I'm trying to build a fit image for an ARM target and am struggling to
configure kernel-fitimage in such a way that it includes zImage as the fitImage
kernel instead of linux.bin. zImage is significantly smaller than linux.bin
and can be used on my system without needing to modify u-boot's
CONFIG_SYS_BOOTM_LEN due to the large kernel size.
I've tried several permutations of the following settings in my machine.conf
file without success:
KERNEL_CLASSES += "kernel-fitimage"
KERNEL_IMAGETYPE = "fitImage"
KERNEL_IMAGETYPES += "zImage"
KERNEL_IMAGETYPE_REPLACEMENT = "zImage"
I've also tried patterning my config on
oe-core/meta/lib/oeqa/selftest/cases/fitimage.py which uses several
combinations of the settings above. In every case, linux.bin is the kernel
included in the resulting fitImage. Is there some combination of settings that
will enable zImage in my fit image?
I believe the issue is this line here:
https://git.openembedded.org/openembedded-core/tree/meta/classes-recipe/kernel-fitimage.bbclass#n572
I would naively suggest to replace linux.bin with
${KERNEL_IMAGETYPE_REPLACEMENT} and see where this leads you?
Cheers,
Quentin
