Thank you very much for your help on the second issue! I was unaware of the=
 fact that another mkimage call is necessary. After taking a look at the th=
e references you provided, I was able to boot the system from an initramfs.

However, my current approach requires two manual steps after running Yocto=
: I need to call mkimage on the cpio.xz file and to extend/configure the U-=
Boot environment in the running system. Is there a way to automate this?

More specifically, is it possible to...
* have Yocto generate an initramfs.cpio.xz.uboot file instead of just an i=
nitramfs.cpio.xz file and to
* modify the default environment that Yocto will compile into the U-Boot b=
inary?
