i'm using MC9S12XF512 devices, trying to store small piece of data in non-volatile memory.
tried to adapt code for different devices but the most i could achieve is to store/read data in debug mode.
no success when not in a debug mode.
basically the idea is to start running running a device and once a switch is ON, store a byte of data in a non-volatile mem. Then power cycle, check memory, data is safely written in the memory.
perhaps there are people who have done it hundreds of times, so an idea/advice would be very helpful.
Solved! Go to Solution.
Thanks for that.
I've just managed to get it working with AN3961SW & AN3961.
Will try now bootloaders that you suggested, I think if I combine two of those I'll get pretty much what I was expecting.
