wic: Add 512 Byte alignment to --offset

2020-08-22T14:46:55+00:00

Allows the --offset argument to use the "s" or "S" suffix to specify that it is reporting the number of 512 byte sectors. This is required for some SoCs where the mask ROM looks for an item at a sector that isn't aligned to a 1KB boundary.

wic: Fix --extra-space argument handling

2020-06-12T07:25:04+00:00

467f84e12b ("wic: Add --offset argument for partitions") broke the --extra-space argument handling in wic. Fix the option and add a unit test for the argument. (From OE-Core rev: 87722a92c18f94917c8f70afc8cd0763462a5c25) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

wic: Add --offset argument for partitions

2020-06-04T12:27:32+00:00

Add support for an --offset argument when defining a partition. Many SoCs require that boot partitions be located at specific offsets. Prior to this argument, most WKS files were using the --align attribute to specify the location of these fixed partitions but this is not ideal because in the event that the partition couldn't be placed in the specified location, wic would move it to the next sector with that alignment, often preventing the device from booting. Unlike the --align argument, wic will fail if a partition cannot be placed at the exact offset specified with --offset. Changes in V2: * Fixed a small typo that prevented test_fixed_size_error from passing (From OE-Core rev: 467f84e12b96bc977d57575023517dd6f8ef7f29) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

wic: root: Add an opt. destination on include-path

2020-04-26T13:00:50+00:00

Allow specifying an optional destination to include-path and make the option aware of permissions and owners. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --fstype=ext4 --include-path core-image-minimal-mtdutils export/ --include-path hello on the .wks file.

wic: Add --change-directory argument

2020-04-26T13:00:50+00:00

This option allows to specify which part of a rootfs is going to be included, the same way the -C argument on tar. Thanks to this option we can make sure the permissions and usernames on the target partition are respected, and also simplify the creation of splitted partitons, not neeting to invoke external vars or using .wks.in files. Eg: part / --source rootfs --ondisk sda --fstype=ext4 --exclude-path=etc/ part /etc --source rootfs --fstype=ext4 --change-directory=etc Cc: Paul Barker (From OE-Core rev: 2265d089a58e1f78f26d623ee667c420cb1c3bd4) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Richard Purdie

wic: Add --embed-rootfs argument

2020-04-06T15:45:11+00:00

This option adds the content of a rootfs on a specific location on the rootfs. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --embed-rootfs target-image /export --embed-rootfs target-image2 /export2 on the .wks file.

wic: Honor APPEND

2020-02-15T22:42:14+00:00

APPEND is used to add additional parameters to kernel by features, such as read-only-rootfs. So we should honor this variable when we compose the kernel parameter in wic. I know we also can resolve this kind of issue by using the .wks.in template introduced by commit 42e870c5ed4b ("image_types.bbclass: support template .wks.in files for wic"), but the APPEND is needed by all the wks, it would seems pretty ridiculous to me to change all the .wks to .wks.in and then foist the APPEND into them. So the APPEND is definitely deserved to export to the wic directly. [Yocto #12809] (From OE-Core rev: 18981b8a457104391dfd94938c247eac04e4ed50) Signed-off-by: Kevin Hao Signed-off-by: Richard Purdie

wic: Add --include-path argument

2020-01-10T21:18:22+00:00

This option adds the contents of the given path to a partition built with the rootfs source plugin. The path is relative to the directory in which wic is running not the rootfs itself so use of an absolute path is recommended. This option is most useful when multiple copies of the rootfs are added to an image and it is required to add extra content to only one of these copies. This option only has an effect with the rootfs source plugin. (From OE-Core rev: d4cd27a9837426e809190548a83c6c7c76505114) Signed-off-by: Paul Barker Signed-off-by: Richard Purdie

wic: Add partition type for msdos partition tables

2019-08-12T15:23:57+00:00

In order to create a msdos partition table disk image that can auto expand after the image is copied to an SD card, wic needs the ability to have a primary partition as the last entry. The desired use case is to be able to create an A/B update partition image scheme with a /var volume that can be auto expanded to the remainder of the SD card at run time. The typical .wks file will look similar to the following: bootloader --ptable msdos part / --source rawcopy --sourceparams="file=u-boot.imx" \ --ondisk mmcblk --no-table --align 1 --size 1 part /boot --source bootimg-partition \ --ondisk mmcblk --fstype=vfat --label boot --active --align 4 --size 16 part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot_b --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot_b --align 4 --type logical part /var --source rawcopy --sourceparams="file=imx6_var.otaimg" \ --ondisk mmcblk --fstype=ext4 --label fluxdata --align 4 Without the patch applied, wic will generate an SD card image that looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48008s 132467s 84460s primary ext4 3 132472s 454467s 321996s primary ext4 4 454471s 890939s 436469s extended lba 5 454472s 538931s 84460s logical ext4 6 538936s 860931s 321996s logical ext4 7 860936s 890939s 30004s logical ext4 boot With the patch applied a primary partition can be created at the end of the image which can be expanded to fill the free space on the media where the image has been copied, which looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48007s 860931s 812925s extended lba 5 48008s 132467s 84460s logical ext4 6 132472s 454467s 321996s logical ext4 7 454472s 538931s 84460s logical ext4 8 538936s 860931s 321996s logical ext4 3 860936s 890939s 30004s primary ext4 boot (From OE-Core rev: 56add7cc547e0113cdf980579d1421b14cc233e5) Signed-off-by: Jason Wessel Signed-off-by: Richard Purdie
