已经用上信创电脑，操作系统是统信UOS（1070)，基于LINUX4.19.0版本，完全可以用来搭建开发环境。
一、资料收集
参考瑞昱官方文档：
https://aiot.realmcu.com/cn/latest/rst_rtos/rst_sdk/0_ameba_sdk_download/index.html
二、开发环境搭建
1、SDK下载
git clone https://github.com/Ameba-AIoT/ameba-rtos.git
或：
git clone https://gitee.com/ameba-aiot/ameba-rtos.git
2、安装Python
apt安装
sudo apt install python3 python3-pip python3-venv
由于统信UOS apt安装python只支持最高3.7版本，不满足要求。因此使用pyenv安装python
# 1.安装 pyenv
curl https://pyenv.run | bash
# 2. 重新配置 shell（根据你的 shell 选择）
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
source ~/.bashrc
# 3. 安装依赖和 Python 3.12.0
sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
pyenv install 3.12.0
pyenv global 3.12.0
3、软件合集包下载
主要包括Cmake，ninja等，如果系统中已经安装了这些，可以不用下载
mkdir /opt/rtk-toolchain
cd /opt/rtk-toolchain
wget https://github.com/Ameba-AIoT/ameba-toolchain/releases/download/prebuilts-v1.0.3/prebuilts-linux-1.0.3.tar.gz
tar -xzf prebuilts-linux-1.0.3.tar.gz
也可以使用阿里地址：
wget https://rs-wn.oss-cn-shanghai.aliyuncs.com/prebuilts-linux-1.0.3.tar.gz
后面交叉编译工具也会下载到这个路径，可以修改下权限，避免下载失败：
chmod 777 /opt/rtk-toolchain
4、安装依赖库
sudo apt install libssl-dev libncurses5
5、配置环境
进入 SDK 根目录，运行 ameba.sh 脚本，自动配置环境变量：
source ameba.sh
6、安装工具链
第一次编译项目时被自动安装到默认路径下： /opt/rtk-toolchain
cd amebadplus_gcc_project
build.py
工具链压缩包默认托管在 GitHub 上，首次编译时会尝试从 GitHub 下载工具链压缩包。
如果不好访问Github，可以访问阿里云地址：
build.py -D USE_ALIYUN_URL=True
三、点灯
每次进入开发环境先需要输入：source ameba.sh
新建led_test目录：
1、led.c
#include "ameba_soc.h"
#include "gpio_ext.h"
#include "os_wrapper.h"
#include <stdio.h>
void raw_gpio_demo(void)
{
/* Enable GPIO function and clock */
// RCC_PeriphClockCmd(APBPeriph_GPIO, APBPeriph_GPIO_CLOCK, ENABLE);
printf("example_raw_gpio_light_weight\n");
GPIO_InitTypeDef GPIO_InitStruct_LED;
// init LED control pin
GPIO_InitStruct_LED.GPIO_Pin = GPIO_LED_PIN1;
GPIO_InitStruct_LED.GPIO_Mode = GPIO_Mode_OUT;
GPIO_Init(&GPIO_InitStruct_LED);
GPIO_InitStruct_LED.GPIO_Pin = GPIO_LED_PIN2;
GPIO_Init(&GPIO_InitStruct_LED);
GPIO_InitStruct_LED.GPIO_Pin = GPIO_LED_PIN3;
GPIO_Init(&GPIO_InitStruct_LED);
GPIO_InitStruct_LED.GPIO_Pin = GPIO_LED_PIN4;
GPIO_Init(&GPIO_InitStruct_LED);
GPIO_InitStruct_LED.GPIO_Pin = GPIO_LED_PIN5;
GPIO_Init(&GPIO_InitStruct_LED);
while (1) {
GPIO_WriteBit(GPIO_LED_PIN1, 1);
GPIO_WriteBit(GPIO_LED_PIN5, 0);
rtos_time_delay_ms(1000);
GPIO_WriteBit(GPIO_LED_PIN1, 0);
GPIO_WriteBit(GPIO_LED_PIN2, 1);
rtos_time_delay_ms(1000);
GPIO_WriteBit(GPIO_LED_PIN2, 0);
GPIO_WriteBit(GPIO_LED_PIN3, 1);
rtos_time_delay_ms(1000);
GPIO_WriteBit(GPIO_LED_PIN3, 0);
GPIO_WriteBit(GPIO_LED_PIN4, 1);
rtos_time_delay_ms(1000);
GPIO_WriteBit(GPIO_LED_PIN4, 0);
GPIO_WriteBit(GPIO_LED_PIN5, 1);
rtos_time_delay_ms(1000);
}
}
int example_raw_gpio_light_weight(void)
{
if (RTK_SUCCESS != rtos_task_create(NULL, "RAW_GPIO_DEMO_TASK", (rtos_task_t)raw_gpio_demo, (void *)NULL, (128 * 16),
(1))) {
printf("Create RAW_GPIO_DEMO_TASK Err!!!\n");
}
// rtos_sched_start();
return 0;
}
2、led_example.c
#include "gpio_ext.h"
void app_example(void)
{
example_raw_gpio_light_weight();
}
3、gpio_ext.h
ifndef GPIO_EXT_H
#define GPIO_EXT_H
#include "platform_autoconf.h"
#if defined (CONFIG_AMEBADPLUS)
#define GPIO_LED_PIN1 _PB_17
#define GPIO_LED_PIN2 _PB_18
#define GPIO_LED_PIN3 _PB_19
#define GPIO_LED_PIN4 _PB_20
#define GPIO_LED_PIN5 _PB_21
#define GPIO_PUSHBT_PIN _PA_12
extern int example_raw_gpio_light_weight(void);
#endif
4、CMakeLists.txt
