Poky issues with tune-cortexa8 and a custom machine

Poky issues with tune-cortexa8 and a custom machine

Hi all,

I've created a custom machine to match my hardware.
This hw is arm based with cortexa8 architecture, so my machine file
(myarm.conf) uses:

require conf/machine/include/tune-cortexa8.inc

For the image I use:

bitbake poky-image-minimal

This compiles everything fine but when it starts composing the rootfs by
installing ipk's I get errors about some missing packages.
I've found that the error is due to the fact that poky is compiling two work
trees:

build/tmp/work/myarm-poky-linux-gnueabi

and

build/tmp/work/armv7a-poky-linux-gnueabi

And the missing ipk's are in the armv7a tree!

I've also noticed that the armv7a "target" definition is inside
tune-cortexa8.inc...
So...what am I doing wrong?

Thank you.

best regards

Salvo

Does this also happen if you use rpms instead of ipks? (Set in
local.conf). Can you post the error you receive?

This is normal, there are machine packages and architecture packages,
and shouldn't cause a problem with installation.

I think there was a patch from Joshua post-1.0 to fix a bug that sounds like 
this one (rev e235357841311a4681c747cebcc5e51940aec606).

We should probably consider this for a point release.

Cheers,

Hi all,

I finally fixed this issue by adding:

PACKAGE_ARCHS += "armv7a"

to tune-cortexa8.inc

In fact the armv7a arch was missing from the PACKAGE_ARCHS variable so it
was not "seen" when composing the final image.
Do you think it could be a valid patch?
For me...it works!
