or run ’idf.py -p PORT flash’
If there are no errors, the build will finish by generating the firmware binary .bin file.
2.4.5 Flash onto the Device
Flash the binaries that you just built onto your ESP32-WROOM-DA module by running:
idf.py -p PORT [-b BAUD] flash
Replace PORT with your module‘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
. If everything goes well, the “hello_world” application starts
running after you remove the jumper on IO0 and GND, and re-power up the testing board.
Note:
The option ‘flash’ automatically builds and flashes the project, so running ‘idf.py build’ is not necessary.
