## 门锁开发环境搭建
|
|
|
|
|
|
|
|
|
|
|
|
安装如下 python 环境：
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
sudo apt-get install lz4 unzip python3-pip
|
|
|
|
|
|
pip3 install yoctools # 安装在 ~/.local 目录下
|
|
|
|
|
|
|
|
|
|
|
|
# Ubuntu下product实际为product64
|
|
|
|
|
|
cd ~/.local/bin
|
|
|
|
|
|
ln -s product64 product
|
|
|
|
|
|
|
|
|
|
|
|
# 以下两条命令打印版本，验证是否安装成功，如无版本信息输出，最好重启一下机器。可能安装yoctools后，可能yoc、product还找不到
|
|
|
|
|
|
yoc -V
|
|
|
|
|
|
product version
|
|
|
|
|
|
|
|
|
|
|
|
# 将 python 软链接定向为 python3
|
|
|
|
|
|
cd /usr/bin
|
|
|
|
|
|
ln -s python3 python
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
原门锁构建环境应该是采用 CenterOS 搭建的，所以很多脚本使用的是 `sh`，在 Ubuntu 环境下，需要注意构建输出，一旦出现疑似脚本错误的问题，可以将脚本开头的 `#/bin/sh` 改为 `#/bin/bash` 再重试。例如脚本文件 `Xuantie-900-gcc-elf-newlib-x86_64-V2.6.1/bin/riscv64-unknown-elf-g++`。
|
|
|
|
|
|
|
|
|
|
|
|
修改编译器位置，我习惯于将编译器独立于项目工程之外：
|
|
|
|
|
|
|
|
|
|
|
|
```makefile title="solutions/smart_doorbell/Makefile"
|
|
|
|
|
|
HOST_TOOLS := /opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.6.1/bin
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
上述步骤执行完毕之后，即可编译打包：
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
2024-08-05 17:42:27 +08:00
|
|
|
|
./boot-rebuild.sh # 编译boot
|
2024-05-31 00:45:46 +08:00
|
|
|
|
./rebuild-app.sh y L015 V200 R002 # 编译烧录固件
|
2024-07-23 20:03:19 +08:00
|
|
|
|
./rebuild-app-ota.sh y L015 V200 R002 14 # 编译OTA固件，11为OTA版本号
