 此 BSP 默认只开启了 GPIO 和 串口0 的功能，如果需使用 SD 卡、Flash 等更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
 
 1. 在 bsp 下打开 env 工具。
-
 2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
-
 3. 输入`pkgs --update`命令更新软件包。
-
 4. 输入`scons` 命令重新编译工程。
 
+更多细节请参见使用指南：https://ab32vg1-example.readthedocs.io/zh/latest/introduction.html
+
 ## 注意事项
 
 波特率默认为 1.5M，需要使用 [Downloader](https://github.com/BLUETRUM/Downloader) 下载 `.dcf` 到芯片，需要编译后自动下载，需要在 `Downloader` 中的下载的下拉窗中选择 `自动`；目前暂时屏蔽 uart1 打印

+# NK-RTU980
+## 1. Introduction
+NuMaker-RTU-NUC980, also known as Chili, is a Nuvoton’s development platform that uses NUC980DR61YC microprocessor with a 64-pin package on a 50 mm x 50 mm dimension PCB. Chili board provides a high-end hardware features including a NUC980DR61YC ARM926EJ-S processor with 64 MB DRAM, 32MB SPI NOR Flash, 10/100 Ethernet MAC interface, USB 2.0 High Speed host/device connector, CAN bus, RS-485 and five GPIOs. Crypto engine supports RSA2048, AES256, ECC, SHA512 algorithm and a Pseudo Random Number Generator for communication security protection.
