Petoi Camp

Hello, I have been trying to set up Nybble but am unable to get past the first stage of initializing the board using Arduino IDE. I have board version V1_1. I am able to upload Opencat.ino and reset the joints but it never asks me to calibrate the IMU. I have attached what the serial montior is printing out below. I have tried burning the bootloader and replugging everything. Also, I have the Petoi lithum battery and it is fully charged. Due to this failure, the servos will not calibrate or move. I have tried using the mobile app as well.

Hey everyone, somethink went wrong with my 1 day old brittle. It´s my first robot and i´m fairly new to the topic at all. I tried to upload my first sketch step by step with this tutorial: https://docs.petoi.com/arduino-ide/upload-sketch-for-nyboard Everything works fine until step 10 - i uploaded the sketch with the now again uncommented "#define MAIN_SKETCH" - nothing happend after that (the upload dont´t throw any failure message to me). The tutorial says: "Open the serial monitor. When the serial monitor prints "Ready!", the robot is ready to take your next instructions." but there was nothing - completly empty serial monitor since then, no matter what i do. Every next try to upload a sketch brings the "not in sync error" message, so i tried to repair the Bootloader with this Tutorial: https://docs.petoi.com/technical-support/burn-bootloader-for-nyboard I have an additional Arduino Uno R3 and followed the instructions step by step - everything works fine until i clicked "Burnt Bootloader". The following error message appeared and i am completely lost with the "Failed chip erase" message at the bottom.

Thank you. Failed chip erase: upload error: exit status 1 Hope anyone has an idea what i can try next, i´m a bit frustrated right now cause my Bittle seems a bit "dead", LEDs a lighting but no beep sound at power on and no movement :( (I´m on a Mac Book Pro M1, in case this is important) Greetings! Stefan

i followed the instructions to upload OpenCat (the latest version from github), everything went as expected now the bittle doesnt seem to boot. turning the battery on turns the blue and yellow lights on the board but nothing else happens. it makes no sounds and none of the servos move. it doesn not respond to the IR controller it does nothing after connecting it to the desctop app, calibration, stand etc does nothing. have i bricked it? how do i fix it? thanks
