Support for Odroid XU4?

T

tenox

Hi,

How can one persuade / help FreeBSD get official support for some specific ARM board?

I would like to see a full support for Odroid XU4. This is because their HC2 product (XU4 based) is a perfect NAS hardware. I would love to run FreeBSD/ZFS on it.

Is there some form of a bounty or other process to get it kick started?

Thanks!
 
There are lots of people who wants stuff. Some even want to pay for stuff. However the one thing FreeBSD needs most is more developers - that is the only thing that can help accelerate development.
Still, very few of the people who wants something from FreeBSD wants to learn how to be a FreeBSD developer (in fairness, some do).

Curious that.
 
It's a quite old post, but I don't want to reopen a new one.

I am wondering, whether the FreeBSD-kernel would be able to boot on Odroid XU4 or is it not working at all?
Actually I configured/compiled a FreeBSD-kernel using the EXYNOS5420 configuration, but always stuck when the kernel actually should start (see attachment).

I had to modify the u-boot loader (README.odroid), and shift the first (msdos) partition by a few blocks, but the rest was a standard FreeBSD (13.0) image (apart from the kernel, of course).

Any ideas what I am missing?

Thanks a lot.

Could you be more specific, which 2019 source codes you mean? 11.3, 11.4, 12.1 or older? Or which revision?
 
git switch stable/12

Unfortunately, still no success.

Compiled a kernel using stable/12, but it still stops at the same position.

I was also trying to set the dtb-file (version of stable/12) manually by
load -t dtb exynos5422-odroidxu4.dtb
Alternatively I tried also exynos5422-odroidxu3.dtb, but no change.

Does it make sense to use an earlier version? Or could the version of bootarm.efi also interfere?
 
We do not see a single line of the system kernel output - this means that we have something wrong with the console driver or the definition of the console port in the DTS file.
It seems to me.
 
This was also one of my thoughts.

So I used the dtb-file from a working NetBSD-Image, but unfortunately without change. Actually a closer look reveilled that NetBSD and FreeBSD use the same dts-files.

So I does not seem to be the dtb/dts-file.

I find the porters-handbook not that easy.
