Uboot下增加启动LOGO图
1. 准备合适尺寸图片
在Tina-SDK uboot下，如果增加 logo图片，则需要准备一个 和屏幕分辨率大小类似 或者比他小的BMP图片。
我们已知 7寸RGB屏幕的分辨率是1024 x 600 ，那么就需要先找到一张 小于或等于 1024 x 600 的图（为了加快显示，尽量准备小于500k的图，图片会自动等比例居中显示）。
如下 我准备了 一张 分辨率 尺寸 为 782x276 分辨率的图，那么我需要先调整图片尺寸大小 ，再进行转换。
2. 转换图片格式
3. 拷贝到特定目录
~/tina-d1-h/device/config/chips/t113/configs/100ask/configs
4. 编译打包使用
ubuntu@ubuntu1804:~/tina-d1-h/device/config/chips/t113/configs/100ask/configs$ cd ~/tina-d1-h/
ubuntu@ubuntu1804:~/tina-d1-h$ ls

调整图像大小
7寸屏幕尺寸是1024x600那么我们可以做一个 2/1尺寸大小的图像，并且背景色改为 黑色，也就是需要做一个 512 x 300分辨率左右的黑色背景 logo 图。
类似下图所示，只有 312KB
之后，我们将原来的 bootlogo.bmp 替换，然后编译烧录进去，启动系统可以看到 新的图片 加载启动都很快。
