esp-at固件编译流程

1. 源码获取

首先使用git-bash拉取esp-at代码

git clone https://jihulab.com/esp-mirror/espressif/esp-at.git

切换到你想要编译的固件版本

git checkout release/v3.3.1.0

切记一定要使用git命令拉取，否则以下流程都不能执行！

2. 工程环境依赖安装

cmd 打开终端，切换到工程目录

安装当前工程第三方环境依赖

python build.py install

2.1 常见问题解决

2.1.1 网络环境问题

如果提示网络错误，请关闭相关代理软件

如果中途下载失败还需要重新执行

python build.py install

3. 工程配置

python build.py menuconfig

3.1 常见问题解决

3.1.1 如果提示以下错误需要配置idf环境

执行以下命令:

C:\projects\esp_3.3.1.0\esp-at>cd esp-idf

C:\projects\esp_3.3.1.0\esp-at\esp-idf>export.bat
Checking Python compatibility
Setting IDF_PATH: C:\projects\esp_3.3.1.0\esp-at\esp-idf

Adding ESP-IDF tools to PATH...
Not using an unsupported version of tool cmake found in PATH: 3.29.0.
    C:\Espressif\tools\riscv32-esp-elf-gdb\12.1_20231023\riscv32-esp-elf-gdb\bin
    C:\Espressif\tools\riscv32-esp-elf\esp-2022r1-11.2.0\riscv32-esp-elf\bin
    C:\Espressif\tools\cmake\3.24.0\bin
    C:\Espressif\tools\openocd-esp32\v0.12.0-esp32-20230921\openocd-esp32\bin
    C:\Espressif\tools\ninja\1.10.2\
    C:\Espressif\tools\idf-exe\1.0.3\
    C:\Espressif\tools\ccache\4.6.2\ccache-4.6.2-windows-x86_64
    C:\Espressif\python_env\idf5.0_py3.10_env\Scripts
    C:\projects\esp_3.3.1.0\esp-at\esp-idf\tools

Checking if Python packages are up to date...
Constraint file: C:\Espressif\espidf.constraints.v5.0.txt
Requirement files:
 - C:\projects\esp_3.3.1.0\esp-at\esp-idf\tools\requirements\requirements.core.txt
Python being checked: C:\Espressif\python_env\idf5.0_py3.10_env\Scripts\python.exe
Python requirements are satisfied.

Detected installed tools that are not currently used by active ESP-IDF version.
For removing old versions of ccache, dfu-util, esp-clang, esp-rom-elfs, esp32ulp-elf, ninja, openocd-esp32, riscv32-esp-elf, riscv32-esp-elf-gdb, xtensa-esp-elf, xtensa-esp-elf-gdb use command 'python.exe C:\projects\esp_3.3.1.0\esp-at\esp-idf\tools\idf_tools.py uninstall'
For free up even more space, remove installation packages of those tools. Use option 'python.exe C:\projects\esp_3.3.1.0\esp-at\esp-idf\tools\idf_tools.py uninstall --remove-archives'.


Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build


C:\projects\esp_3.3.1.0\esp-at\esp-idf>cd ..

3.1.2 提示A fatal error occurred: No module named 'xlrd'表示你环境有些没有下载完全

需要再重新执行python build.py install

最后再执行python build.py menuconfig

4 工程编译

python build.py build
