Installing Targetlink 2.6, GCC 2.95.2 and Axiom MPC555

We've had this web page up on the Rapita Systems website for some time now. As it seems to be of interest to quite a few visitors, we've decided to move it into the blog.

Installing GCC 2.95.2 for Targetlink (Windows)

This procedure details a step by step installation of GCC 2.95.2 for Targetlink 2.6 on Windows. 1. Download: cygwin; PowerPC GNU Toolkit v2.05; newlib-1.13.0.zip 2. Install cygwin c:\cygwin 3. Install PpcElfInstall.exe in c:\cygwin 4. Unzip newlib-1.13.0.zip in c:\cygwin\home\user 5. Open a cygwin console (Icon "Macraigor Cygwin Shell" on the desktop) 6. Start a cygwin console and fix the broken spec file: dos2unix.exe /usr/local/lib/gcc-lib/powerpc-elf/2.95.2/specs 7. Start a cygwin console and compile and install newlib:

cd
mkdir newlib_compile
cd newlib_compile
../newlib-1.13.0/configure --target=powerpc-elf
make
make install

Installing Targetlink 2.6 with GCC for MPC555 (Windows)

This procedure details a step-by-step installation of dSpace Targetlink 2.6 for a Axiom MPC555 Board and GCC on Windows. 1. Execute TL2.0.6_Setup.exe (found on Targetlink 2.6 Install CD) and follow the instructions 2. Install gcc for targetlink. (See the "how to" above) 3. Execute the file TL206_TSM_CME555_GNU2952.exe (should be provided in directory GNU/gcc_package/TSMCME555GNU/ TL206_TSM-CME555-GNU2952) 4. Edit the file C:\dSPACE\matlab\TL\Config\tl_global_options.m After "% insert list of generic target code generation modules here ..." , add :

i = i+1;
codeopt(i).name = 'Generic MPC5XX/GNU2952';
codeopt(i).targetDLL = 'AnsiTarget.dll';
codeopt(i).target = 'Generic';
codeopt(i).cc = ;
codeopt(i).targetDir = 'SrcFiles\MPC5xx\GNU2952';

After "% insert list of target simulation configurations here ...", add :

i = i+1;
simconfig(i).name = 'CME555/GNU2952';
simconfig(i).board = 'CME555';
simconfig(i).cc = 'GNU2952';
simconfig(i).myC = 'MPC5XX';
simconfig(i).config = 'TLSerPort.xml';
simconfig(i).makefile = 'MakeFile.mk';
simconfig(i).compilerRootEnv = 'MPC5XX_GNU2952_ROOT';

5. Set the environment variable MPC5XX_GNU2952_ROOT=c:\cygwin\usr\local 6. Add c:\cygwin\bin to the PATH variable 7. Edit the file C:\dSPACE\matlab\TL\SimFiles\CME555\GNU2952\makefile.mk as follows:

# ------------------------------------------------------
# Define environment variables
# ------------------------------------------------------
%setenv TMPDIR = $(D_WORK)
%setenv COMPILER_PATH = $(COMP_ROOT)\bin\
%setenv LIBRARY_PATH = $(COMP_ROOT)\lib\gcc-lib\powerpc-elf\2.95.2\include
%setenv C_INCLUDE_PATH = $(COMP_ROOT)\lib\gcc-lib\powerpc-elf\2.95.2\include
%setenv path = $(COMP_ROOT)\bin
[...]
# ------------------------------------------------------
# Specify tools
# ------------------------------------------------------
CC = $(COMP_ROOT)\bin\powerpc-elf-gcc.exe # compiler
AS = $(COMP_ROOT)\bin\powerpc-elf-as.exe # assembler
LD = $(COMP_ROOT)\bin\powerpc-elf-ld.exe # linker
CV = $(COMP_ROOT)\bin\powerpc-elf-objcopy.exe # object converter
PA = $(TL_ROOT)\exe\TLawk.exe # AWK

8. Finally, fix the .h files so that they can be used by cpp (unixstyle end of line). In a cygwin console:

cd /cygdrive/c/dSpace
find . -name *.h -exec dos2unix {} \;

Troubleshooting with Targetlink 2.6, GCC 2.95.2 and Axiom MPC555 Q: "Cmd timeout" error received after downloading the SW to the board A: Change the serial driver of the board to 'polling mode'. To do so, edit file comm_drv.c in c:\dSpace\matlab\TL\SimFiles\CME555\GNU2952:

#define POLLING
//#undef POLLING

Q: "Could not find file.c" error while building the target

A: This usually happens because the cygwin DLL can not be found. Even if c:\cygwin\bin is in the path, it may not find it. Workaround: Manually copy it on the current directory. Maybe launching a cygwin window, and therefore forcing loading the DLL can solve the problem.
