LPC408x BSP 使用说明
简介
LPC408x 是 RT-Thread 推出的一款基于 LPC408x 系列的评估板，板载资源主要如下：
| 硬件 | 描述 |
|---|---|
| 芯片型号 | LPC4088FET208 |
| CPU | ARM Cortex M4 |
| 主频 | 120M |
| 片内 SRAM | 64K |
| 片外 SDRAM | 32M |
| 片内 FLASH | 512K |
编译说明
LPC408x 板级包支持 MDK4﹑MDK5 开发环境和 GCC 编译器，以下是具体版本信息：
| IDE / 编译器 | 已测试版本 |
|---|---|
| MDK4 | MDK4.74 |
| MDK5 | MDK524a |
| GCC | GCC 5.4.1 20160919 (release) |
请注意！！！
在执行编译工作前请先打开ENV执行以下指令（该指令用于拉取必要的库，否则无法通过编译）：
pkgs --update
烧写及执行
供电方式：使用方口 USB 连接电脑和开发板。
下载程序：使用 JLink/ULink 等等仿真器连接到板子上的 20Pin 仿真口。
串口连接：板载 CP2102，连接了 USB 后打开相应的串口即可。
运行结果
如果编译 & 烧写无误，当复位设备后，会在串口上看到 RT-Thread 的启动 logo 信息：
