Hi Presto,
Welcome to the forum.
So you have a non-specified Freescale 8-bit mcu which you are trying to read to 'preserve' the code, and the reset vector does not make sense?
I can think of many, many reasons why this is the case.
Could the device be secured against intrusive access?
Might this be a RS08 and the 'reset vector' is not where you think it is (it is not at 0xFFFF)
You have an HC08 in Monitor Mode
Before we all expend lots of energy on this problem, can you please provide the following information
1) Please warrant that this is your application that you are trying to preserve, and that you are not trying to reverse engineer anything. I would not want to help you to do that.
2) Please give us either the device part number (if you know it) or the legend printed on the top of the device. All the details from every line. If you do not know the device part number, please see item 1).
3) The mechanism that you are using to read the device. Mono8, BDM, SEM (if it is a SEM, see item 1))
4) For those of us with analytical brains, what address are you reading, and what values are you getting?
Mark
