Get Started
This command will compile the application and all ESP-IDF components, then it will generate the bootloader,
partition table, and application binaries.

Project build complete. To flash, run this command:
16
../../../components/esptool_py/esptool/esptool.py -p (PORT) -b 921600
17
write_flash --flash_mode dio --flash_size detect --flash_freq 40m

19
build/partition_table/partition-table.bin
20
or run ’idf.py -p PORT flash’
If there are no errors, the build will finish by generating the firmware binary .bin file.
3.4.5 Flash onto the Device
Flash the binaries that you just built onto your module by running:
1
idf.py -p PORT [-b BAUD] flash
Replace PORT with your ESP32-S3 board’s serial port name from
You can also change the flasher baud rate by replacing BAUD with the baud rate you need. The default baud
rate is 460800.
For more information on idf.py arguments, see
.
Note:
The option ‘flash‘ automatically builds and flashes the project, so running ‘idf.py build‘ is not necessary.
When flashing, you will see the output log similar to the following:
