No other files are required. Unfortunately, in my world, the smallest embedded system isn't of interest. We need something a bit larger. That threaded program needs a data store for persistant data. > the FreeBSD system > detected the fact that the bike was turned off and went through it's > shutdown sequence, closing the video file which was on CF (not NAND > where the OS was) and then when the buffers were flushed, it toggled > an output bit which opened a relay contact and powered itself down. I guess you missed the discussion earlier where it was pointed out that there are significant applications in which CF is not an available option. If you didn't have CF on the device, but you did have NAND, (which is where we are in smartphone land) you'd need a NAND based file system, for the data that has to persist across phone shutdowns.Received on Tue May 30 2006 - 05:37:29 UTC
