[Buildroot] Kernel not configuring [PowerPC 603e]

[Buildroot] Kernel not configuring [PowerPC 603e]

[Andrea Provasi]

Hi all,
   I am trying to build a rootfs and a kernel with buildroot for a Lite5200
evaluation board from Freescale. The board has an MPC5200B powerpc (it's a
603e core)

I made buildroot menuconfig changing the config to "Advanced Configuration",
vmlinux binary image in uImage, and rootfs type ext2 gzip compressed. All
the rest is as per defconfig (I think)

All build goes fine through toolchain and uClib.

 When it is time to configure the kernel I get the following error:

==========================================================
You should create a .config for your kernel
and install it as /-linux-2.6.21.config

cp -dpf /-linux-2.6.21.config/opt/buildroot/project_build_powerpc/uclibc/linux-
2.6.21/.config
cp: impossibile fare stat di `/-linux-2.6.21.config': No such file or
directory
make: *** [/opt/buildroot/project_build_powerpc/uclibc/linux-2.6.21/.configured]
Error 1
===========================================================

this is quite expceted being the .config origin name wrong? (I may ask :-))

Looking into
the Makefile.in.advanced in the kernel package subtree,
/opt/buildroot/target/linux
seem that the calling make process is failing to export the variables:

BR2_BOARD_PATH and BR2_BOARD_NAME

I actuallyam NOT very keen in browsing the makefiles...I can't tell if it's
ME that I'm missing something or is anywhere anything I should set in the
menuconfig to define the two envvars?

Many thanks in advance for any help

Regads
Andy

[Buildroot] Kernel not configuring [PowerPC 603e]

[Andrea Provasi]

Thanks,
 one further question while I try that, since the lite5200_defconfig file is
in arch/ppc/config
subfolder of the linux sources, could I directly put that into the buildroot
menuconfig or
do I hae to copy/move it to the buildroot directory?

This si cause I intendo to build several FSs using the same buildroot, as I
have another 2
powerPC board with different specs: an MPC8360 (which is still a 603e) and a
PowerPC405GX.

For all of them I'd like to build a Kernel and root filesystem and I wonder
how to differentiate te
.config for the different kernels.

Cheers
Andy

[Buildroot] Kernel not configuring [PowerPC 603e]

Hi Andrea,

you can use make saveconfig and make BOARD=xxx getconfig to save and get 
the configuration set (kernel/uclibc/busybox) into the local/$(BOARD) 
subdirectory. I think you also have to specify the correct board name 
into the right menuconfig entry.

Your board support needs to define these BOARD support variables,
(involves editing makefiles)
or you have to change the default path to the linux config file to something
which exists.
