 If you run the given command and see errors such as "Failed to connect", there might be several reasons for this. One of the reasons might be issues encountered by ``esptool.py``, the utility that is called by the build system to reset the chip, interact with the ROM bootloader, and flash firmware. One simple solution to try is manual reset described below, and if it does not help you can find more details about possible issues in `Troubleshooting <https://github.com/espressif/esptool#bootloader-wont-respond>`_.
