Link errors on port from DP256 to DJ128 - galenpatrickogrady - Jun 13 10:51:00 2005
I'm using Codewarrior 2.0 and am doing my development with a DP256
part. The production version won't need all the bells and whistles of
the DP256 and so I'm trying to re-build for the DJ128. I've included
the DJ128 rather than DP256 c and h files and reduced the available
pages (in prm file) to match the DJ128.
Problem is I'm getting link errors that I don't know how to
troubleshoot. The errors look like this: "ERROR L1100: Segments
.absSeg265 (0x0) and .absSeg426 (0x0) overlap". Where are the
.absSegxxx entries generated and where are the "placement
instructions" that are causing the problem?
Regards,
Galen.

Hello Galen,
Look at the linker messages: you can map the message to a warning. The
linker option -WmsgSw1100 does this for you.
Then you could check the .map file what is causing your problem.
I guess you have two objects allocated to the address zero (using the
absolute @0x0000 notation.
In the map file you will get the name of the segment/object.

Re: Link errors on port from DP256 to DJ128 - galenpatrickogrady - Jun 14 10:25:00 2005
Looks like the messages were being generated because of the dual
8-bit/single 16-bit register definitions in the DJ processor's .h
file. For example PORTA is defined as 8-bits at address 0 and PORTAB
is defined as 16 bits also at address 0. When I created a "clean"
DJ128 project in Codewarrior, I didn't get these errors because these
messages had automatically been disabled in the linker dialog.
When I disable the linker messages in question, my project build and
runs as expected on the DJ128. The .h file I'm using for the DP256
doesn't have these overlapping definitions and so it wasn't an issue
before.
Wouldn't it be better to define PORTAB as a union with PORTA? I don't
think it would cause these linker errors. Is it possible to nest
union definitions? PORTA and PORTAB are already unions of bits.

Galen

Re: Re: Link errors on port from DP256 to DJ128 - Daniel Friededrich - Jun 14 11:36:00 2005
Yes, using a union is the cleaner solution. This has actually been
changed in the CW for HC12 V3.1 version, I'm not sure of CW for HC12 V3.0.

OT: FAA DER? (cross post from HC908, sorry about that) - Gary Olmstead - Jun 15 11:10:00 2005
Any avionics designers out there? I am in the first stages of a project
that will require the services of an FAA Designated Engineering
Representative. The first thing I found is that they are darned hard to
find, even with Google.
Does anyone out there have any experience with them?

Better than that, there is a 192 page directory on the FAA web site. I
guess when Google didn't turn up anything interesting, I assumed that there
was nothing interesting to be turned up. Guess I needed to sit back and
think, which is what I would have done before Google took over.
Thanks to everyone who helped out.

You can find one near you through your local FSDO. Don't know if the
faa.gov site has a list online or not.
Looking for DO-178B certification, or hardware issues? I work in the field
and would be happy to share some of the trials and tribulations. But I've
never finished my DER certification effort (started, then got side-tracked
by another project).
