Using a Mac M1 max laptop running arduino 2.0 IDE. I see the serial board as /dev/cu.usbserial-210. I configured it as an "arduino Uno" board. Serial monitor set to 115200baud/no line editing. commented out the code as suggested and uploaded to the board with no errors.
The serial monitor outputs "initk" over and over again.
Stuck at this point... any suggestions?
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.
