This is for fixing the problem:
1) bitbake core-image-sato-sdk with MACHINE=qemux86
2) bitbake core-image-sato with with MACHINE=crownbay
The qemux86's PACKAGE_ARCH is i586, the crownbay's is core2, but several
i586 packages will be installed into crownbay's rootfs though there are
core2 packages. For example, there are:
xserver-xorg*_1.11.2-r7_i586.ipk
xserver-xorg*_1.9.3-r1_core2.ipk
The crownbay.conf says:
PREFERRED_VERSION_xserver-xorg ?= "1.9.3"
What the crownbay's image needs is xserver-xorg*_1.9.3-r1_core2.ipk, but
the xserver-xorg*_1.11.2-r7_i586.ipk will be installed, this is
incorrect.
This is caused by opkg's selecting mechanism: when more than one
candidate is found, it will use the higher version one and ignore the
arch priority.
we have several conf files which set the PREFERRED_VERSION_pkg = "..." ,
but there is no such a mechanism which can let us tell the opkg to
install the preferred version. When the preferred version is higher,
this is OK, but if the preferred version is lower, there would be
problems:
1) Most of the packages are core2 in the image, but several of them are
i586, though we have built the core2 ones, this seems strange.
2) What's worse is that the image may not work since the preferred
version pkg is not installed.
We have set the arch priority clearly in the opkg.conf, I think that
respect to the arch priority is reasonable during the image generation.
Add the "--select-higher-version" option to let the user have another
choice, the default is no.
