	* current aarch64 kernel image alone is 24MB: 24M tmp-glibc/deploy/images/raspberrypi4-64/Image-raspberrypi4-64-1-6.1.77+git0+43d1723dbe_77fc1fbcb5-r0.1-20110405230000.bin and with rpi-bootfiles it takes around 46MB (e.g. this is from kirkstone raspberrypi4-64 build): 2.0K boot.scr 2.0K cmdline.txt 4.0K fixup4cd.dat 4.0K fixup_cd.dat 4.0K uEnv.txt 6.0K fixup4.dat 8.0K fixup.dat 10K fixup4db.dat 10K fixup4x.dat 10K fixup_db.dat 10K fixup_x.dat 16K uboot.env 36K config.txt 52K bcm2711-rpi-4-b.dtb 52K bcm2711-rpi-400.dtb 52K bcm2711-rpi-cm4.dtb 52K bootcode.bin 126K overlays 558K kernel8.img 786K start4cd.elf 786K start_cd.elf 2.2M start4.elf 2.9M start.elf 2.9M start4x.elf 3.6M start4db.elf 3.6M start_x.elf 4.6M start_db.elf 23M Image * it is increased automatically to fit the content: tmp-glibc/deploy/images/raspberrypi4-64 $ sfdisk -l core-image-minimal-raspberrypi4-64.rootfs--1.0-r0-20110405230000.wic Disk core-image-minimal-raspberrypi4-64.rootfs--1.0-r0-20110405230000.wic: 241.2 MiB, 252915712 bytes, 493976 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x076c4a2a Device Boot Start End Sectors Size Id Type core-image-minimal-raspberrypi4-64.rootfs--1.0-r0-20110405230000.wic1 * 8192 157815 149624 73.1M c W95 FAT32 (LBA) core-image-minimal-raspberrypi4-64.rootfs--1.0-r0-20110405230000.wic2 163840 493975 330136 161.2M 83 Linux but if you want to update the kernel in place or add some additional files later, it might not be big enough, increase the minimal size from 20M to 100M * reminder (as I forgot about it before): "--size" is just minimum https://docs.yoctoproject.org/ref-manual/kickstart.html says: --size: The minimum partition size. Specify as an integer value optionally followed by one of the units “k” / “K” for kibibyte, “M” for mebibyte and “G” for gibibyte. The default unit if none is given is “M”. You do not need this option if you use --source. --fixed-size: The exact partition size. Specify as an integer value optionally followed by one of the units “k” / “K” for kibibyte, “M” for mebibyte and “G” for gibibyte. The default unit if none is given is “M”. Cannot be specify together with --size. An error occurs when assembling the disk image if the partition data is larger than --fixed-size. Signed-off-by: Martin Jansa <martin.jansa@gmail.com>
2018-03-07	sdimage-raspberrypi.wks: find /boot partition on mmcblk0	Peter A. Bigot
	Recently wic was modified to no longer exclude /boot from partitions added to fstab. The --on parameter in many kickstart specifications insufficiently resolved the MMC device, resulting in attempts to mount /dev/mmcblkp1 as boot when the device should be /dev/mmcblk0p1. With systemd the mount failure is an error and the system drops into emergency mode. Signed-off-by: Peter A. Bigot <pab@pabigot.com>
2017-03-11	wic: move sdimage-raspberrypi to toplevel wic location	Maciej Borzecki
	Wic supports picking up image files from toplevel LAYERDIR/wic directory. Using this location has the benefit that image files are easier to find (compare that to previously used scripts/lib/image/canned-wks/ location). Signed-off-by: Maciej Borzecki <maciej.borzecki@rndity.com>
