<div dir="ltr">The grub in buster already has all of the fixes like Ubuntu 18.04. It properly loads device tree from systab passed from firmware. This is a pretty important issue for simply booting arm systems so I don't know if it is worth it to backport the capability into the current grub or just not use stretch for any arm systems. We hacked around this but I would imagine it would save a lot of time for others to backport the arm64/armhf bits I mentioned.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 26, 2019 at 2:32 PM Colin Watson <<a href="mailto:cjwatson@debian.org">cjwatson@debian.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">On Tue, Feb 12, 2019 at 01:59:23AM +0000, Da Xue wrote:<br>

Could you try version 2.02+dfsg1-9 or newer, from buster? It has a very<br>
substantial reworking of the Linux loader on arm, so it'd be good to<br>
determine whether it suffers from the same problem.<br>
<br>
Thanks,<br>
