[Buildroot] Buildroot for target PowerPC 405 (on Xilinx XUPV2p Board)

[Mirko ROCCO]

Hi,
i'm trying to compile buildroot... this is my scenario:

HOST=i386-pc-linux
TARGET=powerpc 405 (i don't know if with FPU or not...)

I have the XUPV2P Board of Xilinx, and I would want to install on it an
linuz kernel (linux-2.6.xlnx.git kernel from xilinx!)

Which combination of uclibc, GCC, busybox, binutils, etc. etc. is better to
choose in "menuconfig"in my case?

Now I'm working with
Busybox: 1.12.x
uCLibc: 0.9.29
GCC: (really i try every combination with same result :-( ...)
binutils: 2.18

I never had success in compilation!!!

Can someone help me please?

Thanks, regards,

Mirko ROCCO

405 would be without fpu as opposed to 405fp

Works fine for me with my tree ?) for gcc-4.3.2, gcc-trunk, current binutils and
latest kernel and current uClibc (or trunk), current busybox (or trunk). All of
the stuff you mention below is old by that measure (and didn't work for me).

[Buildroot] Buildroot for target PowerPC 405 (on Xilinx XUPV2p Board)

[Mirko ROCCO]

Hi Bernhard!
I try to use your tree as you suggest me!

Unfortunately I recive this error and i don't know how to solve it:

/usr/bin/install: manca l'operando per il file di destinazione dopo
`/home/mirko/Documenti/TESI/BUILDROOT/buildroot-Bernhard/powerpc_nofpu_toolchain/linux/.config'
Usare `/usr/bin/install --help' per ulteriori informazioni.
make: ***
[/home/mirko/Documenti/TESI/BUILDROOT/buildroot-Bernhard/powerpc_nofpu_toolchain/linux/.configured]
Error 1

Any idea?

The folder "linux" doesn't exist in
"../buildroot-Bernhard/powerpc_nofpu_toolchain/", but instead exist
"linux-2.6.26.5". This is the folder that buildroot create every time i
launch "make", so is useless to rename the folder!

Hope you can help me, thanks!

Mirko ROCCO

You did not enable a kernel.
make menuconfig
goto the "kernel" and select "Kernel type" linux.
Enable "linux kernel" and set ".config file" to the
kernel config you want to use (e.g. "br2.ppc-405-kernel.config").
If you do not yet have a kernel .config file prepared, then you
can copy one of the ppc defconfig to that very file to the toplevel
directory.

Please keep this on the mailing list, it may be helpful for others too.

If the kernel is reasonable new then you can use that kernel and appropriate
.config, yes.

If you select Toolchain -> Kernel Headers -> Linux 2.6 snapshot then
a linux-2.6.tar.bz2 tarball is used which has to contain the kernel
sources in the "linux-2.6/" directory.

So, either you git clone git://kernel.org/.... linux-2.6
for an upstream kernel or you can
mv linux-kernel-2.6-from-vendor linux-2.6
# cd linux-2.6 && make mrproper
tar -cjf dl/linux-2.6.tar.bz2 linux-2.6
where "dl/" is the BR2_DL_DIR from your buildroot .config.
