I am beginning to have a situation... The NXP LPC2148 microcontroller we have used and developed for several years has reached the "Not Recommended for New Design" stage. This means I have some time to work on the replacement of the micro but not unlimited time.
What I would like to do is migrate to the ARM Cortex family, especially the M3 or M4 variant. The problem I have found is there seems to be very little documentation regarding this process. Somewhere there must be some information,examples and/or recommendations regarding the migration from the ARM 7 to The ARM Cortex family.
Do you have any information? Can you point me in the direction of some information?
