Using --size in the imx-imx-boot-bootpart.wks.in to set size of /boot partition does not result in a 256MiB partition as expected but in a ~332MiB one. Indeed, --size ensures --extra-space (default 10MiB) is added to actual data size and furthermore applies --overhead-factor (default 1.3) to the wanted size. This is exactly the case here as 256 * 1.3 = 332.8. Use --fixed-size instead to force the /boot partition to be exactly 256MiB just as it is indicated in the comments of this file. Consequently, the `do_image_wic` task will also fail if data copied in this partition are too large at creation. Signed-off-by: Jonathan GUILLOT <jonathan@joggee.fr>
