# AARCH64 工作模式使用
|
||
|
||
- 当开发者需要基于 Phytium 系列芯片进行开发时，可以从以下几个步骤出发配置芯片
|
||
|
||
## 1. 如何选择芯片
|
||
|
||
```shell
|
||
scons --menuconfig
|
||
```
|
||
|
||
开发者通过以下选择进行配置
|
||
|
||
```
|
||
Standalone Setting > Board Configuration > Chip
|
||
```
|
||
|
||
|
||
|
||
|
||
## 2. 如何选择驱动
|
||
|
||
|
||
```shell
|
||
scons --menuconfig
|
||
```
|
||
|
||
开发者通过以下选项进行驱动的使能
|
||
|
||
```
|
||
Hardware Drivers Config > On-chip Peripheral Drivers
|
||
```
|
||
|
||
|
||
|
||
|
||
## 3. 开启SDK中内部调试信息
|
||
|
||
|
||
```shell
|
||
scons --menuconfig
|
||
```
|
||
|
||
开发者通过以下选项进行调试信息等级的设置
|
||
|
||
|
||
|
||
|
||
|
||
## 4. 编译程序
|
||
|
||
```shell
|
||
scons -c
|
||
scons
|
||
```
|
||
|
||
- 完成编译之后目录下将会生成以下几个文件
|
||
|
||
```
|
||
rtthread_a64.bin
|
||
rtthread_a64.elf
|
||
rtthread_a64.map
|
||
```
|
||
|
||
## 5. 打包导出工程源代码
|
||
|
||
|
||
- 指定工程名和路径，打包RT-Thread内核和Phytium BSP代码，可以导出一个工程工程
|
||
```
|
||
python ./export_project.py -n=phytium-a64 -o=D:/proj/rt-thread-e2000/phytium-a64
|
||
```
|
||
|
||
|
||
|
||
|
||
- 进入打包工程的目录，修改工程根目录 Kconfig 中的路径 BSP_DIR 和 STANDALONE_DIR
|
||
> env 环境中的 menuconfig 不会调用 SConstruct 修改路径环境变量，因此需要手动修改路径
|
||
|
||
```
|
||
config BSP_DIR
|
||
string
|
||
option env="BSP_ROOT"
|
||
default "."
|
||
|
||
config STANDALONE_DIR
|
||
string
|
||
option env="STANDALONE_DIR"
|
||
default "libraries/standalone"
|
||
```
|
||
|
||
- 输入 menuconfig 和 scons 完成编译
|
||
|
||
|
||
## 6. 将工程导入 RT-Studio
|
||
|
||
- 在 RT-Studio 使用功能`RT-Thread Bsp 到工作空间`，导入 5. 中导出的 BSP 工程
|
||
- 设置 BSP 工程的交叉编译链后进行后续开发
|
