最近在开发RK3128 , 客户反馈开机到显示logo 时间过长,于是将对应DTS 的uboot logo 打开
方法如下,将uboot-logo-on 置成1
&fb {
rockchip,disp-mode = ;
rockchip,disp-policy = ;
rockchip,uboot-logo-on = <1>;
};
打开后发现recovery mode 或是OTA 升级,黑屏,无法显示升级进度。
抓kernel log 发现如下地方比较可疑。

原来RK 方案有uboot logo 和kernel logo
分别在RK_3128kernellogo.bmp 和RK_3128kernellogo_kernel.bmp 下。
因为之前只改了uboot logo。 Kernel logo 还是RK 原生的
于是将两个分辨率改成一样的
编译烧录后验证OK 。
