Hi,
I'm trying to update the tune files for MicroBlaze, specifically the
microblazeel (little endian) with soft-float.
I get the following error while trying to build:
ERROR: Unable to determine endianness for architecture ''
ERROR: Unable to determine endianness for architecture ''
ERROR: Please add your architecture to siteinfo.bbclass
ERROR: Please add your architecture to siteinfo.bbclass
ERROR: Unable to parse
/tool/yocto/meta-openembedded/toolchain-layer/recipes-devtools/gcc/libgcc_4.6.bb:
Exited with "1"--:--
ERROR: Unable to determine endianness for architecture ''
ERROR: Please add your architecture to siteinfo.bbclass
ERROR: Command execution failed: Exited with 1
The site info.bbclass already has the appropriate endian definitions for
microblaze and microblazeel defined:
def siteinfo_data(d):
archinfo = {
"allarch": "endian-little bit-32", # bogus, but better than
special-casing the checks below for allarch
"aarch64": "endian-little bit-64 arm-common",
"arm": "endian-little bit-32 arm-common",
"armeb": "endian-big bit-32 arm-common",
"avr32": "endian-big bit-32 avr32-common",
"bfin": "endian-little bit-32 bfin-common",
"i386": "endian-little bit-32 ix86-common",
"i486": "endian-little bit-32 ix86-common",
"i586": "endian-little bit-32 ix86-common",
"i686": "endian-little bit-32 ix86-common",
"ia64": "endian-little bit-64",
"microblaze": "endian-big bit-32 microblaze-common",
"microblazeel": "endian-little bit-32 microblaze-common",
This is the contents of my arch-microblaze.inc file:
# Microblaze ABI interface definition
# Four defined ABIs, all combinations of:
# *) Hard/Soft Floating Point
# *) Big Endian (PLB System) / Little Endian (AXI System)
DEFAULTTUNE ?= "microblaze"
TUNE_PKGARCH = "${TUNE_PKGARCH_tune-${DEFAULTTUNE}}"
ABIEXTENSION ?= ""
TUNEVALID[fpu-hard] = "Use hardware FPU."
TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "fpu-hard",
"-mhard-float", "", d)}"
TUNE_ARCH .= "${@bb.utils.contains("TUNE_FEATURES", "fpu-hard", "microblaze",

BASE_LIB_tune-microblaze = "lib"
TUNE_PKGARCH_tune-microblaze = "microblaze"
PACKAGE_EXTRA_ARCHS_tune-microblaze = "microblaze"
# Tune options for MicroBlaze little endian soft-float
DEFAULTTUNE ?= "microblazeel-nf"
This is the contents of my tune-microblazeel-nf.inc file:
require conf/machine/include/microblaze/arch-microblaze.inc
TUNEVALID[microblazeel-nf] = "Enable MicroBlaze little endian soft-float
optimizations"
TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "microblazeel-nf",
"-mcpu=v8.40b", "", d)}"
TUNE_PKGARCH = "${@bb.utils.contains("TUNE_FEATURES", "microblazeel-nf",
"microblazeel-nf", "microblazeel-nf", d)}"
AVAILTUNES += "microblazeel-nf"
TUNE_FEATURES_tune-microblazeel-nf ?= "mlittle-endian fpu-soft"
BASE_LIB_tune-microblazeel-nf = "lib"
TUNE_PKGARCH_tune-microblazeel-nf = "microblazeel-nf"
PACKAGE_EXTRA_ARCHS_tune-microblazeel-nf = "microblazeel-nf"
What am I missing that is causing this error ?
