# 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|
1) 下载源码
```
git clone https://github.com/RT-Thread/rt-thread.git
```
2) 配置工程并准备env
```
cd rt-thread/bsp/allwinner_tina
scons --menuconfig
source ~/.env/env.sh
pkgs --upgrade
```
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
git checkout -b f1c100s origin/f1c100s
make
sudo make install
popd
popd
```
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。
1)编译初始化引导文件
编译依赖 arm-eabi-gcc
```
pushd ../../..
git clone https://github.com/uestczyh222/tina-spl.git
pushd tina-spl
make
cp output/f1c100s.bin ../rt-thread/bsp/tina/tina-spl.bin
popd
popd
```
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
```
### 3.1 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：
```
\ | /
- RT - Thread Operating System

```
## 4. 驱动支持情况及计划
| 驱动 | 支持情况 | 备注 |
| ------ | :----: | :------: |
| UART | 支持 | UART0/1/2 |
| GPIO | 支持 | / |
| clock | 支持 | / |
| mmu | 支持 | / |
### 4.1 IO在板级支持包中的映射情况
| IO号 | 板级包中的定义 |
| -- | -- |
| PE8 | USART2 RX |
| PE7 | USART2 TX |
| PA3 | USART1 RX |
| PA2 | USART1 TX |
| PE1 | USART0 TX |
| PE0 | USART0 RX |
