Mega2560 strange behavior

[siejeje]

Hi!

I flashed the Mega2560 board with the latest firmware (standard one not the one for Mux Shield) and after enabling all analog inputs the board spits out messages like crazy. Please watch the video. Nothing is connected to the board except for the usb cable.
Am I doing something wrong here? I did not create custom configuration, just used the hex files from the releases page.
The board I am using is brand new ELEGOO Mega 2560.
BTW. I also tried the firmware with muxsh2 support and it flashed correctly but the configurator will not open, probably because of not enough resources on the board. Right now I'm not able to disable peripherals in the configuration and build the custom firmware.
Any help is appreciated. Thanks

that's normal. connect your analog inputs to ground to stop the messages (ADC = 0). then test each ADC using a single potentiometer

You are correct. Sorry for being noob ;)
