Initk in serial monitor after uploading OpenCat code

After uploading the first round, you need to enter y or n in the serial monitor to the question "Reset joint offsets? (Y/n)" and let it finish saving all the parameters.

If you have already tried that, use another test in OpenCat/moduleTests/testI2cEEPROM to check if the I2C EEPROM works correctly. If the program returns chaotic characters, you can write to support@petoi.com to request a replacement board.

As I have read before, i never see "Reset Joint offset". Here is what I get from the eprom test:

�   � * B  : �   � , @  9

� � � / > " 8 � � � � 0 ; ) 7

� � � � 2 8 / 5 � �

The complete output should look like this. The random characters at the beginning and end don't matter.

If your board is not printing the contents correctly, I'm afraid the EEPROM is corrupted. If it's correct, we can move on to other causes, probably in the software configuration.

I tried the ASCII Table example with the same "initk" results. I then tried that example with an Adafruit Metro Express board and it worked fine. Obviously I am unable to upload to the NyBoard. The board type is set to "Arduino Uno" Is there some other type I should try, or some other setting?

When I upload, I don't get any messages on the output, just "upload complete". When I do that with the Adafruit Express, I get:

Could the boot loader be corrupted somehow???

Maybe. Do you have another Arduino to perform these operations to recover the bootloader? If not, you can contact support@petoi.com to request a remote desktop session or a replacement board.

switch is set to arduino. I tried entering "Y", but I get this constant stream of "initk" filling up the serial monitor.

Could you take a screenshot of the complete output since booting up? Is there anything connected to the I2C grove socket with SDA and SCL pins?

Nothing connected to IC2-completely stock board out of the box
