Hi Gordan,
Thanks for the reply. Firstly, I must apologise for mis-spelling your
name and this botched reply, which I've 'copied & pasted' from the list
archive. My mails from the list have been being bounced (without me
realising) since I set my server to reject mails from domains without an
MX entry and as my server is 'Unable to determine MX associated with
<lists.redsleeve.org>' the messages were rejected . I made that change
due to being overrun with spam. I've changed it back now.
Ah, that would be because lists.redsleeve.org isn't a domain but a
hostname. :-/
There have been numerous issues with various mailing lists recently due
to some MSAs implementing RFC non-compliant policies. For example, IIRC
GMX and Yahoo are no longer accepting mailing list emails because the
from address doesn't match the server. Which one could argue is fair
enough, but unfortunately, it is the way mailing lists have worked since
forever...
Anyway, back on topic ...

I've been trying to get hold of one of these for a while now, but no
Gigabyte distributor in UK has been willing to supply one, and given the
price tag of about €800 I wasn't prepared to take my chances on ordering
one from abroad in case of any future warranty claims which would
involve expensive international shipping.
Have you been able to source one of these in UK?
I got one from
Xcase,https://www.xcase.co.uk/server-motherboards/gigabyte-mp30-ar0-with-appliedmicror-x-gene1r-processor.html.
As you say, the price is a bit OTT but they have stock.
Oooo! That is so very tempting... Maybe after payday. And maybe it's
time for a 64-bit ARMv8 build of RedSleeve...
Kind of annoying, though, as I only got kernel ZFS (as opposed to
zfs-fuse which I've been using and maintaining on ARM for years now)
working on 32-bit ARM very recently...
Having said all that, this is an ARMv8 64-bit board. I am not even sure
off the top of my head if ARMv8 64-bit architecture is ABI compatible
with 32-bit ARM code. If you are looking to try one of these (or a
similar board) out, I would suggest you look at getting it up and
running with CentOS 7 ARMv8 port.
That was one of my plans (I have got Debian Jessie on it currently, but using
the kernel provided with the board).
I will go ahead and try anyway but the docs state it needs to have a UEFI
bootloader and the Rev 1.1 board I've got only has uboot.
In fairness, there is nothing actually wrong with using uboot. UEFI is a
can of worms I have been tolerating out of lack of choice, but
personally, given a choice between entirely closed source UEFI blob boot
loader and uboot, I'd choose the latter every time.
I'm loathe to try and upgrade to UEFI using the info a
thttps://fedoraproject.org/wiki/Architectures/AArch64/Hardware/Mustang?rd=Architectures/ARM/AArch64/Mustang#Upgrade_to_UEFI
as it isn't truly a Mustang board.

I'd hate to screw it up and end up with a £600 paperweight.
I have pinged Gigabyte about UEFI firmware but not had a response.
But do you _actually_ need UEFI for any particular reason? What is the
advantage? If anyting, uboot supports loading the kernel from a
half-decent file system (such as ext4) , whereas UEFI requires a FAT
partition to work.
When I asked a similar question about
this board there a few months ago, they seemed to think it should work
with their standard ARMv8 image.
I'll try with uboot but I guess the kernel install will not succeed, though I
may get a rootfs.
I wouldn't be so sure about the kernel install not succeeding. Most
things are in place to support wrapping the kernel for uboot (look at
/sbin/new-kernel-pkg, particularly the mkimage lines). Uboot is actually
remarkably prolific and well supported.
Please let us know how you get on, and more importantly, if you manage
to get hold of one of those boards from a supplier in UK (ideally one
that is likely to be around for at least the duration of the warranty
period).
I'll let you know if I have any joy, or otherwise.
Please do. I've been very much wanting an ARM server with a decent
amount of RAM for years. Going from never having an ARM machine with
more than 3.5GB of RAM (and that's pretty recent, the vast majority of
my ARM collection only has 512MB) to 128GB would be pretty amazing. And
if it turns out to be possible to run a soft-float armv5tel chroot on an
ARMv8 system, it would completely revolutionize the distro build times.
