[oe] [OE-core] core-image-tiny-initramfs failing to parse because of WIC (WKS_FULL_PATH, )

[Ed Bartosh]

Hi Martin,

Sorry for the delay. I missedd your message somehow.

I can't reproduce this. Tried with latest poky and latest oe-core +
bitbake. I built core-image-tiny-initramfs from scratch and bitbake -e
busybox works for me just fine.

Can you provide more details about your setup, please?
