I'm looking for some advice here. I have a configuration of ~30 Teensy3s that need to be programmed in the field (harsh outdoor environment). I was planning on using a beater laptop to walk to each installation and upload new programs as needed. I'm thinking that there must be a simpler way and was wondering about R-Pi. I'm finding some conflicting info on if you can run the loader on R-Pi. My idea is to have no-display, just a battery and an R-Pi, plug it into the Teensy and press reset. The target board has a status display that I can use to show that it's been properly received. I can do the work back in a safe space and then upload it to this mobile programmer there. It needs to be as simple as possible.

Has anyone had any luck working with the loader on R-Pi?
