In previous releases of GDP, .sdimg images for Minnowboard have been released. This process was handled manually via scripting:
'dd if=/dev/zero of="genivi-dev-platform-minnowboard.sdimg" bs=1024 count=1M
sudo losetup -d /dev/loop0
sudo losetup /dev/loop0 "genivi-dev-platform-minnowboard.sdimg"
sudo bash ./mkefidisk.sh /dev/loop0 genivi-dev-platform-intel-corei7-64.hddimg /dev/mmcblk0
sudo losetup -d /dev/loop0'
This is not suitable for CI (go.cd) as workers for valid reasons do not have sudo privileges or the ability to mount.
Currently I'm looking at the use of Wic:
I've been able to use the wic template for mkefdisk, to create a dd'able USB image. This needs some modification (like SD (mmcblk) by default) etc. This template would eventually be commited to meta-genivi-dev, in a scripts directory.
