Currently I have mc9s08ac128 microcontroller. What I'm trying to is to get full memory dump via USBDM, however with no luck. I've been searching the internet for exact memory addresses which should be read. I've tried many different cases but nothing seems to work.


My workflow looks like this:

  1. I reset mc9s08ac128 microcontroller to stock with my other programmer.
  2. I read some of the memory addresses with USBDM.
  3. Then I write the memory addresses back to the microcontroller.

But when I try out the microcontroller, it's not working. Reading and writing proccesses work, I don't get any errors.


So my question is: What exact memory addresses should read so that I would be able to flash it back after reading?
