The Hello_World Example; Using The Esp32 Download Tool - Espressif ESP-WROVER-KIT Getting Started Manual

!

5.3. The hello_world Example

The esp-idf/examples/01_hello_world directory contains a sample code that can be run
on the ESP32.
1. Using the command terminal, change the current directory to example/01_hello_world:
cd examples/01_hello_world/
2. Configure IDF_PATH:
export IDF_PATH=/home/share/esp-idf-driver/esp-idf
3. Check the IDF_PATH configuration to make sure it is properly set. Failing to set the path
will cause failure to the linking of dependent files later.
echo $IDF_PATH
4. Compile the program to generate BIN files. These BIN files have to be downloaded to
the ESP-WROVER-KIT. Please see Sections 5.3.1 and 5.3.2 for detailed instructions.

5.3.1. Using the ESP32 DOWNLOAD TOOL

Execute the following command in the terminal to make the example project and generate
executable BIN files:
make
Three BIN files need to be downloaded: example/01_hello_world/bootloader/
bootloader.bin, example/01_hello_world/partitions_singleapp.bin and example/
01_hello_world/hello-world.bin. Then, users can flash these BIN files by using the ESP32
