Is anyone using a lockable Teensy 4.1 in production? I am starting to produce my Teensy 4.1 based product and was curious as to what the most optimal workflow is for programming and securing the Teensy. It appears that part of this process has to be done from the Teensyduino "security" window. Do I sit down with a box of Teensy 4.1s and start running the fuse write sketch, followed by the lock security sketch on each Teensy 4.1? Then go back and program them all with my encrypted hex file using the Teensy Loader? Any advice appreciated. I just want to do 100 of these at a time in the most efficient way possible. Thanks.
