Re: "Brownout detector was triggered" failure on my ESP32

Your USB port is not providing enough power. Try another port, or else you will need an external power source (perhaps a powered USB hub).

Re: ESP32 Ethernet KIT v1.1 ETH example missing???

The supported platform for ESP32 is the ESP-IDF. You can find an example which will work with your device at https://github.com/espressif/esp-idf/tr ... s/ethernet. Once that code (idf 4.x) makes it into arduino, the device will be supported in arduino.

AFAICT the arduino hal always uses GPIO matrix.

Re: Dual Core share serial

You should set a binary semaphore, and have each processes take the semaphore when they need to write. Then, simply flush the serial object, write, and give back the semaphore. Rinse, repeat.

Re: TCP/IP communication between few ESP32 - memory crash with client.remoteIP()

I am unable to reproduce your problem, but it doesn't really look like it is the remoteIP call causing the crash. Turn on Core Debug Level: Verbose to see if any additional information is available. Put in more debug prints so you can see exactly where the error occurs (log_v is better for this than...

Re: ESP32 unable to execute uploaded program

Hold down gpio0, then press the reset button. This will put it into download mode.
Now you can flash or erase.

Re: Can I change the bootup settings in Arduino IDE? E.g. Boot log or flash mode

You cannot modify the bootloader in arduino-esp32- they are pre-compiled. Use esp-idf or lib-builder if you want more control.
The only interaction you can have with the bootloader is hardware level. That's why there is a strapping pin to disable the logging.
