Some layers may be difficult to prove but that should not make it impossible to do good work. Something along the lines... If Given: uboot is trusted. If Given: USB IO is trusted to devices ...UVW, XYZ. The value of accepting some "Givens" is that other levels of work can move forward on a very inexpensive platform. As a student platform the R-Pi is interesting because the student has a worthy (sufficiently interesting) platform to abuse for less than the price of a modern text book. Pop out the memory card reload it and start over. The students laptop has not crashed. There is an old adage that to work on a car at home you need to have a second car available to go and get parts. With the R-Pi spare flash memory cards and USB memory give that spare vehicle to go and get parts.... Have fun. -- T o m M i t c h e l l
