Hi JH, wks is the extension used by wic to generate different kind of flashable (partitioned) images. I never used it, but looking around ( https://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#command-bootloader ) I see two relevant arguments:
- *--append * - *--configfile* Check them in the link above. Here is an example for --append: https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/wic/canned-wks/directdisk-multi-rootfs.wks#L22 Digging a bit deeper it seems that you cannot feed a custom config to uboot via wic (and again, correct me if I'm wrong), but only for extlinux (see: https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/wic/plugins/source/bootimg-partition.py#L110 ) I do not have time to replicate your environment, so I'm just giving you suggestions.
