Loading code to HCS12C64CFAE

Hey guys,

i´m quite new to microcontroller programming. What i´m trying to do is programming a HCS12C64CFAE with latest Codewarrior version.

The microcrontroller is installed on the megasquirt EFI board ( Open source fuel injection control).

To start i was using the wizard to creat a simple project with a blinking LED. The first thing i recognized was that i wasn´t able to choose my exact processor. Only HCS12C64CFA16 or ..CFA25 to choose. So i tried with both.

After making and starting the debugger to download the Code the following Elf Loader Error occured:

Error while writing to 3C8000...3C8200

Information: No memory at this address.

At this address the flash memory is allocated as far as i know. I wonder why this tutorial project down´t work here ?

Mybe someone can help me as a beginner .P

Greetings

E stands for Environment, ie RoHS. It doesn't affect any functionality. After the E in the partnumber you should have either 16 or 25, telling what bus frequency the part is capable of.

There are many possible reasons why you can't download your code. Page 3C should indeed be valid for C64.
