Hello forum
I read this post, but I still don't get how to set up the rootfs into the SD card, or the built-in eMMC.
At some point I've read to dd vmlinux.kpart, but I didn't get exactly where it could be done.
My trial failed to dd to the ESP, nothing's going. I tried to copy as per wiki directions, but it fails.
I also tried to add a new entry in the extlinux.conf, but it seems that it takes just one kernel and one partition. Something like a fake syslinux, I taught.
EDIT
I dismiss this post, further discussion are going on here
