Yes, all that you mentioned is true, but what you failed to mention is that 1) it is a run-time environment only, 2) it requires another machine running u*x, on which you do all program development and cross-compilation, and 3) you cannot boot it from disks, it has to be down-loaded from the development u*x machine over either a serial line or over Ethernet.
