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 the references you provided, I was able to boot the system from an initramfs.<br /><br />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?<br /><br />More specifically, is it possible to...<br />
<ol>
<li>have Yocto generate an initramfs.cpio.xz.uboot file instead of just an initramfs.cpio.xz file and to</li>
<li>modify the default environment that Yocto will compile into the U-Boot binary?</li>
</ol>
