 由于目前我们只在 rknext 中集成了该功能， 所以需要确认手中板子的 U-boot 是否是 2024 年 10 月份之后的版本，
 
+可在开机 log 中查看 U-boot 版本
+
 如：
 
 ```bash
 U-Boot SPL latest-2023.07.02-6-4257d241-g4257d241 (Oct 12 2023 - 07:58:46 +0000)
 ```
 
+:::tip
+
+该篇文章是以 "U-boot 已经是 2024 年 10 月份之后的 rknext" 为前提条件的
+
+:::
+
 ### 准备一张或者两张图片
 
+:::tip
+
+图片 width \* height 不能超过 200000
+
+:::
+
 ### 将图片转为 .bmp 格式
 
 1. 安装所需要的库

 Since we have only integrated this feature in rknext, you need to check if the U-boot on your board is from October 2024 onwards.
 
+U-boot version can be viewed in the boot log
+
 For example:
 
 ```bash
 U-Boot SPL latest-2023.07.02-6-4257d241-g4257d241 (Oct 12 2023 - 07:58:46 +0000)
 ```
 
+:::tip
+
+The article is predicated on the premise that “U-boot is already rknext after October 2024”
+
+:::
+
 ### Prepare one or two images
 
+:::tip
+
+Image width \* height must not exceed 200000
+
+:::
+
 ### Convert the image to .bmp format
 
 1. Install the required libraries
