?
I'm following the Main Board build instructions. The first tests went well, i.e. 3.3 and 5v tests.
On the next test, i.e. loading the i2cscan.ino, the serial monitor reported No I2C devices found. However, in another popup window, it said Press Button on Teensy to manually enter Program Mode, with i2scan.ino.hex 1% used on the status line. With the audio hat on top of the Teensy 4.1, I cannot access the "button". Should I remove the Teensy from the Main board, remove the Audio Hat, and then program the Teensy by itself first?
