Hi,
I was playing around with the meta-xilinx layer and tried to build
"core-image-minimal" for the spartan6 without success. I was wondering
if anyone has tried this lately and/or if anyone has any tips to
suggest?
configuration:
I'm using the latest HEAD:
BB_VERSION = "1.15.3"
TARGET_ARCH = "microblaze"
TARGET_OS = "linux"
MACHINE = "spartan6-lx9mb"
DISTRO = "poky"
DISTRO_VERSION = "1.2+snapshot-20120904"
TUNE_FEATURES = "m32 microblazeel"
TARGET_FPU = "soft"
meta
meta-yocto = "master:37c8597e7600385367257e8a513e003947ebef5b"
meta-xilinx = "master:d196fa93c7ff5e080d4c44e2b83aed472f32b2c7"
conf/local.conf:
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "-j 4"
MACHINE ??= "spartan6-lx9mb"
DL_DIR = "/home/trevor/devel/Downloads"
DISTRO ?= "poky"
PACKAGE_CLASSES ?= "package_rpm"
EXTRA_IMAGE_FEATURES = "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
CONF_VERSION = "1"
conf/bblayers.conf:
LCONF_VERSION = "5"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \
/home/trevor/devel/yocto/git-method/poky/meta \
/home/trevor/devel/yocto/git-method/poky/meta-yocto \
/home/trevor/devel/yocto/git-method/poky/meta-xilinx \
"
issues:
The first problem I encountered was trying to build gcc-cross-initial:
This target does not support --with-float.
I was able to get around this with the following (very silly) patch:
diff --git a/meta/recipes-devtools/gcc/gcc-common.inc
b/meta/recipes-devtools/gcc/gcc-common.inc
index 72180db..cb3a8cf 100644
--- a/meta/recipes-devtools/gcc/gcc-common.inc
+++ b/meta/recipes-devtools/gcc/gcc-common.inc
@@ -12,8 +12,6 @@ FILESDIR = "${@os.path.dirname(d.getVar('FILE',1))}/gcc-${PV}"
def get_gcc_fpu_setting(bb, d):
if d.getVar('ARMPKGSFX_EABI', True) == "hf" and
d.getVar('TRANSLATED_TARGET_ARCH', True) == "arm":
return "--with-float=hard"
- if d.getVar('TARGET_FPU', True) in [ 'soft' ]:
- return "--with-float=soft"
if d.getVar('TARGET_FPU', True) in [ 'ppc-efd' ]:
return "--enable-e500_double"
return ""

Although I could get past this point, bitbaking again led to the
following problem with the same, gcc-cross-initial, recipe:
