# Allwinner tina板级支持包
|
||
|
||
## 1. 简介
|
||
|
||
Allwinner tina 是由全志公司推出的ARM9内核的SOC
|
||
包括如下硬件特性：
|
||
|
||
| 硬件 | 描述 |
|
||
| -- | -- |
|
||
|芯片型号| tina系列 |
|
||
|CPU| ARM9 |
|
||
|主频| 408MHz |
|
||
|片内DDR | 32MB |
|
||
|板载SPI Nor Flash | 8/16MB|
|
||
|
||
## 2. 编译说明
|
||
|
||
| 环境 | 说明 |
|
||
| --- | --- |
|
||
|PC操作系统|Linux/MacOS|
|
||
|编译器|arm-none-eabi-gcc version 6.3.1 20170620 (release)|
|
||
|构建工具|scons|
|
||
### 2.1 下载源码
|
||
|
||
```
|
||
git clone https://github.com/RT-Thread/rt-thread.git
|
||
```
|
||
### 2.2 配置工程并准备env
|
||
先下载安装 RT-Thread 的env工具([env工具下载链接][1]),再执行下面命令设置 RT-Thread 操作系统的开发环境
|
||
```
|
||
cd rt-thread/bsp/allwinner_tina
|
||
scons --menuconfig
|
||
source ~/.env/env.sh
|
||
pkgs --upgrade
|
||
|
||
```
|
||
### 2.3 编译安装下载工具
|
||
```
|
||
pushd /tmp
|
||
git clone https://github.com/Icenowy/sunxi-tools.git
|
||
pushd sunxi-tools
|
||
git checkout -b f1c100s origin/f1c100s
|
||
make
|
||
sudo make install
|
||
popd
|
||
popd
|
||
```
|
||
### 2.4 编译
|
||
```
|
||
scons
|
||
```
|
||
如果编译正确无误，会产生rtthread.elf、rtthread.bin文件。其中rtthread.bin需要烧写到设备中进行运行。
|
||
|
||
## 3. 烧写及执行
|
||
**烧写工具目前仅支持Linux/MacOS环境,请在Linux/MaxOS环境下进行烧写操作**
|
||
当正确编译产生出rtthread.bin映像文件后可以使用下面的方式来烧写到设备中。
|
||
|
||
### 3.1 编译初始化引导文件
|
||
编译依赖 arm-eabi-gcc
|
||
```
|
||
pushd ../../..
|
||
git clone https://github.com/lymzzyh/tina-spl.git
|
||
pushd tina-spl
|
||
make
|
||
cp output/f1c100s.bin ../rt-thread/bsp/tina/tina-spl.bin
|
||
popd
|
||
popd
|
||
```
|
||
### 3.2 下载并运行
|
||
|
||
|
||
1. 短接flash 1、4脚(当flash中无可引导代码时无需此步骤)
|
||
2. 连接USB
|
||
3. 松开短接的引脚
|
||
4. 输入下列指令
|
||
|
||
|
||
```
|
||
sudo sunxi-fel -p write 0x00000000 tina-spl.bin
|
||
sudo sunxi-fel exec 0x00000000
|
||
sudo sunxi-fel -p write 0x80000000 rtthread.bin
|
||
sudo sunxi-fel exec 0x80000000
|
||
```
|
||
|
||
### 3.3 运行结果
|
||
|
||
如果编译 & 烧写无误，会在串口0上看到RT-Thread的启动logo信息：
