So I have a Micromod ATP with a Micromod Teensy processor installed. The issue I am having is that the code I've uploaded only runs when it is booted by connecting to my laptop. When I plug the ATP into external power (5V 1A either through VIN/GND or through the USB-C port) all of the sensor/ATP power LEDs light up, but the code doesn't run.
Interestingly, if I boot it up by plugging in my laptop, connect 5V 1A to VIN/GND, then unplug my laptop from the USB-C port, everything continues working as expected. So it seems like the external power is ok to power the board once the processor has booted correctly.
I assume this is something to do with the bootloader/POST. I feel like this may be something obvious, but I haven't found anything in the documentation matching this behavior.
