Untested but maybe the following works:

Hi

I can pass this build step

This is caused by the recent commit
https://git.buildroot.org/buildroot/commit/configs?id=4b2440b7dcc68369548c0f2be6984fe645fc6bb0
from Matthias Fritzsche. Matthias, are you sure you tested the
beaglebone_qt5_defconfig ?

Indeed, beaglebone_defconfig and beaglebone_qt5_defconfig don't use the
same kernel version, and the one used in beaglebone_qt5_defconfig
doesn't have the Beagle Bone Green Device Tree.

So either we should revert Matthias patch on beaglebone_qt5_defconfig,
or someone tests upgrading beaglebone_qt5_defconfig to the same kernel
version as the one used in beaglebone_defconfig.

This is due to the fact that we removed auto-calculation of the ext4
filesystem size in
https://git.buildroot.org/buildroot/commit/?id=c6bca8cef0310bc649240b451989457ce94a8358,
and we default to 60 MB for the filesystem size, which is not enough
for this demo. Fixing this is simple: send a patch that adds:

BR2_TARGET_ROOTFS_EXT2_BLOCKS="126976"

to beaglebone_qt5_defconfig (of course after testing that this size is
sufficient).

Thanks!

I did *not* test the beaglebone_qt5_defconfig as I expected it to be the
same as beaglebone_defconfig.

I prefer to update the linux version. But I can not fully runtime test
beaglebone_qt5_defconfig cause the BeagleBone Green does not have
display output onboard and I have no proper cape nor BeagleBone Black.

I already created a patch and my (pretty slow) build computer is
building an image. Tomorrow I can runtime test it.

kind regards

Preferred the upstreamable solution to disable examples/quick/demos/photoviewer
in case the qt5 widgets module is not available and submitted as a proper
