MPC5634M starting point

[Andrei Chichak]

Thanks Thomas and Joel,

I have moved my tools and RTEMS code version up to 4.10.2. I'd like to take a peek at the 5674F BSP to see what kind of changes were necessary to make it go together. Would I just take the CVS head of the libbsp/powerpc arm?

Is there anything weird that I would have to do to configure the ppc version of GCC to generate appropriate code? I will be using a e200z3 processor, whereas the 5674F uses an e200z7.

I'm probably doing something wrong, but right out of the box there is a problem with the mpc5566evb BSP, wherein when I compile a simple printf hello world test program, the compile bombs with:

c:/opt/rtems-4.10/bin/../lib/gcc/powerpc-rtems4.10/4.4.6/../../../../powerpc-rtems4.10/bin/ld.exe:linkcmds.mpc5566evb:3: warning: redeclaration of memory region `ROM'

c:/opt/rtems-4.10/bin/../lib/gcc/powerpc-rtems4.10/4.4.6/../../../../powerpc-rtems4.10/bin/ld.exe:linkcmds.mpc5566evb:6: warning: redeclaration of memory region `NIRVANA'
c:/opt/rtems-4.10/bin/../lib/gcc/powerpc-rtems4.10/4.4.6/../../../../powerpc-rtems4.10/bin/ld.exe:linkcmds.mpc5566evb:23: error: redefinition of memory region alias `REGION_TEXT'

It looks like the linker files need a bit of work.
