Hi,
I have been away for quite awhile but I am back! I just got my first two Teensy 4.0 boards from Adafruit, and I have Circuitpython one one.
However, the second one is totally unresponsive. It acts like it is dead, but I do not understand how that can be. All the soldering looks good, and I just resoldered all the pins to be sure. It still acts like it is dead. I can not get any response from it and it will not allow me to load Circuitpython on it. I also can not access it from the Arduino 1.8.13 IDE with the latest Teensyduino (just downloaded) installed.
Does anyone have an idea what else might be wrong? I got the other Teensy 4.0 working right away, so I am confident that this one should be working too.
Now, neither one is working! This is very odd, especially since one has been working perfectly with Circuitpython. I am completely mystified!
Update: I am using the Teensy Commandline loader v2.2
