[meta-freescale] Problems building fsl-image-gui for TARGET_FPU=vfp-neon [SOLVED]

Tue Nov 5 07:21:33 PST 2013

Yes don't mix swfp and hwfp builds.   That was my comment on freescale community.

Hi,

I'm trying to build fsl-image-gui for soft float as I am using Mono in a project and Mono currently doesn't appear to support hard float.

Git checkouts I'm using are all recent (i.e. within days),

meta-yocto        = "ajlennon/sqlite:3ab777991480aa4bff79130bd889ed25eba72fdc"
meta-fsl-arm      = "master:88117e976c16f22b9bbfeb26a52088e31f1d0c4d"
meta-fsl-arm-extra = "master:5b753d3d130ed6932715329d0e887a015e628766"
meta-fsl-demos    = "master:87233da97fe0ead245773e092acb56faa24f3835"
meta-mono         = "master:ceae2e324a03bf2c616c98a69b4e16f7b7a6af03"

I wasn't entirely clear on how to change the tuning to use the neon registers instead
of hard float, and in the end I added the following line to local.conf

DEFAULTTUNE_mx6 ?= "cortexa9-neon"

This gets me building with bitbake reporting,

TUNE_FEATURES     = "armv7a vfp neon cortexa9"
TARGET_FPU        = "vfp-neon"

I had some trouble rebuilding and in the end I removed the tmp/ directory and restarted
the build. This gets me further but I'm now erroring on gpu-viv-bin-mx6q do_package()

Can anybody advise whether I'm overriding the default hfp tuning correctly, and what might be
going wrong here?

It looks to me as though there was some kind of issue with the dependencies as the .spec file being built still had references to hardfp packages

I found this comment at the FSL community forum:

"I tried this on imx6qsabresd and have no issues.   Right before release we did have problems with
disabling hwfp correctly but it was enabled in the final update. Also I've seen multiple times that switching
between hwfp and swfp can corrupt build states.  I always keep these completely separate builds both
with cache and tmp directories."

When I created a new build tree and built for softfp within that tree it all seems to work.

Many thanks,

Alex Lennon

I can "bitbake jack" without any errors, but when I add "jack" to my

Is "jack" missing from the imx6qsabresd feed or do I need to add some

kind of depends?

Neither; this is common for people starting to Yocto to make this mistake.

Basically you need to check the binary packages it builds.

When you do:

$: bitbake jack

You are saying ... hey bitbake, please process jack recipe. This has no

direct relation to the binaries you get as result.

When you add something in IMAGE_INSTALL or similar, you are asking for the

image to install the /binary/. For jack case, the binaries are:

http://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-multimedi

a/jack/jack_0.121.0.bb?h=dora#n38

Most probably, you're looking for jack-server binary.
