Start by downloading the compiler here and try to compile the latest version of the code. Once you have that start a new thread. And you can search the forum because there is information about what you need to compile the code.

Jean
tried make file under cmd
tried cygwin and am out of inspiration at the moment
a lot of links and foto,s seem to be removed in the post,s
any help

uploaded the file removed the microsquirt code otherwise the file was to big

Do you have a directory "c:/usr/bin/" with an executable "m6811-elf-gcc.exe"? If not can you find where "m6811-elf-gcc.exe" is? If you don't want to have to modify the make files you will need to have the directory so you may need to create the directory and/or move the files.

wat i have now is
C:\msii\compiler\bin\m6811-elf-gcc.exe
C:\msii\ ms2extracode\....
C:\cygwin\.....
i do not have a
C:/usr/bin
i did not do anything with the .exe files in the compiler
can you give me an example of the proper file structuur

[racingmini_mtl]

Create a "c:\usr\bin" directory. Copy the content of "c:\msii\compiler\bin" to the "c:\usr\bin" directory. This should get you going.

still no luck

if you use the zip file from 303s, then you can compile it. No problem there.
Unless you are using 303t, then you can't compile it anymore.

That was what happened to my end here. I just can't compile 303t. It will
spit the errors like you had here.

I'm sorry but the problem is on your end for not using cygwin (or not having it correctly configured) not with the 3.0.3t release. And if you're not using cygwin, did you try the makefile here: http://www.msextra.com/forums/viewtopic ... 20#p243927?

By the way, if you do a diff of the 3.0.3s and 3.0.3t directories you'll see that very few files were changed and that will not prevent you from compiling the code. Or try just copying the file that changed to see what you get.

Yes, that's the file that I tried with no error. Just unzipped it to c:\msii\compiler folder and it's good to go. It's not that simple with 303t. It just won't compile even with nothing touched to it.

I'll try that.

Try with the Makefile.DOS I posted in the 303s topic.

James

Tried but it still wont compile.
From what I can see, there are 2 more additional files in 303t.
1. crc32.s
2. interp.s
those files are also mentioned in the errors. Most probably the makefile is not pointing to those files
which prevent it from compiling.

[Gokart]

Yup... include that files to the makefile and it compiled.

Thank you every one.

[jsmcortina]

How is that different from the Makefile I posted? Adding those two files is exactly what I did.

James

[Gokart]

I might make a mistake by wrongly pasting a different file maybe... sorry.
Now, how on earth to compile a microsquirt file. I still unable to do so.
Even though I did say that it compiled but it was not tally with what you
have in the zipped file. You must have a different routine that make it
not to work with the regular msii file folders.

[MS2tester]

well i have the cygwin going also
think something went wrong with my gnu installation
still have to test the code in the megasquirt

[racingmini_mtl]

So now what you need to do is change the 10 at the end of the lines below to 9 in the file ms2_extra_inj.c

Code: Select all

void add_vetrim(void)
{
	if (outpc.vetrim[0]) {
		//Use trim table
		tmp_pw1 += (((long)tmp_pw1 * outpc.vetrim[0]) / 10) >> 10;
	}
	if (outpc.vetrim[1]) {
		//Use trim table
		tmp_pw2 += (((long)tmp_pw2 * outpc.vetrim[1]) / 10) >> 10;
	}
	if (outpc.vetrim[2]) {
		//Use trim table
		tmp_pw3 += (((long)tmp_pw3 * outpc.vetrim[2]) / 10) >> 10;
	}
	if (outpc.vetrim[3]) {
		//Use trim table
		tmp_pw4 += (((long)tmp_pw4 * outpc.vetrim[3]) / 10) >> 10;
	}
}

and change in the megasquirt-ii.ms2extra.ini file the lines related to trim which have the values

Code: Select all

0.0976562500, 1024.0000,   87.60,  112.40

to

Code: Select all

0.1953125000,  512.0000,   75.20,  124.80

and the lines having

Code: Select all

0.00976562500, 10240.0

to

Code: Select all

0.01953125000,  5120.0

and you'll need to change the vetrim gauges limit from 87,113 to 75,125

That should give you twice the range for the trim but half the resolution

so far so good
now just waiting till all the hardware has come with the mail

[MS2tester]

hi jean
i,m going to start with a fresh megasquirt
to recap these are the parts not installed on the board anymore
i will only be using sequntieel with the peak and hold boards
V3.0
The parts you no longer need are:
D3, D5, D6, D7, D17, D18, D20, D21, C13, C14, Q1, Q3, Q5, Q9, Q10, Q11, Q12, Q13, Q14, Q15, R15, R18, R20, R30, R31, R32, R33, R34, R35, R36, R37, R38.

The picture below shows the placement on the V3.0 board of the 4 injector channels. The standard injector drivers components can be left on the board but will be unused and will not interfere with injector channels 1 and 2. The injectors channels 3 and 4 connect to pads originally used for the MS1 clock circuit and require the removal of those components for proper and safe operation. The injector channel 3 shows 2 pads because they correspond to the same electrical location (use either one). The components to remove are: R21,C20,C21,R22,R23,Y1,C24,C25.
with the modification to the MS2 chip offcourse

[racingmini_mtl]

You don't need the 2 V3.0 injector driver circuits and the clock circuit (never needed with MS2 anyways). The list of components is for these circuits.

[MS2tester]

forgot to ask is injection timing possible with only a 60-2 wheel
i assumed this since ign V6 two stroke is already possible in 2.1.0
i received the boards thx
now just the megasquirt still in customs

[racingmini_mtl]

Injection timing is possible for every wheel mode except distributor and EDIS modes which don't provide any information on cylinder identification.
