The upload went well. The tar created the directory d:/usr/.... In the usr/bin the are a lot of variations of m68hc11-elf-....... But the file I expected m68hc11-elf-gcc has the extention .exe and there is no one named without extention. What am I doing wrong?

I think there are issues with cygwin64. You need to use the 32-bit version. I know that's what I'm using and it works. And there are posts from last year that say the same thing.

@jean, 32 bit version is working without problemen. Thanks

I am using table switching Patrol and LPG. The are some tricks to connect the thermo sensor to the ground for LPG by hardware. Who can help me to do this by software. I need some support where to change and which signals

http://www.msextra.com/tools/ is great. The version of gcc is pretty out of date. Has anyone tried using the latest version of gcc? I like to keep my system managed by dnf as much as possible which is why I ask.

This is the latest version of gcc for s12.

James

Got it. Thanks James!

Actually, I realized that I could probably bundle those tools up into a docker container. Then I could run a simple docker command. I'll post back once I have that working.

I was able to create a .s19 from the ms2extra source with docker!

Here's the Dockerfile I used:

FROM fedora:26

RUN dnf install -y wget
RUN wget -q -O freescale-tools.tgz http://www.msextra.com/tools/s12buildto ... -24.tar.gz
RUN tar --strip-components=1 -zxf freescale-tools.tgz
RUN tar -zxf tools.tar.gz
RUN dnf install -y make which
ENV PATH="/usr/bin:${PATH}"
RUN dnf install -y glibc.i686
RUN dnf install -y zlib.i686
VOLUME ["/host"]
WORKDIR /host

In the directory I had my Dockerfile in I did this:

docker build -t freescale-tools .

After changing BINDIR to /usr/bin/ in the Makefile, I ran the following commands in my ms2extra directory:

docker run --privileged -v $PWD:/host freescale-tools make
docker run --privileged -v $PWD:/host freescale-tools chmod -R `id -u`:`id -u` .

And voila! megasquirt2.s19 was in my current directory!

I like this approach as I don't have to muck with / on my system.

I'll also add that I loaded the .s19 file to my MS2 and it worked flawlessly.

James, would it be possible to include that Dockerfile in with the sources? Or would it violate the license if I published that Dockerfile as an image on dockerhub? It would be cool if `msextra-tools` were up on the hub.

I'm not sure I understand the purpose of this 'docker' ?

The MS2/Extra build is fairly simple driven by a Makefile. If you have a different tools path, you can edit the Makefile and set your paths in the PROGPREF line.

James

Yea, the Makefile is indeed pretty straight forward. I like using docker containers because I can avoid installing tools in global paths. Docker commands are run in a container, and containers are like light weight VMs.

Just stumbled upon this site and thought I'd share. Lots of relevant info: http://www.seattlerobotics.org/encoder/ ... ncoder.htm

When running the "make release" in cygwin does it spit out how much ram and flash the new .s19 file uses?

Take a look in the top of the *.dmp for the flash section usage, you'll need to cross reference memory.x also. Variable allocation in RAM you can find in the *.map file, but that doesn't tell you the required stack space.

James

well i am keep getting an error
$ make release
-bash: make: command not found

I have windows 10 and the latest 32bit cygwin and i have thes12buildtools-win32-2012-10-24 extracted and it is in the C:/cygwin/usr/bin folder

m68hc11-elf-gcc is in the folder when i checked

I included a screen shot of the issue. lol not sure where i went wrong.

I have folder that the files to be compiled are C:/cygwin/trans

i did " cd C:/cygwin/trans " and then i typed "make release". I know im doing it wrong lol

Thanks apparently i'm challenged. lol

Nelson

When you installed cygwin, did you select the package that includes "make" ?
I'm guessing that command would normally be in /usr/bin

James

nope.lol that makes sense.lol

I think i found the package I believe it is just make package. ill install this one.

Looks like the make command works i get a error 127 when compiling using non edited firmware. guessing i need to adjust make file. i was just testing Thanks for help!
