Help 16265957 Disassembly

Postby nexxtres » Thu May 22, 2014 11:54 pm

Hello, I started again to try to find my maps in ECM 16265957 code FDST.

I was experimenting with the DHC11 but have not been successful. Are still many areas without disassembly.

Someone could help me with this step?

Thanks.

I havnt used DHC11 but I believe you'll need to define the reset vector, and 2 interrupt handlers so that it can disassemble from all the entry points.
Have you read the FAQ? For lots of information and links to significant threads see here: viewtopic.php?f=7&t=1396

You know how the vectors defined in DHC11? or recommend another disassembler? Thanks

I normally use M6811DIS. Here is an example with the control file (vectors and other entries) .. viewtopic.php?f=27&t=2439&p=23775&hilit=disassembly#p23775

If you want to use DHC11, try adding the text in the attached file. It has all the normal vectors, as well as labels for all the ports, etc.

...or use this control file with DHC11 and you should get a full disassemble. Part of the trick is to look at the code anywhere the disassembler tells you:

Indexed Call/Jump at $XXXX, may require a vector table

and add a vector table (as seen below the "subroutines" comment in my file)
