GCC suppot for Motorola 68HC12

mentallysilent · 2006-11-17 05:24:08

hello masters,

I'm trying to get GCC to compile code for Motorla's 68HC12 microcontroller. It seems default arch gcc is not configured for such things and I really dont want to get the old binutils from GNU to make this thing work. Does anyone know what I can do?

Thanks

What's the arch and target for that thing? See my sig, maybe those pkgbuilds can help you?

The target architecture is Motorola's 68HC12 microcontroller with Dragon 12 all on an evaluation board, it is normally used for robotics applications and control systems.
This thing is supported by GNU and I was "trying" to get the GNU embedded toolchain environment going but I get a compile error so that's a no go. Thanks for your reply I will check out your repo. On a different note, I already have the required environment and tool chains on RPM's or Debian .deb format. I was wondering if there is any way I can build an .tar.gz for easy installation on Arch. anyways thanks for your reply.

I was asking for the GNU architecture target name. For example i686-pc-linux-gnu or m86k-unknown-linux-gnu. I can try to get a package going for you if I know that.
If you have a toolchain on another distro, tell me the output of the following:

gcc -v

mentallysilent · 2006-11-17 21:23:26

this is the output of gcc -v

Target: i686-pc-linux-gnu
Configured with: ../gcc-4.0.3/configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --prefix=/usr --enable-shared --enable-languages=c,c++,objc --enable-threads=posix --enable-__cxa_atexit

I'm basically following the instruction here:
http://www.gnu.org/software/m68hc11/

The installation instructions are at:
http://www.gnu.org/software/m68hc11/m68 … t_ptc.html

building this for arch would be most kind of you.

Actually I meant the output of the cross gcc for m68hc12.
Nevertheless, the links you provided are more than enough info for building the toolchain. I am currently compiling binutils, gcc is coming later but I'll skip on the newlib target. If you have the time please use the repository and get the packages once they are available and report back if they were of any help.

mentallysilent · 2006-11-18 22:48:01

I'm sorry for the wrong info, I'm a big fat noob. But yes basically the instructions are there in those URLs I posted. When compiling binutils, I came across a very peculiar error originating from one the header files. Hopefully you won't encounter it. As for checking the package I will definitely test it once it comes on your repo. And may I ask what is contained in newlib? Is it not needed for building the toolchain? And thank you again, you're saving me from having to code in assembler which is a daunting task.

Uploading all packages right now, A minor issue I've had in binutils 2.17:

Not much as you can see. heh

[edit]
I already uploaded the pkgbuilds.

And to your question what newlib is, well. It's a small library that you can use instead of big stuff like glibc I guess. I have never worked with it really...

Nice! Thanks a bunch.

Hopefully GCC and GDB are next

ignore the mips in the pkgdesc. ;p

Hmm, I will see what I can do tonight. Say, did you ever try that m86hc1x simulator? Does it work well? I'd go and look for sample code to compile and run in that to fix the problems.
