Re: minicom can't connect serial port (UART)?

Hello, I have just bought the ESP32 Wrover Kit and try to compile the first example (hello_world). I am having quite the same issue, I have configured the serial port through make menuconfig config to /dev/ttyUSB1 Then when doing command make flash (it is quite long, more than 10 min by the way...) ...
