Hi
I have just bought an old Xilinx ML507 and I am trying to build yocto,
but I find some problems building the minimal image
I am a yocto newbie ... thus I wonder if I am missing something important.
My setup: Linux Fedora 18 64 bits
I hope I am following the correct procedure:
git clone git://git.yoctoproject.org/poky
cd poky
git clone git://git.yoctoproject.org/meta-xilinx -b
master-xilinx-ml507-gcc-4.7 meta-xilinx
git clone git://git.openembedded.org/meta-openembedded
. oe-init-build-env
My bblayers contains
BBLAYERS ?= " \
/home/andrea/src/FPGA/poky/meta \
/home/andrea/src/FPGA/poky/meta-yocto \
/home/andrea/src/FPGA/poky/meta-yocto-bsp \
/home/andrea/src/FPGA/poky/meta-openembedded/toolchain-layer \

/home/andrea/src/FPGA/poky/meta-xilinx \
/home/andrea/src/FPGA/poky/meta-angstrom \
"
My local.conf contains
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "-j 4"
XILINX_LOC ?= "/opt/Xilinx/13.3/ISE_DS"
MACHINE ?= "virtex-5-ml507-powerpc-440"

ABORT,${DL_DIR},100M,1K \
ABORT,${SSTATE_DIR},100M,1K"
CONF_VERSION = "1"
The problems I have found (and someway fixed) are:
1) when I do "bitbake meta-toolchain" I get an error complaining that
the compiler is not able to build for powerpc with FPU
Fix: I have changed the ml507 rules to include just the soft FPU

#@DESCRIPTION: Machine configuration for the Xilinx ML507 FPGA

KERNEL_DEVICETREE = "${S}/arch/powerpc/boot/dts/virtex440-ml507.dts"
2) the libffi library version "3.0.12" has a small bug (a misplaced
#ifndef), which is fixed in version "3.0.13"
Fix: I have added to my local.conf
PREFERRED_VERSION_libffi = "3.0.13"
PREFERRED_VERSION_libffi-native = "3.0.13"
This way the toolchain compiles properly
When I try "bitbake core-image-minimal" I get 2 problems:
1) the Xilinx git repository has moved from git.xilinx.com to
github.com/Xilinx
Fix: I have changed the links in u-boot and linux-xilinx

2) bitbake complains about the license missing from the u-boot recipe
3) I have troubles also with the git.denx.de repository, which I can
easily clone by hand but not by bitbake
Fix: I have added the required variables at the end (and fixed the git
links)

There still some problems which stop my build ...
I will get them to you in a following email
All the best
