    Welcome.

    My EPS32 WROOM has broken down.
    I have this error:

    A fatal error occurred: Failed to connect to ESP32: Wrong boot mode detected (0x17)! The chip needs to be in download mode.
    .

    Is it possible to fix it somehow?
    Helpful post? Buy me a coffee.

    Try setting the bootloader mode in the Arduino IDE to the old one. It usually solves the problem.
