re: [HELP] How to create cross-compiler for e500

[Mark Nicholson]

Everard,

    I have been able to get linux running on an MPC8540.  I used gcc 3.3.2 
along with binutils 2.14.   Motorola claims to have put e500 patches into 
the open source community, but they haven't given me a branch name yet as 
to where the checked it in.

    Binutils 2.14 does have an assembler which will generate the e500 
instruction set. (I used linux-2.4.24 and glibc-2.3.2 for reference.)

    I built my cross compilers using 'crosstool' (available at 
http://kegel.com/crosstool/) and I setup a .dat file for the processor 
like this:

TARGET=powerpc-8540-linux-gnu
TARGET_CFLAGS="-O -msoft-float -mno-string -Wa,-me500"
GCC_EXTRA_CONFIG=""
GLIBC_EXTRA_CONFIG="--without-fp"


    The most important thing is to make sure that you use '-soft-float' 
along with generating libc without-fp.

    I'm not sure that this is an *official* compiler, but it works....

[HELP] How to create cross-compiler for e500

[Everard.Brown]

Hello,

I have a couple of queries:

a) Can advise me which version of binutils and gcc is recommended for
use with PPC e500 processors?

b) When building a cross-compiler for e500 embedded target, what is the
appropriate target name (e.g. e500-eabi or powerpc-eabi)?

Thanks in advance,
  Everard Brown
