As I have read before, i never see "Reset Joint offset". Here is what I get from the eprom test: 0 H z , t h e f r e q u e n c y o f m i d d l e D ( D 4 ) i s a p p r o x i m a t e l y 2 9 3 . 6 6 5 H z .

Yes, stuck at "load skills" even after reset yes, "#define MAIN_SKETCH" is commented out Switch is set to "Arduino"

Some PROGRESS: I was able to upload a new boot loader, and then upload OpenCat again. This time the serial port showed: k Init IMU Init servos: 25.00MHz Load skills rather than the expected "Reset joint offsets? (Y/n)" I was also able to upload the buzzer test which now works.

Could the boot loader be corrupted somehow???

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: Sketch uses 11076 bytes (4%) of program storage space. Maximum is 262144 bytes.

OK, I attempted to upload the ASCII example, and got the same "initk" result coming back at 115200 baud. So clearly I am not actually uploading, even though I get no errors. I am able to upload to an adafruit metro express without issues. Is the board type designation correct as "Arduino Uno" for the NyBoard?

I also attempted to upload "test buzzer" but the serial output was the same "initk". No errors on the upload, just "Done Uploading". Do I need to install the OpenCat folder as a library in the arduino IDE

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

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