Hi!
Quite new to OpenBSD on ARM64 and, while I have a Gateworks newport
GW6304 running Linux, I'm keen to get OpenBSD running on it and was
hoping for a little nudge.
Following INSTALL.arm64, I wrote the miniroot64.fs to a microSD card
then added the vendor (cavium) dtb to the first partition but obviously
it didn't boot (which isn't that surprising I guess). I then boot the
working "linux" firmware to u-boot and tried a variety of manual loads
(following the OcteonTX SDK) of the binaries from the vfat partition
but no joy.
Using the approach that built the Linux bootable image I then attempted
to adapt it for OpenBSD to create a 'bsd.its' for u-boot (just to see
if I could get the kernel loading) via:
mkits.sh -o bsd.its -k bsd.gz -C gzip -v 'openbsd64'
mkimage -f bsd.its bsd.itb

I then try to simply boot that kernel via:

ERROR: can't get kernel image!
[ I'm wondering why I'm getting 'Unknown OS' when it was written as
OpenBSD - perhaps the gateworks u-boot was built without support for
non-Linux OSes (https://github.com/Gateworks/manifest-newport) ]
Anyway, any thoughts on this approach or should I be trying something
else like a TFTP boot?
Thanks,
Jamie.
