A non-stop buzz come from the board after power-on

NyBorad V0_2


WriteInstict.ino was uploaded as V0_1 (my mystake) but everything passed well

- Instincts are loaded

- MPU is calibrated

- Joints are callibrated (bcs the wiring schema is for V0_1 was used) and saved


I took out batteries and left my cat for the night.


On a next day I wrote done Nybble.ino (still as V0_1) but IR didnt work


So I again took out batteries and left my cat for the night at a rest postion.


On a 3rd day I put a full charged non-protected batteries and power on my cat


- A non-stop buzz come from the board after power-on


- The blue led and the green led are constantly on


- if FTDI is pluged (yes, GND to GND) into the board before power on - the PWD and REN leds are constantly on


I see /dev/ttyUSB0 under my Ubuntu, port speed 57600 but cant upload any sketch nor any bootloader now

when you upload, is the battery still powering the board? The meowing and the numbers(287, 265...) is the low voltage alarm.
