Step 8. Build The Project; Step 9. Flash Onto The Device - Espressif ESP32-S2 Programming Manual

Chapter 1. Get Started

1.12 Step 8. Build the Project

Build the project by running:
idf.py build
This command will compile the application and all ESP-IDF components, then it will generate the bootloader, par-
tition table, and application binaries.
$ idf.py build
Running cmake in directory /path/to/hello_world/build
Executing "cmake -G Ninja --warn-uninitialized /path/to/hello_world"...
Warn about uninitialized values.

[527/527] Generating hello_world.bin
esptool.py v2.3.1
Project build complete. To flash, run this command:
../../../components/esptool_py/esptool/esptool.py -p (PORT) -b 921600 write_flash -
-flash_mode dio --flash_size detect --flash_freq 40m 0x10000 build/hello_world.
→
bin build 0x1000 build/bootloader/bootloader.bin 0x8000 build/partition_table/
→
partition-table.bin
→
or run 'idf.py -p PORT flash'
If there are no errors, the build will finish by generating the firmware binary .bin files.

1.13 Step 9. Flash onto the Device

Flash the binaries that you just built (bootloader.bin, partition-table.bin and hello_world.bin) onto your ESP32-S2
board by running:
