there is ROOTFS_POSTPROCESS_COMMAND for tweaking images after the fact. Take a look at core-image.bbclass you still would need 30 image recipes though, another thing you could try is bundle all splash images into one package and _somehow_ use the right one when booting the image on a given device. _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
