Ensure the Arduino IDE connected to the same port the ESP32 is connected to. This is likely to be /dev/ttyUSB0 or /dev/ttyUSB1

Ensure the Arduino IDE is using a good board profile. ESP32vn IoT Uno and DOIT ESP32 DEVKIT V1 have been found to work well.

Add your Linux user to the dialout group permanently with sudo usermod -a -G dialout $USER. To do this temporarily, run sudo chmod 777 /dev/ttyUSB0 and then launch Arduino from the same terminal.

If make menuconfig fails, run: sudo apt install flex sudo apt install bison
