Adopt emb.LV to emb.Linux Target ARM9 Prozessor

[Michael.Phillips]

Hi,

This error is most likely due to the fact that the location of the m68k-uclinux-gcc.exe is not part of your system's Path variable. Add that directory location to the Path variable, then restart LabVIEW. It's just like step 10 in this tutorial <http://zone.ni.com/devzone/cda/tut/p/id/5412>, except you need to add the location of m68k-uclinux-gcc.exe, not Cygwin.

hello,

    The problem  above is   ok now.Thank you very much!

    There are still a problem as follows:

    Firstly, the GCC compiler in the freescale coldfire uclinux target  is different with  the GCC in the cygwin,isn't?do we  need to change the complier if i  use the ARM7(S3C44B0)?   which complier should we choose?the GCC in the cygwin? can you give me some advices about how to change the target to use in the arm7(s3c44b0)?thank you very much!

Yes, the cross-compiler for the ColdFire uCLinux target is not the same as Cygwin's gcc for Windows. The target implementation for the ColdFire target contains plug-in VIs that call the correct cross-compiler. You can view the plug-in VIs, and modify them to call other tool chains. That's part of the process of adding support for a new target.

labview\Targets\NI\Embedded\unix\m5329evb\unix_m5329evb_LEP_TargetPlugin\LEP_unix_m5329evb_ScriptCompiler.vi

Instructions on setting up the ColdFire target are located in chapter 2 of the Embedded Porting Guide (page 2-18).

hello,professor Michael

       i know that i should use the arm-elf-gcc complier in the target.in the plug-in VIs  i changed it.but when i build it,it occurs many errors as  follows:

when i make the makefile in the linux,there are also some errors(i have changed the m68k-uclinux-gcc with arm-elf-gcc):

CCGArrSupport2.c

maybe the porblem is the  files in the CCodeGen?could you give me some advices,thank you!

Hi,

What tool chain are you using? Are you using any compiler flags that tell the compiler not to add in the standard includes? The issue appears to be that the standard includes are not being included by default.

Please copy/paste the command line command being used for compiling and linking -- Perhaps this will point us to the problem.

hello,

  I used the arm-elf-gcc complier ,which is used for arm7 +uclinux.The cflags used in the target plugins and the makefile are showed in the accessory.

 I am not sure about the cflags in the files.

 Thank you very much!

Sorry,I forgot to add the accessory just now!

thank you !

Hi,

I'm having some trouble un-archiving the file you attached. I tried "tar -zxvf problems.tar", and it returned "not in gzip format". I tried -xvf, and it returned "This does not look like a tar archive".

hello,soryry,i tried again!

hello,Mr Michael

       The error occured in the Makefile( D:\program files\labview 8.5\Targets\NI\Embedded\unix\m5329evb\build)  disappeared when i don't compile the mcfqspi.c which  loctated in the D:\program files\labview 8.5\Targets\NI\Embedded\unix\m5329evb\drivers.

      now ,i want to ask you a question about  the use of the driver such as the mcfqspi.c.

Thank you!
