I'm in the process of upgrading from the dizzy branch to the fido branch, and
I'm still a little confused about some tune changes that I'm seeing. I'm using
an Atmel AT91SAM9G25 processor. The meta-atmel layer that I am using had
incorrectly set DEFAULTTUNE = "arm926ejs" which had been setting the
architecture to "arm926ejste". They fixed that here:
https://github.com/linux4sam/meta-atmel/commit/47238062c04ca97c2ea0570576072ad5b46ce261
and according to the commit message it should now be building with DEFAULTTUNE
(and the resulting architecture) set to "armv5te". However, when I build using
my autobuilder I am getting an architecture of "armv5e". From my
understanding, this means the compiler thinks the processor does not have Thumb
support. I've tried "arm926ejs" and "armv5te" for DEFAULTTUNE settings and it
hasn't made any difference.
I've checked the working directories for a few packages, and previously the
relevant gcc options were being set to: "-march=armv5te -marm -mthumb-interwork
-mtune=arm926ej-s". Now they are being set to: "-march=armv5e -marm
-mthumb-interwork". How do I get it back to building with march=armv5te?
Here is the autobuilder configuration that I am using:
[nightly-atmel-demo-fido]
builders: 'builder1'
repos: [{'poky':
{'repourl':'git://git.yoctoproject.org/poky',
'layerversion':{'core':'meta', 'yoctobsp':'meta-yocto-bsp',
'yocto':'meta-yocto', 'poky':'meta-poky'},
'branch':'fido'}},
{'meta-atmel':
{'repourl':'git://github.com/linux4sam/meta-atmel.git',
'branch':'fido'}},
{'meta-openembedded':
{'autoinclude':False,
'repourl':'git://git.openembedded.org/meta-openembedded',
'branch':'fido'}},
{'meta-qt5':
{'repourl':'git://github.com/meta-qt5/meta-qt5.git',
'branch':'fido'}}]
steps: [{'SetDest':{}},
{'CheckOutLayers': {}},
{'RunPreamble': {}},
{'GetDistroVersion' : {'distro': 'poky'}},
{'CreateAutoConf': {'machine': 'at91sam9x5ek', 'SDKMACHINE': 'i686',
'distro': 'poky-atmel', 'buildhistory': True, 'packages': 'ipk', 'atextappend':
'EXTRA_IMAGE_FEATURES = ""\nDEFAULTTUNE = "armv5te"\n'}},
{'CreateBBLayersConf': {'buildprovider' : 'yocto', 'layerdirs':
['meta-atmel', 'meta-qt5', 'meta-openembedded/meta-oe',
'meta-openembedded/meta-networking', 'meta-openembedded/meta-python']}},
{'BuildImages': {'images': 'atmel-demo-image'}},
{'SyncPersistDB' : {'commit' : True, 'distro':'poky'}},
{'PublishLayerTarballs':{}},
{'PublishArtifacts': {'artifacts': ['at91sam9x5ek', 'ipk']}}]
scheduler: [{'nightly-scheduler-atmel-fido' :
{'type':'Nightly',
'hour':'1',
'minute':'15',}}]
The resulting build configuration:
Build Configuration:
BB_VERSION = "1.26.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "Ubuntu-12.04"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "at91sam9x5ek"
DISTRO = "poky-atmel"
DISTRO_VERSION = "1.8.2"
TUNE_FEATURES = "arm armv5 thumb dsp"
TARGET_FPU = "soft"
meta
meta-yocto
meta-yocto-bsp = "fido:c9f0a99050ec0050f0dbcd55d0cd2ab18848113f"
meta-atmel = "fido:dd595e6e8ec7010cf646a9ca356b2e01f10e274c"
meta-qt5 = "fido:90919b9d86988e7da01fa2c0a07246b5b5600a5d"
meta-oe
meta-networking
meta-python = "fido:902964a4da26e46018d2a8d17dcdda1ac4627a39"
TUNE_FEATURES includes "thumb", but the compiler options aren't set for
armv5te. I've tried changing the DEFAULTTUNE specification in CreateAutoConf
to "arm926ejs" and I've had the same results. How do I get the architecture
set back correctly for the processor I'm using?
Thanks,
Bryan Evenson
