very simple 68k tini board

(1/1)

DiTBho:


I'll point it out to you. Maybe someone will be interested.

See here (kind of Wikipedia)

For glue logic it only uses two PALs to program with a Windows software (free download).
Feally very simple, I didn't understand if there are PCB gerbers and/or a KiCAD or EagleCAD project  :-//

I haven't yet investigated too much, I found it while looking for information on the toolchain for m68k to integrate with a libc {uclibc, musl, ...}.
And found that, among the various entries in Wikipedia, there is a link to a github repo, here, for building a complete toolchain, including not only gcc but also a second C compiler Vbcc!!!


Enjoy it, happy hacking  ;D

I'm working on my own 68k8 (currently on a breadboard).  I was able to "get to blinky" remarkably fast given that I'm new to 68k hardware design and assembly.   Many thanks to Jeff Tranter's blog, his youtube video, and the Alan Clements book.

Thankfully I haven't had to build gcc; just installed (on Linux):
      binutils-m68k-linux-gnu-0:2.37-3.fc35.x86_64
      gcc-m68k-linux-gnu-0:11.2.1-1.fc35.x86_64

And, for a minimal C environment, see here; specifically the "standalone" directory.
For my initial LCD "hello world" program, I haven't even had to compile the minimalist libmetal library yet; just copied over a couple of .S files.

See, I built a builder to build { binutils, gcc } toolchains, not only for 68k but also for 68hc11, and, among the dead things, also 88k.
it works very well, but i hacked gcc very deeply. some patches i could have avoided. this is what i understand looking at toolchain builder like the one used in this project

For me this project has much more importance for that Makefile that you find in the second link that I indicated.
It shows some interesting tricks.

Then I really liked the approach to pal, with everything you need, and it's really little  :D

DiTBho:
Is anyone interested in making the PCB for this tini project?
