Flashing esp-idf project : no output on monitor



  • Hello,
    I have made a project for the wrover esp32 board, and would like to port it to the pycom gpy(I have the extension board v3.1) . I read that to be able to do that, i just had to make a connection between p2 and gnd, so that's what i did. I am trying with the hello-word example from the esp-idf directory. The program seems to be flashed, but then the monitor starts and there is no output at all. I set the baudrate to 115200. Could you help me ?

    ~/esp/esp-idf/examples/get-started/hello_world$ make flash monitor

  • My bad, apparently I messed up the flashing process: in order to flash an esp-idf project, one must make flash with the strap, then remove the strap, push reset next to the led, then make monitor, and a keystroke to make it appear on the screen.
