Re: Working toolchain for ppc405???

[Richard Guinto <argie_guinto at yahoo dot com>]

Hi Olexiy,

I tried this toolchain today with 2.4.14 kernel, but I
still got kernel panic (see output below).  I will try
it with 2.6.15.6 kernel later today...  Do you do some
patching in your kernel to make it work with your
virtex board?  (I only change the xparameters.h file
as mentioned in ppc mailing list).

I noticed that when I built the toolchain, it fails in
hello.c test, "PATH_MAX" undeclared, so I'm not sure
if  I got the correct crosstool configuration same as
yours.  I just created the file 
gcc-3.4.6-glibc-2.3.6.dat and pass it in eval command
in demo-ppc405.sh.

The contents of the dat file I created is:

BINUTILS_DIR=binutils-2.16.1
GCC_DIR=gcc-3.4.6
GLIBC_DIR=glibc-2.3.6
LINUX_DIR=
LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.6
GLIBC_ADDON_OPTIONS==linuxthreads,
SHARED_MODE=--enable-shared


Have you checked it with your Virtex-II board?  We
will be actually using Virtex-II FG456 board as the
final board, but for now, I'm using Virtex4 FX12.


Thanks.



Richard
