After successful uploading of program following message appears.After successful uploading of program following message appears.
esp32 Boards must be installed under board manager, it is recommended to use the latest version of esp32 board driver for Arduino.
Due to installation of different drivers and older versions of libraries, Arduino fails to upload the program to the controller. In most cases it is due to failure to enter boot mode of the device. The device can be forced to boot mode by connecting the BOOT IO0 of the expansion port to the GND pin with a jumper wire. Arduino is able to upload the program to controller while the controller is in boot mode. After uploading the program , the connection between the BOOT IO0 and GND must be removed to run the uploaded program.
