【求助】如何编译OTA时的加密固件

[linshc]

使用的IDF为5.1.2,在新版OTA例程中，有个pre_encrypted_ota示例，是用来加密OTA的固件的。我将他整合到了自己的工程中。
问题：
1.添加了加密组件之后，我再main->CMakeLists.txt中添加以下生成加密OTA固件的命令。第一次编译时能够生成加密固件。但第一次之后，再编译固件时，就生成不了加密固件了。请问我该怎么解决，达到每次编译都能生成最新的加密固件？

Code: Select all

create_esp_enc_img(${CMAKE_BINARY_DIR}/${CMAKE_PROJECT_NAME}.bin
    ${project_dir}/rsa_key/ota_private.pem ${CMAKE_BINARY_DIR}/${CMAKE_PROJECT_NAME}_secure.bin app)

每次编译前都删除 build/ 目录呢？
请参考示例添加 cmake、yml 文件中的内容。 https://github.com/espressif/esp-idf/tr ... d_ota/main

1.每次都删除build目录，编译时间太长了。我之前尝试删除xxx_secure.bin文件，可以每次都生成最新加密固件，但现在又不行了。我看到编译时，不会每次都运行main/CMakeLists.txt这个文件
2.我是按照示例添加的cmake和yml文件，你看下是否有问题

您好请问这个问题有没有跟进？
我在测试这个example https://github.com/espressif/esp-iot-so ... th/ble_ota
也遇到了同样的问题：除非删除加密固件，否则在编译时加密固件不会自动更新。

想每次都运行 CMakeList 可以把 “idf.py build” 改成 “idf.py reconfigure build”
