A message of Done compiling will be displayed in the information window after few seconds if
your operation is right. The message showed a successful compilation. Please backup to check
whether the processing is completed if any error.
After the programing, please choose Tools->Board-> FireBeetle-ESP32. In general, this step
performs only once on first use if you would not change the board.
Switch to Tools->Port, according to the number of serial port shown in the FireBeetle Board-ESP32,
we should choose COM3 as the communication port. The communication port appears only
when the development board has connected to a computer and been successfully recognized.
We should confirm the communication port carefully before every uploading, for a development
board may occupy different ports after insertion and extraction.
After the choice of COM, the information of board and port shows in the lower right of the
window.
