Hello,
I am working on a project where my Feather M0 is supposed to grab data from a bunch of sensors, perform apply a Two Step Kalman Filter to get refine the data it reads in, and print it to an SD card. This project consists of multiple files, compiles normally, and uses only 26% of program storage space. However, when I try to upload it to my Feather, it typically fails to upload and the Feather disconnects from its port. I tried uploading the code from a different PC and I'm getting the same result. I then tried uploading a different (larger) project and managed to get it uploaded and had it running. I'm completely at loss as to what could be causing this and any guidance on the issue would be a great help.
