20250118拿掉荣品pro-rk3566开发板上Android13下在uboot和kernel启动阶段的Rockchip这个LOGO标识
2025/1/18 15:12
缘起：做飞凌OK3588-C开发板/核心板【Linux R4】的时候，测试/生产要求没有开机LOGO【飞凌/Rockchip】
要求：黑屏或者中性界面。
这次决定也这样干。结果Vysor可以进Android的UI界面，LCD屏进不了。
于是将Rockchip给的BMP文件在WIN10自带的画图中给直接涂黑了！
【可能的原因：荣品不让拿掉LOGO文件 或者是 Android13系统要求的】使用ACD See 5.0很容易知道logo.bmp和logo_kernel.bmp都是256色的BMP文件。【654x270x256色】
如果使用WIN10自带的画图工具编辑之后保存成为24bit的BMP文件也是可以正常使用的。

我们这边是建议修改中性的或者黑屏logo
板子首先跑 uboot 接着跑kernel 再跑到系统，最后加载对应的应用，这个开机log 是在板子跑进系统前展示的画面，去不去掉并不影响开机时间，建议不要改显示的部分.直接去掉反而会对稳定性有影响
