宽。配置 LV_COLOR_DEPTH 16 提高帧率降低内存占用
patch 如下，增加了新方案r128-devkit-rgb：161ca91b-f759-4108-8bfc-85114394da0c-r128-devkit-rgb.tar.gz
编译打包即可
700ms启动 LVGL：

回复: 开机后显示驱动加载流程疑问？发布在 T Series
@tivon uboot下的显示驱动会被调用初始化屏幕显示logo，内核驱动里获取到屏幕已经被初始化，则显示驱动不会被调用，以免出现再次初始化屏幕导致闪屏的问题，达到平滑显示logo
