I have a question about how the boot up process works.

Does your code need to be in the mbed's flash drive or is it written to the 1768's flash memory?  Does it stay in program memory or is it written over every time the mbed starts up?

It's written to the 1768's flash. It's done when 1) you press the reset button on the board and 2) the interface chip finds a .bin which is newer than the currently flashed one.

Ok.  Thanks.  My next question is this.  I notice that if I delete all the bin files off the mbeds flash drive nothing runs when I restart the chip.  Does that mean that it needs a program on the flash drive to run a program even if it still has one in the 1768's memory?

Hi Chris,

I just added this page:

Hope that explains things.

Thanks Simon, that was just what I wanted to know.  There really should be more pages like that.
