ESP32带 log 记录的 malloc 动态申请内存，用于debug 调试查找报错原因

# Hello World Example Starts a FreeRTOS task to print "Hello World". (See the README.md file in the upper level 'examples' directory for more information about examples.) ## How to use example Follow detailed instructions provided specifically for this example. Select the instructions depending on Espressif chip installed on your development board: - [ESP32 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/stable/get-started/index.html) - [ESP32-S2 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html) ## Example folder contents The project **hello_world** contains one source file in C language [hello_world_main.c](main/hello_world_main.c). The file is located in folder [main](main). ESP-IDF projects are built using CMake. The project build configuration is contained in `CMakeLists.txt` files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both). Below is short explanation of remaining files in the project folder. ``` ├── CMakeLists.txt ├── example_test.py Python script used for automated example testing ├── main │   ├── CMakeLists.txt │   ├── component.mk Component make file │   └── hello_world_main.c ├── Makefile Makefile used by legacy GNU Make └── README.md This is the file you are currently reading ``` For more information on structure and contents of ESP-IDF projects, please refer to Section [Build System](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html) of the ESP-IDF Programming Guide. ## Troubleshooting * Program upload failure * Hardware connection is not correct: run `idf.py -p PORT monitor`, and reboot your board to see if there are any output logs. * The baud rate for downloading is too high: lower your baud rate in the `menuconfig` menu, and try again. ## Technical support and feedback Please use the following feedback channels: * For technical queries, go to the [esp32.com](https://esp32.com/) forum * For a feature request or bug report, create a [GitHub issue](https://github.com/espressif/esp-idf/issues) We will get back to you as soon as possible.
