bootimg: Do not force FAT32 on all images, it violates the FAT specification

2012-04-14T22:11:51+00:00

Fixes [YOCTO #1940] do_bootimg was performing the FAT overhead calculations assuming FAT32 and then forcing the use of FAT32 with "-F 32" to mkdosfs. The FAT specification is clear on cluster count being the determining factor for FAT size (even if the fs string is set to FAT32, go figure). Syslinux follows this spec, and rightly so, resulting in a failure on core-image-minimal: syslinux: zero FAT sectors (FAT12/16) Drop the "-F 32" from mkdosfs to allow it to select the appropriate FAT size based on cluster count. Leave the FAT overhead calculation in FAT32. This will result in a little extra padding for really small images, but not enough extra to justify recalculating for FAT12 and FAT16. Tested with a core-image-minimal build for atom-pc. do_bootimg completed successfully, and the resulting image was FAT16.

bootimg: Fix a math thinko in the block count calculation

2012-04-14T22:11:43+00:00

Fixes [YOCTO #1852] ... again. The conversion from sectors to blocks was multiplying by 2 instead of dividing by 2. Blocks are 1024 bytes, sectors are 512 bytes. The result was images being much larger than intended.

bootimg: Account for FAT filesystem overhead in image size

2012-04-14T22:11:38+00:00

Fixes [YOCTO #1852] The bootimg class wasn't accounting for non-trivial amount of space required by the directory entries and FATs for the FAT filesystem. This patch attempts to make an accurate prediction of FAT overhead and adjusts the image size accordingly. It assumes no more than 16 directory entries per directory (which fit in a single sector). It also assumes 8.3 filenames. With the ceiling functions rounding up to full sectors and tracks, these assumptions seem reasonable. In order to ensure the calculations are accurate, this patch forces the FAT size to 32, rather than allowing mkdosfs to automatically select 12, 16, or 32 depending on the image being built. Tested by setting BOOTIMG_EXTRA_SPACE=0 and building core-image-minimal and core-image-sato for fri2-noemgd from meta-intel.

bootimg: Use mcopy to construct the hddimg

2012-04-14T22:10:49+00:00

Fixes [YOCTO 2138] The initial directory support (-d) added to mkdosfs has proven to be incomplete and non-compliant with FAT. Rather than continue to maintain this feature and work around the various issues, we can use mcopy to construct the image. bootimg.bbclass already depends on mtools-native (although it may not have needed to previously). No new dependencies are introduced. The image created passes dosfsck cleanly. Remove the call to dosfsck. mcopy reported an error with the image we were creating: Total number of sectors (107574) not a multiple of sectors per track (32)! Add some logic to ensure the total sector count is an integral number of sectors per track, including forcing the logical sector size to 512 in the mkdosfs command. The du -bks arguments are contradictory, -b is equivalent to "--apparent-size --block-size=1" and -k is --block-size=1K. If reordered, -kbs will report the disk usage in bytes insteadk of 1k blocks. Eliminate the ambiguity by using: du --apparent-size -ks (From OE-Core rev: 92d2ea1a306354c6565a1b05b51b5719e481840f) Signed-off-by: Darren Hart CC: Nitin A.

bitbake: machine specific sysroots implementation

2011-01-25T12:25:46+00:00

This commit changes the sysroots path to be machine specific. Changes includes: 1) STAGING_DIR_TARGET and STRAGING_DIR_HOST points to machine specific paths. 2) task stamp files. Adding ${MACHINE} info into stamp files for do_populate_sysroots and do_package tasks. Add a BB_STAMPTASK_BLACKLIST to keep native, nativesdk, crosssdk, and cross-canadian stamp unchanged. 3) siteconfig path. Separate the site config path for different machines to avoid one machine adopting the cache file of another machine. 4) sstate. Add machine name to sstate manifest file. Change relocation code for sstate paths since sysroot is machine. Keep native, nativesdk, crosssdk, and cross-canadian unchanged. 5) toolchain scripts. Change the environment path to point to machine specific sysroots in toolchain scripts bbclass. 6) Relocate la files when populating to a different machine of the same architecture. 7) Exclude STAGING_DIR_TARGET and STAGING_DIR_HOST parameter from sstate siginfo since they contain ${MACHINE} information.

bitbake.conf/base.bbclass: Rename the staging directory to sysroots and the populate_staging task to populate_sysroot

2009-11-13T12:15:42+00:00

This change makes the purpose of the staging directory more obvious and the taskname more true to what it now actually does. The layout version number is increased due to the change in layout but code to convert existing directories and insert a symlink for backwards compatibility is included.
