Commit 2b524321a25c35c5f987b8331e41b49d3b2e2d2b removed bbclass for
building SD card images in favor of using wic. This commit adds a mic
source plugin that prepares a useable boot partition as part of wic's
image creation process. The plugin defines a new source type -
beaglebonebootimg, similarly to the existing bootimg-{efi,pcbios} in
current poky tree.An example *.wks for setting up the partitions is provided as well. Usage: wic create beaglebonesdimage -e core-image-minimal Signed-off-by: Maciej Borzecki <[email protected]> Signed-off-by: Maciek Borzecki <[email protected]> --- scripts/lib/image/canned-wks/beaglebonesdimage.wks | 5 + .../lib/mic/plugins/source/beaglebonebootimg.py | 109 +++++++++++++++++++++ 2 files changed, 114 insertions(+) create mode 100644 scripts/lib/image/canned-wks/beaglebonesdimage.wks create mode 100644 scripts/lib/mic/plugins/source/beaglebonebootimg.py diff --git a/scripts/lib/image/canned-wks/beaglebonesdimage.wks b/scripts/lib/image/canned-wks/beaglebonesdimage.wks new file mode 100644 index 0000000..efd302d --- /dev/null +++ b/scripts/lib/image/canned-wks/beaglebonesdimage.wks @@ -0,0 +1,5 @@ +# short-description: Create SD card image for BeagleBone +# long-description: Creates a partitioned SD card image for use with BeagleBone + +part /boot --source beaglebonebootimg --ondisk mmcblk0 --fstype=vfat --label boot --active --align 1024 --size 10 +part / --source rootfs --ondisk mmcblk0 --fstype=ext3 --label root --align 1024 diff --git a/scripts/lib/mic/plugins/source/beaglebonebootimg.py b/scripts/lib/mic/plugins/source/beaglebonebootimg.py new file mode 100644 index 0000000..969632b --- /dev/null +++ b/scripts/lib/mic/plugins/source/beaglebonebootimg.py @@ -0,0 +1,109 @@ +# ex:ts=4:sw=4:sts=4:et +# -*- tab-width: 4; c-basic-offset: 4; indent-tabs-mode: nil -*- +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License version 2 as +# published by the Free Software Foundation. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
